1
00:00:01,202 --> 00:00:05,177
Attention, viewers. Do not try anything
you are about to see at home.

2
00:00:05,178 --> 00:00:08,079
We are what you call experts.

3
00:00:09,648 --> 00:00:12,750
On this combustible
episode of "mythbusters"...

4
00:00:12,751 --> 00:00:15,088
I see good things
in our future.

5
00:00:15,089 --> 00:00:16,905
...We test a tale

6
00:00:16,906 --> 00:00:18,878
That brings out the teenage boy
in all of us.

7
00:00:18,879 --> 00:00:21,100
Dude, you got to be careful.

8
00:00:21,101 --> 00:00:25,074
It's nonstop fireworks
for Tory, Grant, and Kari...

9
00:00:25,075 --> 00:00:27,403
When in peril, I will use
one of my co-workers

10
00:00:27,404 --> 00:00:29,165
As a human shield.

11
00:00:29,166 --> 00:00:31,826
...As they tackle
the myth of the human skyrocket.

12
00:00:31,827 --> 00:00:33,240
One.

13
00:00:33,241 --> 00:00:34,983
Oh, my God.

14
00:00:34,984 --> 00:00:37,344
Meantime, Adam and Jamie
try turning the tables

15
00:00:37,345 --> 00:00:40,300
On their favorite episode
of "CSI"...

16
00:00:40,301 --> 00:00:42,109
I am aimed.

17
00:00:42,110 --> 00:00:45,603
...To see if combining two
supposedly nonlethal weapons...

18
00:00:45,604 --> 00:00:48,925
Welcome, earthlings.
We mean you no harm.

19
00:00:48,926 --> 00:00:52,450
...Could actually
make them a deadly duo.

20
00:00:52,451 --> 00:00:53,990
There's your fireball.

21
00:00:53,991 --> 00:00:57,142
With any luck, we will end up
with a charred corpse.

22
00:00:57,143 --> 00:00:59,287
Stand clear.
I'm going hot.

23
00:01:03,237 --> 00:01:04,878
Who are the Mythbusters?

24
00:01:06,387 --> 00:01:07,991
Adam Savage...
Aah!

25
00:01:07,992 --> 00:01:10,066
That is science.
...And Jamie Hyneman.

26
00:01:10,067 --> 00:01:12,945
Things are gonna start to get
a little crazy in here.

27
00:01:12,946 --> 00:01:17,596
Between them, more than 30 years
of special-effects experience.

28
00:01:17,597 --> 00:01:19,100
Joining them --

29
00:01:19,101 --> 00:01:22,110
Grant Imahara...
Burn!

30
00:01:22,111 --> 00:01:23,214
...Kari Byron...

31
00:01:23,215 --> 00:01:24,384
Let's do it.

32
00:01:24,385 --> 00:01:25,922
...And Tory Belleci.

33
00:01:25,923 --> 00:01:27,192
But don't worry.
We're not gonna give up.

34
00:01:27,193 --> 00:01:28,998
They don't just tell the myths.

35
00:01:28,999 --> 00:01:32,611
They put them to the test.

36
00:01:32,612 --> 00:01:35,688
-- <font color="#ffff00">Captions by vita -&www.M</font>

37
00:01:35,689 --> 00:01:38,865
Captions paid for by
discovery communications

38
00:01:38,866 --> 00:01:44,382
First up, a shocking tale
of crime-scene chaos.

39
00:01:44,383 --> 00:01:46,820
So, what do we got?

40
00:01:46,821 --> 00:01:48,322
Well, you remember
a few months ago

41
00:01:48,323 --> 00:01:49,827
That you and I did
a cameo on "CSI"?

42
00:01:49,828 --> 00:01:53,135
I do. We played scientists
in lab coats.

43
00:01:53,136 --> 00:01:55,943
It was about a perp who had
spontaneously combusted

44
00:01:55,944 --> 00:01:57,246
After being hit with a stun gun,

45
00:01:57,247 --> 00:01:59,384
And it turned out,
upon investigation,

46
00:01:59,385 --> 00:02:01,422
That prior to being hit
with the stun gun,

47
00:02:01,423 --> 00:02:02,860
He was pepper-sprayed,

48
00:02:02,861 --> 00:02:05,667
And that the pepper spray
had a flammable component in it

49
00:02:05,668 --> 00:02:08,239
Which, when coupled
with the spark of the stun gun,

50
00:02:08,240 --> 00:02:11,079
Caused him to burst
into a huge fireball.

51
00:02:11,080 --> 00:02:13,451
And guess what happened
after that episode aired.

52
00:02:13,452 --> 00:02:15,389
We got a ton of requests

53
00:02:15,390 --> 00:02:17,060
To do it ourselves
and test it for real.

54
00:02:17,061 --> 00:02:18,530
Exactly right.

55
00:02:18,531 --> 00:02:21,971
It would appear that not only
did we make a cameo on "CSI,"

56
00:02:21,972 --> 00:02:25,177
But "CSI" is making
a cameo on "Mythbusters."

57
00:02:26,715 --> 00:02:30,856
The science unfolds
in the C.S.I. Lab

58
00:02:30,857 --> 00:02:33,996
As Nick Stokes shows
that stun gun plus pepper spray

59
00:02:33,997 --> 00:02:37,303
Equals an instant,
massive fireball.

60
00:02:37,304 --> 00:02:39,106
It's a nice bit of tv,

61
00:02:39,107 --> 00:02:43,314
But we all want to know
if it works in real life.

62
00:02:43,315 --> 00:02:46,320
Well, if I'm gonna potentially
set something on fire,

63
00:02:46,321 --> 00:02:48,992
I think right here
under Jamie's exhaust hood

64
00:02:48,993 --> 00:02:51,429
Is as good a place as any
to do it safely.

65
00:02:51,430 --> 00:02:54,001
The boys have made
a bold decision

66
00:02:54,002 --> 00:02:56,437
To simply set up the scene
and go for it.

67
00:02:56,438 --> 00:03:00,112
Standing in for the victim
is one dead pig.

68
00:03:00,113 --> 00:03:02,050
We use pigs a lot on this show

69
00:03:02,051 --> 00:03:04,121
Because they're
great human analogues.

70
00:03:04,122 --> 00:03:07,360
But we're not wasting them
because they're too darn tasty.

71
00:03:07,361 --> 00:03:09,732
In fact, after we're done
with him here,

72
00:03:09,733 --> 00:03:12,069
I'm taking him home
and cooking him up.

73
00:03:12,070 --> 00:03:13,906
You ready? I am.
Let's hook it up.

74
00:03:13,907 --> 00:03:15,508
Okay.

75
00:03:16,976 --> 00:03:20,213
With the pig analogue
securely fastened,

76
00:03:20,214 --> 00:03:23,520
Adam fits a small flannel shirt
they've been saving

77
00:03:23,521 --> 00:03:26,626
For just the right occasion.

78
00:03:26,627 --> 00:03:28,463
There we go.

79
00:03:28,464 --> 00:03:30,133
Now Jamie unloads

80
00:03:30,134 --> 00:03:32,805
A whole can
of police-issue pepper spray.

81
00:03:32,806 --> 00:03:37,746
All right, time to take him down
with the stun gun.

82
00:03:37,747 --> 00:03:41,718
And hopefully replicate
that "CSI" fireball.

83
00:03:41,719 --> 00:03:44,256
I am aimed, and...

84
00:03:44,257 --> 00:03:45,925
3...

85
00:03:45,926 --> 00:03:47,427
I got to say, I don't think

86
00:03:47,428 --> 00:03:49,364
We're gonna get fire
on this one.

87
00:03:49,365 --> 00:03:50,366
Okay.

88
00:03:50,367 --> 00:03:52,569
...2...1...

89
00:03:59,047 --> 00:04:00,348
What do you know?
I was right.

90
00:04:00,349 --> 00:04:02,719
Yep. No fire.

91
00:04:02,720 --> 00:04:04,121
That's disappointing.

92
00:04:04,122 --> 00:04:07,059
That's putting it
mildly. It's a complete dud.

93
00:04:07,060 --> 00:04:11,032
Even Adam's surprised by
the totality of the failure.

94
00:04:11,033 --> 00:04:12,134
I don't know what to say.

95
00:04:12,135 --> 00:04:13,770
We did everything right --
no flaming pig.

96
00:04:13,771 --> 00:04:14,871
Yeah, well, there are

97
00:04:14,872 --> 00:04:16,373
A number of different things
going on here,

98
00:04:16,374 --> 00:04:18,175
And I think we need to break
them out separately

99
00:04:18,176 --> 00:04:19,275
To see what's happening.

100
00:04:19,276 --> 00:04:20,810
Before we call it.
Yeah.

101
00:04:20,811 --> 00:04:23,279
Okay, let's do that.

102
00:04:23,280 --> 00:04:24,914
And here's the breakdown.

103
00:04:24,915 --> 00:04:27,349
Successful combustion
needs three things.

104
00:04:27,350 --> 00:04:30,284
The first is oxygen,
and there's plenty of that.

105
00:04:30,285 --> 00:04:32,453
Second is something combustible and
there's plent of that --

106
00:04:32,454 --> 00:04:34,721
Supposedly the pepper-soaked shirt.

107
00:04:34,722 --> 00:04:37,690
Third is a reliable source
of ignition.

108
00:04:37,691 --> 00:04:42,327
So let's reboot this myth by
reexamining the stun gun.

109
00:04:42,328 --> 00:04:44,930
The operation of these stun guns
is relatively simple,

110
00:04:44,931 --> 00:04:46,298
And it happens in two phases.

111
00:04:46,299 --> 00:04:47,499
Allow me to illustrate.

112
00:04:47,500 --> 00:04:49,934
The first phase --
when you pull the trigger,

113
00:04:49,935 --> 00:04:52,736
The gun fires a pair of shiny
little barbs across the room

114
00:04:52,737 --> 00:04:55,372
That embed themselves
right into your skin.

115
00:04:55,373 --> 00:04:57,240
And the second part --
it starts pumping voltage

116
00:04:57,241 --> 00:04:59,409
Through these wires into those
barbs and into your body,

117
00:04:59,410 --> 00:05:00,977
And when that voltage
gets to your body,

118
00:05:00,978 --> 00:05:02,712
It starts interrupting
your brain's ability

119
00:05:02,713 --> 00:05:04,047
To tell your muscles
what to do,

120
00:05:04,048 --> 00:05:06,082
And you pretty much collapse
in a heap on the ground.

121
00:05:06,083 --> 00:05:08,851
But the question remains --

122
00:05:08,852 --> 00:05:11,620
Can even 50,000 volts
produce enough spark

123
00:05:11,621 --> 00:05:13,689
To start a human bonfire?

