1
00:00:00,000 --> 00:00:04,000
Attention, viewers, do not try anything you're about to see at home.

2
00:00:04,000 --> 00:00:06,000
We're what you call experts.

3
00:00:10,000 --> 00:00:14,000
On this blockbusting epic episode of Mythbusters...

4
00:00:16,000 --> 00:00:17,000
James Cameron...

5
00:00:17,000 --> 00:00:18,000
Yeah, baby.

6
00:00:18,000 --> 00:00:20,000
This is James Frickin' Cameron.

7
00:00:20,000 --> 00:00:22,000
...has a conundrum.

8
00:00:22,000 --> 00:00:24,000
I am indeed James Frickin' Cameron.

9
00:00:24,000 --> 00:00:29,000
Thousands of furious fans flooding the Internet claim Cameron got it wrong.

10
00:00:29,000 --> 00:00:31,000
It's alive!

11
00:00:31,000 --> 00:00:32,000
That rose...

12
00:00:32,000 --> 00:00:33,000
Don't call me Rose.

13
00:00:33,000 --> 00:00:34,000
...and Jack...

14
00:00:34,000 --> 00:00:38,000
Hope, Hope, Hope could have both lived to tell their Titanic tale

15
00:00:38,000 --> 00:00:41,000
by sharing their floating fluxes.

16
00:00:41,000 --> 00:00:43,000
Stay on it! Stay on Rose!

17
00:00:44,000 --> 00:00:49,000
Meanwhile, surfs up, up and away for Carrie Grant, Tori...

18
00:00:49,000 --> 00:00:50,000
You could possibly go wrong.

19
00:00:50,000 --> 00:00:51,000
...and Buster.

20
00:00:51,000 --> 00:00:55,000
Our trio of intrepid rocket scientists ask...

21
00:00:55,000 --> 00:00:57,000
Yeah, that was a crazy one.

22
00:00:57,000 --> 00:01:01,000
Can you really catch a wild, rad ride with rockets?

23
00:01:03,000 --> 00:01:04,000
You're dead!

24
00:01:07,000 --> 00:01:09,000
Who are the Mythbusters?

25
00:01:10,000 --> 00:01:11,000
Adam Savage...

26
00:01:11,000 --> 00:01:13,000
I reject your reality and substitute my own.

27
00:01:13,000 --> 00:01:14,000
...and Jamie Heinemann.

28
00:01:15,000 --> 00:01:16,000
We're gonna have an adventure.

29
00:01:16,000 --> 00:01:21,000
...between them more than 30 years of special effects experience...

30
00:01:21,000 --> 00:01:23,000
...together with Tori Valenci...

31
00:01:23,000 --> 00:01:24,000
Time to go, Diane.

32
00:01:24,000 --> 00:01:25,000
...Grant Imajaro...

33
00:01:25,000 --> 00:01:26,000
Start the car!

34
00:01:27,000 --> 00:01:28,000
...and Carrie Byron.

35
00:01:28,000 --> 00:01:29,000
Fire!

36
00:01:30,000 --> 00:01:32,000
They don't just tell the Myths...

37
00:01:33,000 --> 00:01:35,000
They put them to the test.

38
00:01:42,000 --> 00:01:45,000
First up, Adam and Jamie tackle an internet sensation...

39
00:01:45,000 --> 00:01:49,000
...that's causing an A-list viewer extreme vexation.

40
00:01:50,000 --> 00:01:51,000
Hey.

41
00:01:51,000 --> 00:01:56,000
Hey, we have a very exciting Myth today from an unbelievably special viewer.

42
00:01:56,000 --> 00:01:57,000
Who's that?

43
00:01:57,000 --> 00:01:59,000
None other than James Cameron.

44
00:01:59,000 --> 00:02:02,000
You mean that guy that went to the bottom of the Marianas Trench?

45
00:02:02,000 --> 00:02:03,000
That's the guy.

46
00:02:03,000 --> 00:02:06,000
I was thinking of him more as a movie director, but yes, that's the guy.

47
00:02:06,000 --> 00:02:11,000
So, James Cameron also directs movies, is what you're telling me?

48
00:02:11,000 --> 00:02:12,000
Yes, he does.

49
00:02:12,000 --> 00:02:13,000
Really?

50
00:02:13,000 --> 00:02:14,000
So what's his myth?