124
00:05:15,693 --> 00:05:18,495
There you go.
Plenty of sparks.

125
00:05:18,496 --> 00:05:20,730
I have to say,
I'm kind of surprised.

126
00:05:20,731 --> 00:05:22,398
I was actually expecting
that once those barbs

127
00:05:22,399 --> 00:05:23,967
Embedded themselves
in the pig flesh,

128
00:05:23,968 --> 00:05:26,203
They'd complete a circuit and we
wouldn't see any sparks,

129
00:05:26,204 --> 00:05:27,404
But we do.

130
00:05:27,405 --> 00:05:29,138
Look at that.

131
00:05:29,139 --> 00:05:32,173
I was also surprised
that the barbs

132
00:05:32,174 --> 00:05:35,339
Were creating sparks while they
were fully embedded in the pig,

133
00:05:35,340 --> 00:05:37,469
But it's easy to understand why.

134
00:05:37,470 --> 00:05:39,698
The company has decided
it's most efficient

135
00:05:39,699 --> 00:05:41,965
To simply tie a knot
in the end of the wire

136
00:05:41,966 --> 00:05:44,966
So it locks into the hole
like so,

137
00:05:44,967 --> 00:05:47,136
And they know that,
given the fact

138
00:05:47,137 --> 00:05:49,638
That they're using such
high voltage in these things,

139
00:05:49,639 --> 00:05:51,906
That the spark will jump
across into the needle

140
00:05:51,907 --> 00:05:53,775
And do its job.

141
00:05:53,776 --> 00:05:55,476
But that jumping spark

142
00:05:55,477 --> 00:05:58,412
Also serves as a potential
source of ignition.

143
00:05:58,413 --> 00:06:01,815
But will it be
big enough to ignite the myth?

144
00:06:01,816 --> 00:06:04,651
You know, we've dabbled
with small sparks before.

145
00:06:04,652 --> 00:06:09,688
How hard can it be to blow up
a room full of gasoline?

146
00:06:09,689 --> 00:06:12,923
And often enough,
we're left disappointed.

147
00:06:12,924 --> 00:06:14,991
Nothing. What a shocker.

148
00:06:14,992 --> 00:06:18,293
So, ideally, they'd like
a much bigger spark.

149
00:06:18,294 --> 00:06:22,030
And they've worked out a way
that perfectly fits the myth.

150
00:06:22,031 --> 00:06:24,432
All right, let me describe
the experimental setup here.

151
00:06:24,433 --> 00:06:26,901
This ham hock is our perp.

152
00:06:26,902 --> 00:06:29,803
This barb is the barb
that's in his skin.

153
00:06:29,804 --> 00:06:33,473
This vinyl shower curtain
is our perp's clothing.

154
00:06:33,474 --> 00:06:34,874
And this barb is the barb

155
00:06:34,875 --> 00:06:36,942
That didn't make it all the way
to the perp's skin

156
00:06:36,943 --> 00:06:38,244
'cause it got caught up
in his clothing.

157
00:06:38,245 --> 00:06:40,412
Let's see what happens.

158
00:06:40,413 --> 00:06:42,981
It's an intriguing
twist on the basic test.

159
00:06:42,982 --> 00:06:45,317
But will it work?

160
00:06:46,786 --> 00:06:48,219
That's what I'm talking about.

161
00:06:48,220 --> 00:06:49,887
Nice big 3-centimeter spark

162
00:06:49,888 --> 00:06:52,790
Through the clothes
into the guy's flesh.

163
00:06:52,791 --> 00:06:54,492
Bingo.

164
00:06:54,493 --> 00:06:56,794
That's a big tick
for reliable ignition.

165
00:06:56,795 --> 00:06:59,729
Next up, they'll be pushing
the button on pepper spray.

166
00:07:02,232 --> 00:07:03,732
Our second myth has

167
00:07:03,733 --> 00:07:06,467
Blatant disregard
for self-preservation

168
00:07:06,468 --> 00:07:07,935
Written all over it.

169
00:07:07,936 --> 00:07:09,837
So, a guy is
lighting off fireworks

170
00:07:09,838 --> 00:07:11,539
At a German fireworks festival,

171
00:07:11,540 --> 00:07:13,841
And he decides to take
an action figure,

172
00:07:13,842 --> 00:07:16,513
Strap a skyrocket to it,
and send it flying.

173
00:07:16,514 --> 00:07:18,649
Well, I used to do that
all the time when I was kid.

174
00:07:18,650 --> 00:07:19,983
Yeah, but that's not the myth.

175
00:07:19,984 --> 00:07:23,219
The myth is that he
then decides to step it up

176
00:07:23,220 --> 00:07:25,121
And strap the fireworks
to himself.

177
00:07:25,122 --> 00:07:27,723
So he gets around
400 skyrockets,

178
00:07:27,724 --> 00:07:30,325
He attaches them to himself,
he builds a ramp,

179
00:07:30,326 --> 00:07:31,994
He lights them all off,
and whoosh.

180
00:07:31,995 --> 00:07:36,231
He goes flying
150 feet over a lake

181
00:07:36,232 --> 00:07:37,667
And splashes down to safety.

182
00:07:37,668 --> 00:07:40,268
The details are
delightfully vague.

183
00:07:40,269 --> 00:07:43,904
All we know is that some guy
builds some kind of ramp

184
00:07:43,905 --> 00:07:46,840
And launched himself
with 400 skyrockets.

185
00:07:46,841 --> 00:07:48,876
Is that even remotely possible,

186
00:07:48,877 --> 00:07:52,813
Or is it a special kind
of stupid?

187
00:07:52,814 --> 00:07:55,815
All we do know for sure is that
he wasn't a professional.

188
00:07:55,816 --> 00:07:57,748
So likely the fireworks he used
were over-the-counter.

189
00:07:57,749 --> 00:08:00,349
All right, well, why don't we
just start there?

190
00:08:00,350 --> 00:08:01,950
We'll take
some of these skyrockets,

191
00:08:01,951 --> 00:08:03,251
We'll add some weight,
and find out

192
00:08:03,252 --> 00:08:05,418
Exactly how much one of these
skyrockets can lift.

193
00:08:05,419 --> 00:08:07,650
Good idea,
because if we can find

194
00:08:07,651 --> 00:08:09,518
The carrying capacity
of a single firework,

195
00:08:09,519 --> 00:08:11,786
Then we can calculate
how many it's gonna take

196
00:08:11,787 --> 00:08:14,288
To lift an average man --
somebody like 200 pounds.

197
00:08:14,289 --> 00:08:16,757
So they book the bomb range

198
00:08:16,758 --> 00:08:19,626
And get hold of the biggest
over-the-counter skyrockets

199
00:08:19,627 --> 00:08:21,061
Money can buy.

200
00:08:21,062 --> 00:08:23,697
We're out
at the alameda county bomb range

201
00:08:23,698 --> 00:08:25,965
So we can test the most powerful
consumer fireworks

202
00:08:25,966 --> 00:08:27,300
That we can find.

203
00:08:27,301 --> 00:08:29,635
Then, with the help
of a high-speed camera

204
00:08:29,636 --> 00:08:32,438
And one of the biggest scales
we've ever used...

205
00:08:32,439 --> 00:08:33,639
Does this look straight?

206
00:08:33,640 --> 00:08:36,275
We'll time how long
it takes to get

207
00:08:36,276 --> 00:08:39,210
From the bottom of the scale
all the way to the top.

208
00:08:39,211 --> 00:08:41,612
That, plus knowing
how long the scale is,

209
00:08:41,613 --> 00:08:43,047
Will give us the speed.

210
00:08:43,048 --> 00:08:45,782
Once we have the speed,
we'll find the carrying capacity

211
00:08:45,783 --> 00:08:47,983
By adding weight
to the tip of the firework

212
00:08:47,984 --> 00:08:49,851
Until it slows it down by 50%.

213
00:08:49,852 --> 00:08:52,653
And we'll call that
our carrying capacity.

214
00:08:52,654 --> 00:08:54,922
The plan is rock solid,

215
00:08:54,923 --> 00:08:57,991
But it still needs
some caressing and finessing.

216
00:08:57,992 --> 00:09:00,592
Now, for these tests, it's
important that these skyrockets

217
00:09:00,593 --> 00:09:02,760
Have identical flight paths.

218
00:09:02,761 --> 00:09:04,095
So I've hooked up
this steel cable

219
00:09:04,096 --> 00:09:06,029
That we can connect
our fireworks to

220
00:09:06,030 --> 00:09:08,598
So that way, each test,
we have the same path

221
00:09:08,599 --> 00:09:11,199
But we do not change the thrust
of the rocket.

222
00:09:11,200 --> 00:09:12,833
The first control rocket

223
00:09:12,834 --> 00:09:14,935
Carries
no extra weight whatsoever.

224
00:09:14,936 --> 00:09:16,836
Here we go.

225
00:09:18,038 --> 00:09:21,606
Run! Run! Run!

226
00:09:26,076 --> 00:09:27,910
Whoa.

227
00:09:27,911 --> 00:09:29,178
Blink and you miss it.

228
00:09:29,179 --> 00:09:31,748
But the high-speed camera

229
00:09:31,749 --> 00:09:34,722
Captures and records
every detail.

230
00:09:34,723 --> 00:09:38,166
Okay, so we went 32 feet
in .4 secos.

231
00:09:38,167 --> 00:09:40,503
Okay, that's 80 feet
per second.

232
00:09:40,504 --> 00:09:43,308
That's around 55 miles an hour.
That's a pretty good speed.

233
00:09:43,309 --> 00:09:45,143
Great. Let's add some weight.
All right.

234
00:09:45,144 --> 00:09:47,011
The extra weight comes

235
00:09:47,012 --> 00:09:49,046
Courtesy of some
heavy-duty nuts.

236
00:09:49,047 --> 00:09:50,381
Each one weighs exactly...

237
00:09:50,382 --> 00:09:51,716
50 grams.

238
00:09:51,717 --> 00:09:53,785
All right.
This is perfect.

239
00:09:53,786 --> 00:09:55,419
So I'll just glue it
to the top of the rocket,

240
00:09:55,420 --> 00:09:57,889
And we'll find out if this
affects the thrust of it.

241
00:09:57,890 --> 00:09:59,190
Yeah.

242
00:09:59,191 --> 00:10:00,958
Kari lights the fuse...
There we go.

243
00:10:00,959 --> 00:10:02,693
...Then scampers.

244
00:10:05,063 --> 00:10:06,964
Oh!

245
00:10:08,132 --> 00:10:11,366
The extra weight
only swed the rocket by 20%.

246
00:10:11,367 --> 00:10:14,771
So instead of adding just one
more nut to the next rocket,

247
00:10:14,772 --> 00:10:17,206
They'll add two.

248
00:10:17,207 --> 00:10:20,910
Okay, this is consumer-grade
firework with 150-gram load.

249
00:10:20,911 --> 00:10:22,378
Here we go.

250
00:10:27,183 --> 00:10:28,651
Yeah!

251
00:10:28,652 --> 00:10:31,253
Definitely slowed it down.
Definitely.

252
00:10:31,254 --> 00:10:33,956
Yeah, we might have found
the number. I like that.

253
00:10:33,957 --> 00:10:35,090
The replay confirms

254
00:10:35,091 --> 00:10:36,623
That they've got
what they wanted --

255
00:10:36,624 --> 00:10:38,858
A 50% reduction in speed.

256
00:10:38,859 --> 00:10:42,790
That's the good news.
Now here's the bad news.

257
00:10:42,791 --> 00:10:45,893
Well, with 400 rockets,
150 grams,

258
00:10:45,894 --> 00:10:47,328
That's 60 kilograms.

259
00:10:47,329 --> 00:10:49,796
That's a carrying capacity
of about 130 pounds.

260
00:10:50,014 --> 00:10:53,333
But wait. The guy alone without all his
gear in this myth is 200 pounds.

261
00:10:53,334 --> 00:10:54,992
Yeah, it's not looking good for the myth.

262
00:10:54,993 --> 00:10:58,361
I mean, you would need well over
400 rockets to lift this guy.

263
00:10:58,362 --> 00:11:01,196
In fact, they'd need around 800

264
00:11:01,197 --> 00:11:04,265
Of these U.S.-Made rockets
to haul a full-grown man,

265
00:11:04,266 --> 00:11:08,201
So here's hoping
somebody's got a plan "b."

266
00:11:08,836 --> 00:11:11,704
After the break,
Adam and Jamie suit up

267
00:11:11,705 --> 00:11:14,739
For a spectacular
pepper-spray shootout.

268
00:11:14,740 --> 00:11:17,274
It's not everybody who gets to
come to work in their jammies.

269
00:11:25,275 --> 00:11:28,744
Out at the treasure
island fire test facility,

270
00:11:28,745 --> 00:11:32,579
Adam and Jamie plan
to ignite some pepper spray.

271
00:11:34,414 --> 00:11:36,748
I love it out here.

272
00:11:36,749 --> 00:11:39,283
They've already shown
that the spark from a stun gun

273
00:11:39,284 --> 00:11:41,352
Could have some kick to it.

274
00:11:41,353 --> 00:11:44,422
Now to advance
the investigation.

275
00:11:44,423 --> 00:11:46,424
Is pepper spray flammable?

276
00:11:46,425 --> 00:11:48,959
And if it is,
which one is the most flammable?

277
00:11:48,960 --> 00:11:51,161
Here's our methodology
for finding out.

278
00:11:51,162 --> 00:11:52,662
We're gonna take
each of our samples

279
00:11:52,663 --> 00:11:55,731
And spray it from this location
over this open flame,

280
00:11:55,732 --> 00:11:59,667
Both from 6 inches away like
this and from 18 inches away.

281
00:11:59,668 --> 00:12:02,101
Different sprays
have different recipes,

282
00:12:02,102 --> 00:12:04,270
So we'll test
five different types,

283
00:12:04,271 --> 00:12:07,639
Some of which aren't used
by the California cops.

284
00:12:07,640 --> 00:12:09,274
These pepper sprays
are nonlethal,

285
00:12:09,275 --> 00:12:10,876
But they are
really pretty nasty.

286
00:12:10,877 --> 00:12:13,214
In fact, when we were testing
with them earlier,

287
00:12:13,215 --> 00:12:14,984
I managed to get
some on my hands,

288
00:12:14,985 --> 00:12:16,786
And my skin was irritated
for days.

289
00:12:16,787 --> 00:12:19,855
The crew that was taping this
was coughing and sneezing.

290
00:12:19,856 --> 00:12:21,823
It was really
kind of unpleasant.

291
00:12:21,824 --> 00:12:26,127
So this time around, we've got
ahold of some levechem suits

292
00:12:26,128 --> 00:12:27,628
That we're gonna be wearing

293
00:12:27,629 --> 00:12:30,964
So we can focus on the testing
and not about how bad we feel.

294
00:12:30,965 --> 00:12:33,733
Adam's already dressed
for success,

295
00:12:33,734 --> 00:12:36,302
So Jamie, uh, follows suit.

296
00:12:36,303 --> 00:12:40,872
It's not everybody who gets to
come to work in their jammies.

297
00:12:40,873 --> 00:12:42,941
So a persistent rumor

298
00:12:42,942 --> 00:12:45,309
Is confirmed
by the great man himself.

299
00:12:45,310 --> 00:12:48,679
Jamie does go to bed
wearing hazmat pajamas.

300
00:12:48,680 --> 00:12:52,548
Welcome, earthlings.
We mean you no harm.

301
00:12:52,549 --> 00:12:57,286
Our first five samples tested
from 6 inches away.

302
00:12:57,287 --> 00:12:59,888
The first one's
supposed to be nonflammable.

303
00:12:59,889 --> 00:13:01,589
Let's see if it's true.

304
00:13:01,590 --> 00:13:03,291
Just for the record,

305
00:13:03,292 --> 00:13:05,759
That 6-inch gap is exactly
the industry standard

306
00:13:05,760 --> 00:13:07,227
For testing flammability.

307
00:13:07,228 --> 00:13:09,462
All right.
You ready for number 1?

308
00:13:09,463 --> 00:13:10,529
Yep.

309
00:13:10,530 --> 00:13:12,631
All right.
Here we go.

310
00:13:12,632 --> 00:13:16,733
The first canister fully lived
up to its no-burn promise.

311
00:13:16,734 --> 00:13:17,867
So let's check the second.

312
00:13:21,104 --> 00:13:22,238
Bupkes.

313
00:13:22,239 --> 00:13:24,373
That's two quick strikes,

314
00:13:24,374 --> 00:13:26,808
But the third
shows some promise.

315
00:13:28,377 --> 00:13:29,710
Oh. Not bad.

316
00:13:29,711 --> 00:13:32,245
As for number 4,

317
00:13:32,246 --> 00:13:34,448
Just lay back and bask

318
00:13:34,449 --> 00:13:37,084
In the ambient heat
of the can that can.

319
00:13:37,085 --> 00:13:41,589
Whoa! Ho!
That's the money right there.

320
00:13:41,590 --> 00:13:43,558
Want to see it again?

321
00:13:43,559 --> 00:13:44,926
I think we all do.

322
00:13:48,730 --> 00:13:50,696
The key thing
that made this a fireball

323
00:13:50,697 --> 00:13:52,863
Was the kind of propellant
it used.

324
00:13:52,864 --> 00:13:55,131
So, on to can 5.

325
00:13:57,167 --> 00:14:00,836
Oh!
5 is a contender.

326
00:14:02,605 --> 00:14:05,073
As it turns out, at 6 inches,

327
00:14:05,074 --> 00:14:08,509
2 out of our 5 samples
were aggressively flammable.

328
00:14:08,510 --> 00:14:11,111
So they found
the two most volatile cans,

329
00:14:11,112 --> 00:14:14,013
But there's no guarantee
that either one will ignite

330
00:14:14,014 --> 00:14:16,049
When it's sprayed on a fabric.

331
00:14:16,050 --> 00:14:18,184
To test that, we will be staging

332
00:14:18,185 --> 00:14:21,887
The world's first
wet-flannel-shirt contest.

333
00:14:25,157 --> 00:14:27,024
We're back in the shop
because we found

334
00:14:27,025 --> 00:14:28,959
Even the most powerful
consumer fireworks

335
00:14:28,960 --> 00:14:30,761
We can get
in the entire United States

336
00:14:30,762 --> 00:14:33,230
Did not have the thrust
we need to propel a man.

337
00:14:33,231 --> 00:14:35,365
So, since this myth
originated in Europe,

338
00:14:35,366 --> 00:14:37,499
We're thinking
maybe they had something

339
00:14:37,500 --> 00:14:38,767
A little more powerful.

340
00:14:38,768 --> 00:14:40,868
Now, since we weren't able
to get

341
00:14:40,869 --> 00:14:43,704
The european skyrockets
with the greater thrust,

342
00:14:43,705 --> 00:14:45,472
We have to make our own rocket.

343
00:14:45,473 --> 00:14:47,575
So we have
the next-best thing --

344
00:14:47,576 --> 00:14:48,842
A model rocket motor.

345
00:14:48,843 --> 00:14:50,444
It has the same exact thrust.

346
00:14:50,445 --> 00:14:53,380
Now what we need to do is
add a cone, attach a stick,

347
00:14:53,381 --> 00:14:55,815
And maybe make them
look more like skyrockets.

348
00:14:55,816 --> 00:15:00,519
Things get off
to a slowish start...

349
00:15:00,520 --> 00:15:02,320
I've glued myself
to the rocket already.

350
00:15:02,321 --> 00:15:04,954
...As they set about
custom-building an arsenal

351
00:15:04,955 --> 00:15:08,423
Of european-strength
single-stage skyrockets.

352
00:15:08,424 --> 00:15:11,963
We pride ourselves on quantity,
not quality.

353
00:15:11,964 --> 00:15:13,731
Let's hope he's joking,

354
00:15:13,732 --> 00:15:16,534
Because all these
homemade fireworks

355
00:15:16,535 --> 00:15:19,002
Have to be just as reliable
as the store-bought ones.

356
00:15:19,003 --> 00:15:20,403
That's it.

357
00:15:20,404 --> 00:15:22,638
If I won a pageant, this would
definitely be my bouquet.

358
00:15:22,639 --> 00:15:24,272
Those look awesome.

359
00:15:24,273 --> 00:15:26,373
All right. You guys ready
to set them off?

360
00:15:26,374 --> 00:15:29,576
Yeah.
Oh, yeah, definitely.

361
00:15:29,577 --> 00:15:31,944
So it's back to the
bomb range with nothing to prove.

362
00:15:31,945 --> 00:15:33,779
Yeah, I got high hopes.

363
00:15:33,780 --> 00:15:37,015
If these rockets can't bear
a much bigger load,

364
00:15:37,016 --> 00:15:39,017
The myth is as good as busted.

365
00:15:39,018 --> 00:15:41,519
All right, so our first test
is gonna be our control.

366
00:15:41,520 --> 00:15:45,022
This is our new and improved
rockets with no weights.

367
00:15:45,023 --> 00:15:47,324
We'll find out
how fast they go.

368
00:15:47,325 --> 00:15:49,192
This time,
they've hooked up the rocket

369
00:15:49,193 --> 00:15:51,661
To a much safer electric fuse,

370
00:15:51,662 --> 00:15:54,497
And Kari's about to show
how she responds

371
00:15:54,498 --> 00:15:56,265
In a moment of pure panic.

372
00:15:56,266 --> 00:15:58,900
In 3, 2, 1.

373
00:16:02,771 --> 00:16:03,938
Okay.

374
00:16:03,939 --> 00:16:05,806
The skyrocket turned kamikaze,

375
00:16:05,807 --> 00:16:08,709
But it stayed straight enough
for long enough

376
00:16:08,710 --> 00:16:10,577
To get the data --

377
00:16:10,578 --> 00:16:13,279
96 miles per hour
at the top of the scale.

378
00:16:13,280 --> 00:16:15,614
I also learned something
very valuable, which is,

379
00:16:15,615 --> 00:16:16,915
When in peril,

380
00:16:16,916 --> 00:16:19,751
I will use one of my co-workers
as a human shield.

381
00:16:19,752 --> 00:16:22,053
Sorry, Grant.

382
00:16:22,054 --> 00:16:24,155
But Grant remains unfazed.

383
00:16:24,156 --> 00:16:25,323
He's already decided

384
00:16:25,324 --> 00:16:27,992
They can afford
to up the starting weight.

385
00:16:27,993 --> 00:16:30,994
So, I think we can go
directly to the 150-gram load,

386
00:16:30,995 --> 00:16:33,430
Which is exactly what
the consumer-grade firework

387
00:16:33,431 --> 00:16:35,865
Could do for its
maximum capacity.

388
00:16:35,866 --> 00:16:38,768
By adding
small weights to single rockets,

389
00:16:38,769 --> 00:16:41,604
They hope to find out
if 400 fireworks

390
00:16:41,605 --> 00:16:43,706
Really could launch a human.

391
00:16:43,707 --> 00:16:46,207
In 3...2...1.

392
00:16:48,310 --> 00:16:49,577
Whoo-hoo-hoo!

393
00:16:49,578 --> 00:16:51,245
Wow!

394
00:16:51,246 --> 00:16:53,547
It's gone.

395
00:16:53,548 --> 00:16:56,884
I don't think that weight
did a whole lot.

396
00:16:56,885 --> 00:16:59,520
That weight didn't do anything.

397
00:16:59,521 --> 00:17:00,988
Actually, it did.

398
00:17:00,989 --> 00:17:04,123
But the homemade rocket bore
its burden with relative ease.

399
00:17:04,124 --> 00:17:04,223
Nice.

400
00:17:04,224 --> 00:17:05,357
But the homemade rocket bore
its burden with relative ease.

401
00:17:05,358 --> 00:17:07,359
That's crazy.

402
00:17:07,360 --> 00:17:10,728
All right. That is 53 miles
per hour, so not even 50% yet.

403
00:17:10,729 --> 00:17:12,363
Well,
I'd also like to point out

404
00:17:12,364 --> 00:17:14,265
That the commercial ones
that we were using before

405
00:17:14,266 --> 00:17:16,968
Looked like they were slowing when
they got to the top of the scale.

406
00:17:16,969 --> 00:17:19,237
These have way more thrust. I
think we can double the weight.

407
00:17:19,238 --> 00:17:21,873
All right. Let's take it
up to 300 grams.

408
00:17:21,874 --> 00:17:23,107
All right.

409
00:17:23,108 --> 00:17:25,140
So Tory glues six nuts

410
00:17:25,141 --> 00:17:28,139
To the top of the cone
of the next skyrocket.

411
00:17:28,140 --> 00:17:33,444
This seem dangerous to launch
300 grams of steel into the air?

412
00:17:33,445 --> 00:17:37,112
Well, given the flight
path of the first rocket, yeah.

413
00:17:38,615 --> 00:17:42,216
In 3...2...1.

414
00:17:44,518 --> 00:17:46,285
Nice.

415
00:17:46,286 --> 00:17:47,687
It lifted it.

416
00:17:47,688 --> 00:17:51,625
Great.
Let's see how fast it went.

417
00:17:51,626 --> 00:17:53,261
The high-speed confirms

418
00:17:53,262 --> 00:17:55,129
They've honed in
on the goldilocks figure

419
00:17:55,130 --> 00:17:56,964
For weight-bearing rockets.

420
00:17:56,965 --> 00:17:58,665
- That is cool.
- Wow.

421
00:17:58,666 --> 00:18:02,035
All right. And that is
43 miles per hour.

422
00:18:02,036 --> 00:18:03,770
And that's pretty impressive.

423
00:18:03,771 --> 00:18:05,604
Yeah, but it is slowing
at the end of the line,

424
00:18:05,605 --> 00:18:08,240
So I think we're gonna have
to call this the limit,

425
00:18:08,241 --> 00:18:10,342
The carrying capacity for
the rocket motor.

426
00:18:10,576 --> 00:18:12,010
Okay, with 300 grams added
to what is already 100 grams for the rocket.

427
00:18:12,011 --> 00:18:14,145
That means we're going to have to have

428
00:18:16,848 --> 00:18:17,081
about 400 rockets to get our
man off the ground.

429
00:18:18,650 --> 00:18:20,784
That gives validity to this myth.

430
00:18:20,785 --> 00:18:23,187
All right.
Guess we got to get building.

431
00:18:23,188 --> 00:18:24,922
Cool.
God, that's awesome.

432
00:18:24,923 --> 00:18:27,857
So, the myth
of the fireworks man

433
00:18:27,858 --> 00:18:29,358
Is alive and kicking.

434
00:18:29,359 --> 00:18:32,794
They just need to put
all that potency into practice.

435
00:18:39,240 --> 00:18:40,541
Well, so far, so good.

436
00:18:40,542 --> 00:18:42,409
Yep, stun guns do provide

437
00:18:42,410 --> 00:18:44,778
A very reasonable spark
for ignition,

438
00:18:44,779 --> 00:18:47,347
And some pepper sprays
are quite flammable.

439
00:18:47,348 --> 00:18:49,048
So now all we got to do
is put the two together

440
00:18:49,049 --> 00:18:52,285
And see if we get some kind
of spontaneous combustion.

441
00:18:52,286 --> 00:18:53,720
Slow down there, cowboy.

442
00:18:53,721 --> 00:18:56,323
I think there's one more thing
we could take a look at in here,

443
00:18:56,324 --> 00:18:57,724
Which is what kind of material

444
00:18:57,725 --> 00:18:59,758
Was the shirt made of
that the perp was wearing?

445
00:18:59,759 --> 00:19:01,760
There's a lot
of different things

446
00:19:01,761 --> 00:19:03,594
They make clothing out of,

447
00:19:03,595 --> 00:19:05,396
And some are more flammable
than others.

448
00:19:05,397 --> 00:19:07,398
I think we need to do some tests
and find out

449
00:19:07,399 --> 00:19:09,866
Which kind of material we can
find that burns the fastest.

450
00:19:09,867 --> 00:19:11,935
Okay.

451
00:19:11,936 --> 00:19:13,903
Armed with a lighter

452
00:19:13,904 --> 00:19:16,205
And a charming selection
of swatches,

453
00:19:16,206 --> 00:19:18,040
The method is
pretty straightforward.

454
00:19:18,041 --> 00:19:20,008
Fabric placed
on a 45-degree angle,

455
00:19:20,009 --> 00:19:22,643
Exposed to a lighter
at the bottom for one second

456
00:19:22,644 --> 00:19:26,713
And timed how long it takes
for the flame to reach the top.

457
00:19:26,714 --> 00:19:28,347
We compare all these
and figure out

458
00:19:28,348 --> 00:19:30,149
Which one's the most flammable.

459
00:19:30,150 --> 00:19:31,183
I like it.

460
00:19:31,184 --> 00:19:33,618
The guy on "CSI"
to get set on fire

461
00:19:33,619 --> 00:19:35,386
Was wearing a flannel shirt.

462
00:19:35,387 --> 00:19:36,520
Now, what is flannel?

463
00:19:36,521 --> 00:19:39,523
Well, in the early days,
it was a wool material.

464
00:19:39,524 --> 00:19:41,424
Then it was a wool blend.

465
00:19:41,425 --> 00:19:44,127
Now it can be virtually
any kind of material

466
00:19:44,128 --> 00:19:47,497
That is thick and sort of Fluffy
and has this plaid pattern.

467
00:19:47,498 --> 00:19:48,964
So, from natural fibers...

468
00:19:48,965 --> 00:19:50,399
Here comes cotton.

469
00:19:50,400 --> 00:19:52,134
...To acrylics and acetates,

470
00:19:52,135 --> 00:19:56,237
The guys put the torch to some
hopefully flammable fabrics.

471
00:19:56,238 --> 00:19:59,106
All right.
Let's try rayon.

472
00:19:59,107 --> 00:20:01,475
Some take their own sweet time.

473
00:20:01,476 --> 00:20:03,678
45 seconds.

474
00:20:03,679 --> 00:20:05,245
And that's it.

475
00:20:05,246 --> 00:20:07,747
Some just refuse to catch fire.

476
00:20:07,748 --> 00:20:12,251
No burning at all from wool.

477
00:20:12,252 --> 00:20:15,320
And others burn up
like a trail of gunpowder.

478
00:20:15,321 --> 00:20:19,924
Dude.
Fleece burns with vigor.

479
00:20:19,925 --> 00:20:23,261
Bang. That's it right there.
15 seconds.

480
00:20:23,262 --> 00:20:26,297
Now all that remains
is to find out the fastest.

481
00:20:26,298 --> 00:20:28,332
The results are in.

482
00:20:28,333 --> 00:20:30,534
We have burned
eight kinds of fabric,

483
00:20:30,535 --> 00:20:32,569
Gotten eight
different burn times,

484
00:20:32,570 --> 00:20:35,537
And the winner, it turns out,
is a tie at 15 seconds.

485
00:20:35,538 --> 00:20:39,907
The fastest-burning fabrics
are both acrylic and fleece.

486
00:20:39,908 --> 00:20:42,143
Robert,
tell them what they've won.

487
00:20:42,144 --> 00:20:43,410
Thanks, Adam.

488
00:20:43,411 --> 00:20:45,845
Yes, today's two fabrics
both win the chance

489
00:20:45,846 --> 00:20:47,947
To return to the game
as real shirts,

490
00:20:47,948 --> 00:20:50,349
Then get burned
right down to their buttons

491
00:20:50,350 --> 00:20:52,151
In a winner-takes-all
torch time trial.

492
00:20:52,152 --> 00:20:53,585
Back to you, Adam.

493
00:20:53,586 --> 00:20:57,422
In order to do that, I'm going
to call upon all the skills

494
00:20:57,423 --> 00:21:00,525
I remember from home economics
in 4th and 5th grade

495
00:21:00,526 --> 00:21:02,026
With Miss Cavinitis.

496
00:21:02,027 --> 00:21:04,328
I still remember
a couple things.

497
00:21:04,329 --> 00:21:06,129
Adam's not showing off.

498
00:21:06,130 --> 00:21:09,165
We just couldn't buy
a plaid fleece shirt.

499
00:21:09,166 --> 00:21:11,867
So this is a home-spun
savage original.

500
00:21:11,868 --> 00:21:15,637
But he will need some torsos
to hang his designs on.

501
00:21:15,638 --> 00:21:18,205
That's where this guy comes in,
because I'm going to make

502
00:21:18,206 --> 00:21:20,574
A wire mannequin
that looks roughly like this

503
00:21:20,575 --> 00:21:23,276
So we have something
to hang them on while they burn.

504
00:21:23,277 --> 00:21:25,478
In just a few minutes,

505
00:21:25,479 --> 00:21:28,047
They both finish flirting
with fashion,

506
00:21:28,048 --> 00:21:31,049
And they both seem enamored
with their efforts.

507
00:21:33,352 --> 00:21:34,619
Show Jamie my threads.

508
00:21:34,620 --> 00:21:36,922
Check it out.

509
00:21:36,923 --> 00:21:39,091
Uh, who's your tailor, dude?

510
00:21:39,092 --> 00:21:42,060
I am my tailor.

511
00:21:42,061 --> 00:21:44,761
Hey, these
are one-time use.

512
00:21:44,762 --> 00:21:46,729
These guys look great.

513
00:21:46,730 --> 00:21:49,664
Meet Bernie and his
little brother, Crispin.

514
00:21:49,665 --> 00:21:52,698
So Bernie and Crispin
get shirted up --

515
00:21:52,699 --> 00:21:55,633
One with a plaid
that's all acrylic

516
00:21:55,634 --> 00:21:57,835
And the other made
from so-called fleece,

517
00:21:57,836 --> 00:22:01,639
Another synthetic that's partly
made from recycled plastic.

518
00:22:01,640 --> 00:22:07,043
The boys are eager to learn just
how combustible a shirt can be.

519
00:22:07,044 --> 00:22:10,479
Both shirts are lit from the
same point at the same time.

520
00:22:10,480 --> 00:22:11,981
All right, now,
the acrylic really seems

521
00:22:11,982 --> 00:22:13,550
To be winning by a fair bit.

522
00:22:13,551 --> 00:22:15,920
It's much more aggressive.

523
00:22:15,921 --> 00:22:17,722
Indeed.

524
00:22:17,723 --> 00:22:19,090
With no pepper spray,

525
00:22:19,091 --> 00:22:22,093
Both shirts burn slowly
but consistently.

526
00:22:22,094 --> 00:22:25,429
Adam, of course,
has a vested interest.

527
00:22:25,430 --> 00:22:27,430
Come on, fleece --
after all our training,

528
00:22:27,431 --> 00:22:29,399
After all our discussion,
is that all you got?

529
00:22:29,400 --> 00:22:31,300
You're gonna let acrylic
take you to town?

530
00:22:31,301 --> 00:22:32,768
You're gonna let him
show you up?

531
00:22:32,769 --> 00:22:34,069
Put something into it, man.

532
00:22:34,070 --> 00:22:35,971
But he's backed
the wrong blouse.

533
00:22:35,972 --> 00:22:40,307
Eventually, the acrylic is the
first one to give up the ghost.

534
00:22:40,308 --> 00:22:41,575
I'm gonna call it.

535
00:22:41,576 --> 00:22:44,744
8:25 --

536
00:22:44,745 --> 00:22:46,978
The acrylic is
completely burnt up,

537
00:22:46,979 --> 00:22:48,880
To a crisp,

538
00:22:48,881 --> 00:22:52,449
And the fleece still has
more than halfway to go.

539
00:22:52,450 --> 00:22:53,750
Yep.

540
00:22:53,751 --> 00:22:56,686
So, acrylic it is,
and here's the upshot.

541
00:22:56,687 --> 00:23:01,790
Shirts do burn, stun guns
can make a big spark,

542
00:23:01,791 --> 00:23:04,293
And some pepper sprays
are totally flammable.

543
00:23:04,294 --> 00:23:05,927
Now all that remains

544
00:23:05,928 --> 00:23:08,363
Is to pull these best-case
combustibles together

545
00:23:08,364 --> 00:23:10,364
To see if they can really make

546
00:23:10,365 --> 00:23:13,534
That instantaneous
human fireball.

547
00:23:16,130 --> 00:23:18,264
Don't try anything you've seen
on this show at home.

548
00:23:18,265 --> 00:23:19,632
We are what you call...
Experts.

549
00:23:24,048 --> 00:23:25,716
All right, so,
according to the tests,

550
00:23:25,717 --> 00:23:27,550
We are gonna need a lot
of these fireworks

551
00:23:27,551 --> 00:23:29,418
To get this guy off the ground.

552
00:23:29,419 --> 00:23:31,988
But the toughest part is
getting all those rockets

553
00:23:31,989 --> 00:23:33,122
To ignite at the same time.

554
00:23:33,123 --> 00:23:34,456
And how were they
attached to him?

555
00:23:34,457 --> 00:23:35,891
What kind of rig are we
talking about here?

556
00:23:35,892 --> 00:23:37,526
Again, the details are vague.

557
00:23:37,527 --> 00:23:39,895
We do know that he launched
himself off a ramp,

558
00:23:39,896 --> 00:23:41,697
But there's
no other information.

559
00:23:41,698 --> 00:23:43,966
All right. Well, then,
why don't we do this?

560
00:23:43,967 --> 00:23:46,034
We'll each come up with our own
design, small-scale,

561
00:23:46,035 --> 00:23:47,569
We'll attach
an action figure to it,

562
00:23:47,570 --> 00:23:48,803
And we'll launch him
off the ramp,

563
00:23:48,804 --> 00:23:50,436
And we'll see which one
has the best launch

564
00:23:50,437 --> 00:23:52,069
And which one has
the best flight pattern.

565
00:23:52,070 --> 00:23:54,271
So, in this workshop arena,

566
00:23:54,272 --> 00:23:57,440
Three specialist craftsmen
go head-to-head.

567
00:24:02,245 --> 00:24:06,048
They have just one hour
to whip up a workable prototype.

568
00:24:06,049 --> 00:24:09,585
So, let the games begin.

569
00:24:09,586 --> 00:24:11,953
Each contestant gets
two basic ingredients --

570
00:24:11,954 --> 00:24:16,758
One raw mini-buster
and one sprig of skyrockets.

571
00:24:16,759 --> 00:24:18,593
The winning design is the one

572
00:24:18,594 --> 00:24:21,629
That can best launch the doll
from a miniature ramp.

573
00:24:21,630 --> 00:24:24,532
Okay, so, my idea is

574
00:24:24,533 --> 00:24:27,532
A giant christmas-tree-shaped
fireworks cluster.

575
00:24:27,533 --> 00:24:30,232
I mean, what is more directional
than an arrow, huh?

576
00:24:30,233 --> 00:24:33,101
So all the thrust is
gonna go down this way,

577
00:24:33,102 --> 00:24:36,003
And the guy's gonna go...
Whoosh...Straight out.

578
00:24:36,004 --> 00:24:38,505
The only problem is making sure

579
00:24:38,506 --> 00:24:41,473
That the exhaust
from all the fireworks

580
00:24:41,474 --> 00:24:42,774
Doesn't burn him to a crisp.

581
00:24:42,775 --> 00:24:44,443
I'll work that out later.

582
00:24:44,444 --> 00:24:46,544
Yeah. Good luck with that.

583
00:24:46,545 --> 00:24:47,645
Meantime...

584
00:24:47,646 --> 00:24:49,012
That's the outfit.

585
00:24:49,013 --> 00:24:51,481
Now, my design for fireworks man
is very simple.

586
00:24:51,482 --> 00:24:53,449
It's basically taking
a set of wings

587
00:24:53,450 --> 00:24:55,017
And attaching them to his back.

588
00:24:55,018 --> 00:24:57,586
And then down the wing,
I'll be attaching rockets.

589
00:24:57,587 --> 00:25:00,921
And when I launch that off,
hopefully it'll act like a jet.

590
00:25:00,922 --> 00:25:03,856
Only thing is I hope these guys
can keep up with my pace.

591
00:25:03,857 --> 00:25:06,425
But we still
haven't heard from Kari.

592
00:25:06,426 --> 00:25:08,391
Essentially, this is my design.

593
00:25:08,392 --> 00:25:10,292
We have rockets
shooting out the back,

594
00:25:10,293 --> 00:25:11,660
A big wing for stabilization,

595
00:25:11,661 --> 00:25:13,929
Comfortable pillow
for my guy to lay on,

596
00:25:13,930 --> 00:25:15,664
And a skateboard

597
00:25:15,665 --> 00:25:17,866
That's going to reduce
the resistance up the ramp.

598
00:25:17,867 --> 00:25:19,302
Now, I think the best part
of my design

599
00:25:19,303 --> 00:25:20,573
Is that I've created a flashpan

600
00:25:20,574 --> 00:25:22,711
That's going to ignite
all of my rockets at once,

601
00:25:22,712 --> 00:25:24,615
Because simultaneous ignition
is something

602
00:25:24,616 --> 00:25:27,652
That we've always had trouble
with on "Mythbusters."

603
00:25:27,653 --> 00:25:30,088
While Kari and Grant
push on with their plans,

604
00:25:30,089 --> 00:25:33,791
There's been a small sensation
over at team Tory.

605
00:25:33,792 --> 00:25:37,258
He's decided to scrap his design
and go with a new one.

606
00:25:37,259 --> 00:25:40,593
I really wish that I had
come up with Tory's design

607
00:25:40,594 --> 00:25:43,193
Just 'cause
I'm a big "Star Wars" fan

608
00:25:43,194 --> 00:25:44,961
And it looks just like
an X-wing fighter.

609
00:25:44,962 --> 00:25:46,797
I know it was a little late
in the game

610
00:25:46,798 --> 00:25:48,565
To change the design
of firework man,

611
00:25:48,566 --> 00:25:52,602
But, you know...I think
this design is much better.

612
00:25:52,603 --> 00:25:53,936
The hour is up,

613
00:25:53,937 --> 00:25:55,971
And these
radically different designs

614
00:25:55,972 --> 00:25:57,606
Are about to be put to the test.

615
00:25:57,607 --> 00:26:01,143
3, 2, 1, and stop.

616
00:26:01,144 --> 00:26:03,678
Done.
Done.

617
00:26:03,679 --> 00:26:05,279
Let's see them.

618
00:26:05,280 --> 00:26:06,413
All right.

619
00:26:08,883 --> 00:26:11,651
Oh, are you ready to put your
rockets where your mouth is?

620
00:26:11,652 --> 00:26:13,185
Bring it.
Let's launch them.

621
00:26:13,186 --> 00:26:15,787
All right.
Get ready to lose, you guys.

622
00:26:15,788 --> 00:26:17,121
Just like Adam and Jamie,

623
00:26:17,122 --> 00:26:18,589
They're testing
at treasure island

624
00:26:18,590 --> 00:26:20,190
Under the Bay bridge.

625
00:26:20,191 --> 00:26:22,458
They're aiming to see
which design

626
00:26:22,459 --> 00:26:23,793
Has the best flight path

627
00:26:23,794 --> 00:26:25,995
And which one
flies the farthest.

628
00:26:25,996 --> 00:26:28,930
For that, they'll need
to stake out their turf.

629
00:26:28,931 --> 00:26:31,832
That might be
a little presumptuous.

630
00:26:31,833 --> 00:26:34,434
Given the strength
of the mini rockets,

631
00:26:34,435 --> 00:26:37,703
200 feet might be
a tad optimistic.

632
00:26:37,704 --> 00:26:40,005
Now, for that occur,
two things have to happen.

633
00:26:40,006 --> 00:26:43,374
One, we have to have
straight and stable flight.

634
00:26:43,375 --> 00:26:46,646
Two, we have to not explode
on the launch pad.

635
00:26:46,647 --> 00:26:49,448
Two very good points.

636
00:26:49,449 --> 00:26:51,650
And Tory's the first
to test his luck.

637
00:26:51,651 --> 00:26:54,586
I have trays of black powder
at each bundle of fireworks.

638
00:26:54,587 --> 00:26:56,387
I'm using an electric ignitor
to light off

639
00:26:56,388 --> 00:26:58,755
Each of those trays
of black powder.

640
00:26:58,756 --> 00:27:01,123
Once I hit the button,
all rockets should fire

641
00:27:01,124 --> 00:27:03,092
At the exact same time.

642
00:27:03,093 --> 00:27:05,727
In 3, 2, 1.

643
00:27:05,728 --> 00:27:07,862
- Whoo!
- Wow!

644
00:27:07,863 --> 00:27:09,630
It did something.

645
00:27:09,631 --> 00:27:12,933
I think it exploded
on the launch pad.

646
00:27:12,934 --> 00:27:15,869
The x-wing aircraft
went pretty much nowhere.

647
00:27:15,870 --> 00:27:19,339
But the pilot covered some
fair piece of real estate.

648
00:27:19,340 --> 00:27:21,641
Tory's launch was awesome,

649
00:27:21,642 --> 00:27:24,810
Mostly because I can't
even tell what happened.

650
00:27:24,811 --> 00:27:27,779
And the guy ended up
with his butt burned up

651
00:27:27,780 --> 00:27:31,082
Over on the lawn in a totally
different direction.

652
00:27:31,083 --> 00:27:34,018
Now, there's a piece
of my fireworks rocket.

653
00:27:34,019 --> 00:27:36,353
There's another piece.
Talk about epic fail.

654
00:27:36,354 --> 00:27:41,123
Not only did it crash and burn,
it exploded into pieces.

655
00:27:41,124 --> 00:27:43,892
Time for the next
fledgling to test her wings.

656
00:27:43,893 --> 00:27:46,494
But it's Grant
who makes the prediction.

657
00:27:46,495 --> 00:27:49,697
And if you pick up
her "flight vehicle,"

658
00:27:49,698 --> 00:27:52,300
It's a little back-heavy,
actually.

659
00:27:52,301 --> 00:27:55,937
So it could end up
sort of doing --

660
00:27:55,938 --> 00:27:57,672
I think it's actually gonna do
a loop-the-loop,

661
00:27:57,673 --> 00:27:59,607
As a matter of fact.

662
00:28:00,742 --> 00:28:02,876
Hold on, little missy.

663
00:28:02,877 --> 00:28:08,179
Fireworks man, Kari design,
small-scale, in 3, 2, 1.

664
00:28:09,181 --> 00:28:12,282
Holy...Wow!
Whoa.

665
00:28:12,283 --> 00:28:14,717
Whoo-hoo!

666
00:28:16,953 --> 00:28:18,519
Well, if we wanted something

667
00:28:18,520 --> 00:28:20,954
To go across the surface
really quickly,

668
00:28:20,955 --> 00:28:21,954
We got it.

669
00:28:21,955 --> 00:28:24,290
That was spectacular.
Oh, my God.

670
00:28:24,291 --> 00:28:27,830
It didn't fly high,
but it did fly straight,

671
00:28:27,831 --> 00:28:32,068
And every bit of that unlikely
apparatus left the ramp.

672
00:28:32,069 --> 00:28:35,204
As for the added sparkles,
nice touch.

673
00:28:35,205 --> 00:28:37,039
My guy isn't charred.

674
00:28:37,040 --> 00:28:38,840
We had a perfect ignition.

675
00:28:38,841 --> 00:28:41,643
We had a pretty good distance.

676
00:28:41,644 --> 00:28:43,077
So maybe if I had longer wings,

677
00:28:43,078 --> 00:28:45,079
This would have been
a perfect flight.

678
00:28:45,080 --> 00:28:47,814
I think I might actually have
the winning design here.

679
00:28:47,815 --> 00:28:51,017
But we're yet to see
Grant's design take to the air,

680
00:28:51,018 --> 00:28:53,752
And he's suffering
from preflight nerves.

681
00:28:53,753 --> 00:28:56,387
Okay. Here's my biggest fear.

682
00:28:56,388 --> 00:28:58,655
Instead of going on
this nice ballistic trajectory

683
00:28:58,656 --> 00:28:59,923
Out that way,

684
00:28:59,924 --> 00:29:02,292
It goes...Whoosh, sss...

685
00:29:02,293 --> 00:29:04,893
And comes right back at us.

686
00:29:04,894 --> 00:29:08,266
If I see that happen,
I'm hitting the deck.

687
00:29:08,267 --> 00:29:10,334
Okay. Good luck.

688
00:29:10,335 --> 00:29:12,102
When even the experts
are scared,

689
00:29:12,103 --> 00:29:15,805
It's probably wise
to duck and cover.

690
00:29:15,806 --> 00:29:18,240
In 3, 2, 1.

691
00:29:23,412 --> 00:29:25,912
Grant's launch looked

692
00:29:25,913 --> 00:29:28,347
More like a guy
slipping on soap.

693
00:29:28,348 --> 00:29:29,681
Whoa!

694
00:29:29,682 --> 00:29:32,416
So there's no real need
for a high-speed replay.

695
00:29:32,417 --> 00:29:33,717
But let's do it anyway.

696
00:29:33,718 --> 00:29:34,252
This one barely mad

697
00:29:34,253 --> 00:29:37,457
It but let's do it anyway.
Off the launch pad,

698
00:29:37,458 --> 00:29:38,992
Did not achieve flight,

699
00:29:38,993 --> 00:29:41,429
Could not get
simultaneous ignition,

700
00:29:41,430 --> 00:29:43,398
And, therefore,
has to be rejected.

701
00:29:43,399 --> 00:29:46,433
Whoo! Ohh!

702
00:29:46,434 --> 00:29:48,702
So the winning design
is clearly Kari's.

703
00:29:48,703 --> 00:29:52,172
In the end, this is
the design we're going with.

704
00:29:52,173 --> 00:29:55,308
We have one bank of fireworks
that all ignite simultaneously.

705
00:29:55,309 --> 00:29:56,875
We have a heat shield

706
00:29:56,876 --> 00:29:58,809
That keeps our little driver
from getting fried.

707
00:29:58,810 --> 00:30:00,644
And the wing created
enough stability

708
00:30:00,645 --> 00:30:02,246
To get us a nice, short flight.

709
00:30:02,247 --> 00:30:04,882
Now, I think if we increase
the length of the wing,

710
00:30:04,883 --> 00:30:09,286
We'll get more stability and
maybe get a perfect trajectory.

711
00:30:16,932 --> 00:30:19,084
After days of experimentation,

712
00:30:19,085 --> 00:30:21,952
Adam and Jamie are finally ready
to test the myth

713
00:30:21,953 --> 00:30:24,822
Of the "CSI" stun gun.

714
00:30:25,454 --> 00:30:27,921
This fine specimen
of manhood here

715
00:30:27,922 --> 00:30:30,756
Will soon be our perp
for our final test.

716
00:30:30,757 --> 00:30:32,524
Now, in order to be
a proper perp,

717
00:30:32,525 --> 00:30:34,259
I needed to have
conductive skin.

718
00:30:34,260 --> 00:30:37,662
So I'm gonna give him
a layer of foam,

719
00:30:37,663 --> 00:30:39,964
And then I'm going to cover
that foam with foil,

720
00:30:39,965 --> 00:30:42,366
And that foil will act
as the conductive skin

721
00:30:42,367 --> 00:30:43,934
That hopefully will give us
the spark

722
00:30:43,935 --> 00:30:46,135
To light our perp on fire.

723
00:30:46,136 --> 00:30:48,671
He's ready.

724
00:30:48,672 --> 00:30:51,639
And in hope
of a blazing conclusion,

725
00:30:51,640 --> 00:30:53,474
It's back to treasure island.

726
00:30:53,475 --> 00:30:55,241
The methodology here is
actually pretty simple.

727
00:30:55,242 --> 00:30:57,909
Our perp here is dressed
in the latest fashion --

728
00:30:57,910 --> 00:31:00,778
The acrylic shirt that we found
the most flammable.

729
00:31:00,779 --> 00:31:02,646
We are going to spray him down

730
00:31:02,647 --> 00:31:05,282
With the pepper spray we found
most flammable -- number 4.

731
00:31:05,283 --> 00:31:08,051
And then I am going to stand
back with this stun gun...

732
00:31:09,053 --> 00:31:10,554
...And pop him
right in the chest

733
00:31:10,555 --> 00:31:13,124
And see if he bursts
into flames.

734
00:31:13,125 --> 00:31:14,625
All right.
Stand clear.

735
00:31:14,626 --> 00:31:16,626
So, confirming the myth

736
00:31:16,627 --> 00:31:18,594
Of an instant, massive fireball

737
00:31:18,595 --> 00:31:21,163
All comes down to this.

738
00:31:21,164 --> 00:31:23,432
Just like they did on "CSI,"

739
00:31:23,433 --> 00:31:25,333
Adam unloads
for a good few seconds.

740
00:31:25,334 --> 00:31:27,435
Freeze!

741
00:31:28,837 --> 00:31:32,339
Hey!

742
00:31:32,340 --> 00:31:35,441
Dude!
It's burning.

743
00:31:35,442 --> 00:31:39,545
I totally -- wow!
He's totally burning.

744
00:31:40,714 --> 00:31:43,915
And we totally need
the fire extinguisher.

745
00:31:46,117 --> 00:31:48,652
You have the right
to not be on fire.

746
00:31:48,653 --> 00:31:49,886
Anything you burn

747
00:31:49,887 --> 00:31:52,722
Can and will be held against you
in a court of law.

748
00:31:52,723 --> 00:31:55,891
But do we have the right
to call this confirmed?

749
00:31:55,892 --> 00:31:59,093
Of course, it wasn't
quite the big fireball

750
00:31:59,094 --> 00:32:00,495
That we saw on "CSI."

751
00:32:00,496 --> 00:32:02,797
* I'm on fire *

752
00:32:02,798 --> 00:32:04,364
But this being "Mythbusters,"

753
00:32:04,365 --> 00:32:06,733
We're gonna do our darndest
to get one.

754
00:32:06,734 --> 00:32:09,235
So they postpone the judgment,

755
00:32:09,236 --> 00:32:13,338
Discharging four whole cans
on a backup acrylic shirt.

756
00:32:13,339 --> 00:32:15,841
Think that's enough?
No.

757
00:32:17,177 --> 00:32:22,446
Just for good measure,
Jamie almost doubles the dose.

758
00:32:22,447 --> 00:32:25,048
All right.

759
00:32:25,049 --> 00:32:26,482
Freeze!

760
00:32:28,819 --> 00:32:30,586
Nice!

761
00:32:30,587 --> 00:32:33,288
Yeah.

762
00:32:33,289 --> 00:32:34,956
Now that's really close

763
00:32:34,957 --> 00:32:37,857
To the human bonfire
we saw on tv.

764
00:32:37,858 --> 00:32:38,958
There's your fireball.

765
00:32:40,794 --> 00:32:43,663
It's instantaneous.
Look at that.

766
00:32:43,664 --> 00:32:46,633
Yeah. Might as well have lit it
with a match.

767
00:32:46,634 --> 00:32:48,002
Unbelievable.

768
00:32:48,003 --> 00:32:50,571
It's a fabulous fireball,

769
00:32:50,572 --> 00:32:55,075
But in this case, they did use
an ocean of pepper spray.

770
00:32:57,278 --> 00:32:59,044
So, how do we want
to call this one?

771
00:32:59,045 --> 00:33:00,445
Well, let's do a little math.

772
00:33:00,446 --> 00:33:04,548
One acrylic shirt plus a can
of flammable pepper spray

773
00:33:04,549 --> 00:33:07,117
Plus one stun gun equals...

774
00:33:07,118 --> 00:33:08,551
Plausible.

775
00:33:08,552 --> 00:33:09,686
I agree.

776
00:33:09,687 --> 00:33:11,188
One acrylic shirt
plus a stun gun

777
00:33:11,189 --> 00:33:14,457
Plus a whole crapload
of pepper spray equals...

778
00:33:14,458 --> 00:33:16,025
Gratuitous.

779
00:33:16,026 --> 00:33:18,126
That's our favorite
four-syllable word.

780
00:33:18,127 --> 00:33:20,430
So the verdict on this myth
is plausible.

781
00:33:20,431 --> 00:33:22,365
But we're not done yet.

782
00:33:22,366 --> 00:33:25,601
Jamie's determined to end
with a serious spectacle.

783
00:33:25,602 --> 00:33:28,203
And believe me,
you don't want to miss this.

784
00:33:30,000 --> 00:33:36,074
Everyone is intimidated by a shark. Become
a Card Shark AMERICASCARDROOM.COM

785
00:33:37,278 --> 00:33:38,812
Okay, so,
we're back in the shop

786
00:33:38,813 --> 00:33:40,346
After our
small-scale experiment.

787
00:33:40,347 --> 00:33:42,648
The myth that we're testing
is that some crazy German

788
00:33:42,649 --> 00:33:46,119
Thought it was a great idea to
strap 400 fireworks to himself,

789
00:33:46,120 --> 00:33:48,721
Propel himself off a ramp
into a lake.

790
00:33:48,722 --> 00:33:51,790
So, it is gonna take 400
of our homemade skyrockets

791
00:33:51,791 --> 00:33:53,692
To launch our fireworks man.

792
00:33:53,693 --> 00:33:55,862
Now the big challenge
of this design

793
00:33:55,863 --> 00:33:57,730
Is to attach all 400 together

794
00:33:57,731 --> 00:34:01,367
And to get them to go off
at the same exact time.

795
00:34:01,368 --> 00:34:03,468
And I'll be attaching
a new and improved wing design

796
00:34:03,469 --> 00:34:06,337
Which should help with the one
flaw from my small-scale,

797
00:34:06,338 --> 00:34:09,440
Which is spinning
out of control.

798
00:34:09,441 --> 00:34:10,841
Whoo-hoo!
Whoo!

799
00:34:10,842 --> 00:34:12,576
And they figured the best way

800
00:34:12,577 --> 00:34:14,277
To minimize friction
on the ramp

801
00:34:14,278 --> 00:34:15,978
Is to hook two skateboards

802
00:34:15,979 --> 00:34:18,414
Up to a shiny,
slippery metal rail.

803
00:34:18,415 --> 00:34:20,583
I can't stop.

804
00:34:20,584 --> 00:34:22,084
Aah!

805
00:34:22,085 --> 00:34:23,319
Ohh.

806
00:34:23,320 --> 00:34:25,286
Are you okay?
Yes.

807
00:34:25,287 --> 00:34:26,721
Dude, you got to be careful.

808
00:34:28,191 --> 00:34:31,259
Now, why a skateboard, you ask?

809
00:34:31,260 --> 00:34:34,695
Well, this was
clearly not some sort

810
00:34:34,696 --> 00:34:36,396
Of highly engineered
NASA launch.

811
00:34:36,397 --> 00:34:39,265
This is a guy that strapped
a bunch of fireworks to himself.

812
00:34:39,266 --> 00:34:42,201
And if you're in that mind-set,
what are you gonna use?

813
00:34:42,202 --> 00:34:45,104
You're gonna use some
sort of fancy system?

814
00:34:45,105 --> 00:34:47,973
No. You're probably gonna use
a skateboard.

815
00:34:47,974 --> 00:34:51,008
Now, for the sled, I came
up with something interesting.

816
00:34:51,009 --> 00:34:53,510
A surfboard.
It serves two purposes.

817
00:34:53,511 --> 00:34:55,312
For one, it's really light.

818
00:34:55,313 --> 00:34:58,815
It's not gonna add a lot
of weight to our contraption.

819
00:34:58,816 --> 00:35:01,817
And number two --
we're launching, hopefully,

820
00:35:01,818 --> 00:35:03,052
All the way into a lake,

821
00:35:03,053 --> 00:35:04,753
And retrieving
all of our rockets

822
00:35:04,754 --> 00:35:07,255
Would be a pain in the butt
if our whole thing sank,

823
00:35:07,256 --> 00:35:09,757
So...It's made of styrofoam.

824
00:35:09,758 --> 00:35:11,591
This thing floats.

825
00:35:11,592 --> 00:35:15,262
So, while the team gets
very, very busy with the building --

826
00:35:15,263 --> 00:35:16,630
Kari with these new wings

827
00:35:16,631 --> 00:35:18,865
And Grant
with some stabilizing fins --

828
00:35:18,866 --> 00:35:21,634
Tory gets to play with fire.

829
00:35:21,635 --> 00:35:24,203
So, I've removed
the sticks from the skyrockets,

830
00:35:24,204 --> 00:35:26,839
And I've glued together
banks of 100.

831
00:35:26,840 --> 00:35:28,340
Now that they're
all glued together,

832
00:35:28,341 --> 00:35:30,208
What I'm gonna do is cut grooves
on the table saw

833
00:35:30,209 --> 00:35:31,709
Through the nozzle area.

834
00:35:31,710 --> 00:35:35,713
That way, these grooves will be
filled up with black powder.

835
00:35:35,714 --> 00:35:39,049
And when I fill this whole thing up
with black powder and ignite it,

836
00:35:39,050 --> 00:35:42,618
The flame will move through
the grooves into the nozzles

837
00:35:42,619 --> 00:35:47,255
And ignite all the rockets
at the same exact time.

838
00:35:47,256 --> 00:35:51,091
And there's no time
to test Tory's groove

839
00:35:51,092 --> 00:35:52,359
Like the present.

840
00:35:52,360 --> 00:35:54,961
In 3, 2, 1.

841
00:35:58,466 --> 00:35:59,999
Yeah!

842
00:36:00,000 --> 00:36:03,702
Oh! That looked
so synchronized.

843
00:36:03,703 --> 00:36:06,005
Whoo-hoo!

844
00:36:06,006 --> 00:36:07,539
Wow.

845
00:36:07,540 --> 00:36:09,040
That was synchronized.

846
00:36:09,041 --> 00:36:11,341
That is
a beautiful ignition system.

847
00:36:11,342 --> 00:36:13,476
I see good things
in our future.

848
00:36:13,477 --> 00:36:14,878
Back inside,

849
00:36:14,879 --> 00:36:17,746
The wings, the fins,
and the skateboard rail

850
00:36:17,747 --> 00:36:20,413
Are the key additions
to our makeshift vehicle

851
00:36:20,414 --> 00:36:25,050
That just might launch
a stand-in man 150 feet.

852
00:36:25,051 --> 00:36:27,119
And it's probably just as well

853
00:36:27,120 --> 00:36:28,787
He's missing the back
of his head.

854
00:36:28,788 --> 00:36:30,889
If all of our calculations
are correct,

855
00:36:30,890 --> 00:36:33,191
We should see this fireworks man

856
00:36:33,192 --> 00:36:35,226
Fly up that ramp
and across the lake.

857
00:36:35,227 --> 00:36:38,495
Or it's gonna fail miserably
and explode on the ramp.

858
00:36:44,879 --> 00:36:47,733
With the myth of the "CSI" stun gun wrapped up,

859
00:36:47,870 --> 00:36:49,503
The boys feel the need
to go out

860
00:36:49,504 --> 00:36:53,039
In a totally gratuitous
blaze of glory.

861
00:36:53,040 --> 00:36:57,209
Jamie left me this really
cryptic message which said only,

862
00:36:57,210 --> 00:37:00,746
Bring him a burnable perp
and dress for a fire.

863
00:37:02,282 --> 00:37:05,717
I am, as they say, intrigued.

864
00:37:05,718 --> 00:37:07,219
Here we go.

865
00:37:07,220 --> 00:37:10,222
Adam dresses his man
in a fitting fashion.

866
00:37:10,223 --> 00:37:14,058
And the shirt, as you've
guessed, is the famous flannel.

867
00:37:14,059 --> 00:37:16,928
Ah. Are you ready,
little buddy?

868
00:37:19,197 --> 00:37:21,363
This is actually
the standard model of robot

869
00:37:21,364 --> 00:37:23,763
That are all of Grant's servants
back at his castle.

870
00:37:36,441 --> 00:37:39,943
So, the savage
awaits the barbarian.

871
00:37:39,944 --> 00:37:42,211
And Jamie's weapon of choice

872
00:37:42,212 --> 00:37:46,348
Is a vintage vietnam-era
gasoline flamethrower.

873
00:37:46,349 --> 00:37:48,283
Ah, hey.
What do you got?

874
00:37:48,284 --> 00:37:50,051
Stand clear.
I'm going hot.

875
00:37:50,052 --> 00:37:51,519
Okay.

876
00:37:56,490 --> 00:37:58,991
Long-time viewers know
that sometimes,

877
00:37:58,992 --> 00:38:02,261
When a myth falls frustratingly
short of confirmation...

878
00:38:02,262 --> 00:38:03,795
You see any bullet holes?

879
00:38:03,796 --> 00:38:05,397
I don't see any at all.
No.

880
00:38:05,398 --> 00:38:06,564
...We like to, uh...

881
00:38:06,565 --> 00:38:08,099
Firing.

882
00:38:08,100 --> 00:38:09,867
...Turn it up a notch or 10.

883
00:38:13,271 --> 00:38:15,738
Once again, Jamie's ready
to skip the method

884
00:38:15,739 --> 00:38:17,373
And go straight for the mayhem.

885
00:38:18,808 --> 00:38:22,210
3, 2, 1.

886
00:38:27,349 --> 00:38:30,584
There's no better way
to unleash hell

887
00:38:30,585 --> 00:38:31,785
Than a 60-foot flame.

888
00:38:37,990 --> 00:38:39,824
Nice!

889
00:38:48,799 --> 00:38:51,367
That's what I'm talking about.

890
00:38:54,804 --> 00:38:56,738
Very post-apocalyptic
of you.

891
00:38:56,739 --> 00:38:58,439
Is that hot enough for you?

892
00:38:58,440 --> 00:39:02,043
Well, that was only ever going
to end one way.

893
00:39:02,044 --> 00:39:03,810
And thanks to a $5 shirt,

894
00:39:03,811 --> 00:39:05,612
We've got
a million-dollar memory.

895
00:39:16,723 --> 00:39:19,490
Any kid who's ever read
a comic book

896
00:39:19,491 --> 00:39:22,192
Has surely dreamed
of personal rocket propulsion.

897
00:39:22,193 --> 00:39:23,661
According to fans,

898
00:39:23,662 --> 00:39:27,897
One man actually flew 150 feet
with skyrockets,

899
00:39:27,898 --> 00:39:30,133
So we had to see for ourselves.

900
00:39:30,134 --> 00:39:34,003
We've studied the physics, built
the best amateur rig we could,

901
00:39:34,004 --> 00:39:36,638
And found a flooded quarry
for the crash landing.

902
00:39:36,639 --> 00:39:39,007
Oh, this place is cool.

903
00:39:39,008 --> 00:39:40,841
Whoa!

904
00:39:40,842 --> 00:39:43,911
Already dangerous.

905
00:39:43,912 --> 00:39:46,246
So, if our math is correct

906
00:39:46,247 --> 00:39:47,914
And our fireworks
do what they're supposed to,

907
00:39:47,915 --> 00:39:51,049
We should get a man landing
in the lake any time now.

908
00:39:51,050 --> 00:39:53,284
Ooh. Nice.

909
00:39:53,285 --> 00:39:55,419
He's got to not explode
on the launch pad,

910
00:39:55,420 --> 00:39:57,119
Have a stable flight,

911
00:39:57,120 --> 00:40:01,322
And, according to the myth,
fly at least 150 feet.

912
00:40:01,323 --> 00:40:03,056
I hope he does it.

913
00:40:03,057 --> 00:40:06,425
Now to check
on correct starting weight.

914
00:40:06,426 --> 00:40:08,259
All right.
How much does he weigh?

915
00:40:08,260 --> 00:40:09,827
Okay.

916
00:40:09,828 --> 00:40:11,795
183.

917
00:40:11,796 --> 00:40:13,999
Well, the sled weighs 60,
so that makes him 243.

918
00:40:14,000 --> 00:40:17,336
That's perfect. That's exactly
around what we need.

919
00:40:17,337 --> 00:40:18,371
All right.

920
00:40:18,372 --> 00:40:20,907
Load him up.
Let's do this.

921
00:40:20,908 --> 00:40:24,410
Kari and Grant
fit skateboards to rails

922
00:40:24,411 --> 00:40:27,646
For a hopefully
friction-free ride,

923
00:40:27,647 --> 00:40:29,414
While Tory sets the charge

924
00:40:29,415 --> 00:40:32,517
To ignite every last one
of those 400 rockets.

925
00:40:32,518 --> 00:40:36,153
Fingers crossed,
they will launch together.

926
00:40:36,154 --> 00:40:38,955
Now, I know this might not seem
like a lot of black powder,

927
00:40:38,956 --> 00:40:40,490
But I'm actually using 6 ounces.

928
00:40:40,491 --> 00:40:43,092
I mean, that would be plenty
to fire off a cannonball.

929
00:40:43,093 --> 00:40:45,360
So the fuses are fixed,

930
00:40:45,361 --> 00:40:47,062
And the very last bits
of the puzzle

931
00:40:47,063 --> 00:40:49,799
Slide neatly enough into place.

932
00:40:49,800 --> 00:40:51,633
You're like a surgeon
with that thing.

933
00:40:53,035 --> 00:40:55,436
Do you guys realize
this is a dream come true?

934
00:40:55,437 --> 00:40:56,670
I think for all of us.

935
00:40:56,671 --> 00:40:58,004
It's a thing of beauty.

936
00:40:58,005 --> 00:41:00,405
But let's remember
that fireworks man

937
00:41:00,406 --> 00:41:02,740
Still has a hell of a lot
to live up to.

938
00:41:02,741 --> 00:41:06,076
For this myth to be possible,
we need two things to happen.

939
00:41:06,077 --> 00:41:10,046
One, we need Buster to launch
off that ramp and hit the water.

940
00:41:10,047 --> 00:41:12,448
And two, we need him to not be

941
00:41:12,449 --> 00:41:15,352
A burning mass
of melting Buster.

942
00:41:15,353 --> 00:41:17,154
You can bet your bionic britches

943
00:41:17,155 --> 00:41:19,858
That Buster's in full agreement.

944
00:41:19,859 --> 00:41:22,862
We're all wired up,
ready to go.

945
00:41:22,863 --> 00:41:27,899
This is fireworks man
in 3, 2, 1.

946
00:41:39,610 --> 00:41:42,845
We got a launch.
It's still going. Look.

947
00:41:44,248 --> 00:41:46,348
From the shore,

948
00:41:46,349 --> 00:41:49,184
It's a dazzling display
of smoke and sparkles,

949
00:41:49,185 --> 00:41:51,919
But just put yourself
in Buster's shoes.

950
00:41:57,559 --> 00:42:00,327
It was looking so good.

951
00:42:00,328 --> 00:42:01,762
We got a perfect launch.

952
00:42:01,763 --> 00:42:04,630
He was going up the ramp,
he gets to the top of the ramp,

953
00:42:04,631 --> 00:42:07,733
And that's where everything
goes all wrong.

954
00:42:07,734 --> 00:42:11,370
In fact,
it's the good, the bad,

955
00:42:11,371 --> 00:42:13,505
The ugly, and the awesome

956
00:42:13,506 --> 00:42:16,874
All in one amazing launch.

957
00:42:16,875 --> 00:42:19,076
As Buster gets dragged
from the drink...

958
00:42:19,077 --> 00:42:21,111
Hi.

959
00:42:21,112 --> 00:42:24,013
...It's time to reflect
on what worked and what didn't.

960
00:42:24,014 --> 00:42:26,382
So, we got
simultaneous ignition,

961
00:42:26,383 --> 00:42:27,883
We used actual fireworks,

962
00:42:27,884 --> 00:42:30,451
He made it off the ramp
and into the water.

963
00:42:30,452 --> 00:42:33,487
Yeah, and on top of that, he
didn't catch on fire or explode,

964
00:42:33,488 --> 00:42:35,857
Which means he would have
survived the launch.

965
00:42:35,858 --> 00:42:37,525
Well, he might have
survived the launch,

966
00:42:37,526 --> 00:42:39,160
But I'm not so sure
about the landing.

967
00:42:39,161 --> 00:42:41,228
And we didn't fulfill all
the criteria of the myth.

968
00:42:41,229 --> 00:42:43,330
I mean, he did not go
the 150 feet we talked about.

969
00:42:43,331 --> 00:42:45,465
It's one
of the toughest decisions

970
00:42:45,466 --> 00:42:47,233
They've ever been faced with.

971
00:42:47,234 --> 00:42:49,135
On the one hand,

972
00:42:49,136 --> 00:42:52,204
It was really only those loose
legs tipping the sled backwards

973
00:42:52,205 --> 00:42:53,772
That spoiled the party.

974
00:42:53,773 --> 00:42:57,012
On the other hand,
Buster only flew 30 feet,

975
00:42:57,188 --> 00:42:59,889
And there's no doubt
that the yahoo in the myth

976
00:42:59,890 --> 00:43:03,625
Went to way less trouble than
we did with far fewer resources.

977
00:43:03,626 --> 00:43:07,763
So, with regret, that's where
we're drawing the line.

978
00:43:07,764 --> 00:43:10,030
So, I think we're still gonna
have to call this one busted.

979
00:43:10,031 --> 00:43:11,531
All right. Busted.

980
00:43:11,532 --> 00:43:13,132
Busted.

981
00:43:13,133 --> 00:43:14,867
But, man, what a way
to bust a myth.

982
00:43:14,868 --> 00:43:15,901
Right.

983
00:43:23,475 --> 00:43:24,224