51
00:02:14,000 --> 00:02:16,000
Actually, I think we should talk to him.

52
00:02:16,000 --> 00:02:17,000
Okay.

53
00:02:21,000 --> 00:02:22,000
Hey, James.

54
00:02:22,000 --> 00:02:25,000
Hey, could you tell Jamie what you told me?

55
00:02:25,000 --> 00:02:26,000
Sure.

56
00:02:26,000 --> 00:02:29,000
So for the last few months since I released Titanic in 3D,

57
00:02:29,000 --> 00:02:35,000
I've been getting dozens of emails every day saying that Rose is a selfish so-and-so,

58
00:02:35,000 --> 00:02:37,000
and Jack's an idiot.

59
00:02:37,000 --> 00:02:39,000
Who are Rose and Jack?

60
00:02:40,000 --> 00:02:42,000
Two main characters of the movie.

61
00:02:42,000 --> 00:02:47,000
All right, Jamie, at the end of the film, Titanic, Rose and Jack are distributed among the detritus of the sunken ship,

62
00:02:47,000 --> 00:02:51,000
and Rose is perched on a piece of wood, and Jack is not.

63
00:02:52,000 --> 00:02:54,000
Because there wasn't enough buoyancy to support both of them?

64
00:02:54,000 --> 00:02:59,000
Right, and Jack makes the ultimate sacrifice, and he dies so that Rose can live.

65
00:02:59,000 --> 00:03:02,000
Right, so anyway, these thousands of fans think that I got it wrong,

66
00:03:02,000 --> 00:03:05,000
and that they both could have been supported by the board, and they both could have lived,

67
00:03:05,000 --> 00:03:08,000
so this is what I want you guys to test.

68
00:03:08,000 --> 00:03:11,000
Wait, so you made a movie about the Titanic?

69
00:03:11,000 --> 00:03:12,000
Yes.

70
00:03:13,000 --> 00:03:14,000
Why would you do that?

71
00:03:14,000 --> 00:03:16,000
We already know how it ends.

72
00:03:16,000 --> 00:03:18,000
He doesn't get out much, does he?

73
00:03:18,000 --> 00:03:19,000
No, he doesn't.

74
00:03:20,000 --> 00:03:26,000
The movie, the second highest grossing of all time, was anything but a disaster,

75
00:03:26,000 --> 00:03:29,000
but the ending has caused a storm of protest.

76
00:03:30,000 --> 00:03:33,000
Dispens to survive in the freezing cold North Atlantic.

77
00:03:33,000 --> 00:03:35,000
Stay on it. Stay on, Rose.

78
00:03:35,000 --> 00:03:39,000
Jack and Rose attempt to clamber onto a piece of debris,

79
00:03:39,000 --> 00:03:42,000
and seemingly there's room aboard for just one,

80
00:03:42,000 --> 00:03:48,000
and Jack, being the noble hero he is, sacrifices himself to keep Rose's head above water.

81
00:03:49,000 --> 00:03:53,000
But multitudes of Titanic and MythBuster fans don't believe it.

82
00:03:53,000 --> 00:03:58,000
James Cameron's inbox has been flooded with the theory that both hero and heroine

83
00:03:58,000 --> 00:04:01,000
could have lived to tell their Titanic tale.

84
00:04:01,000 --> 00:04:04,000
Okay, so I need you guys to find out who's right.

85
00:04:04,000 --> 00:04:07,000
These so-called fans are my movie.

86
00:04:07,000 --> 00:04:10,000
Okay, it seems to me the place we start is with buoyancy.

87
00:04:10,000 --> 00:04:14,000
The question is, could the board possibly have supported both Rose and Jack?

88
00:04:14,000 --> 00:04:17,000
I agree, but the second issue is about survivors.

89
00:04:17,000 --> 00:04:20,000
The second issue is about survival in those freezing conditions.

90
00:04:20,000 --> 00:04:23,000
You mean, if they both could have died regardless of the board?

91
00:04:23,000 --> 00:04:24,000
Exactly.

92
00:04:24,000 --> 00:04:28,000
What's the agate started doing, some small-scale testing with the mini-board and the mini-Rose and Jack?

93
00:04:28,000 --> 00:04:31,000
Why don't I start to prep for some hypothermia tests?

94
00:04:31,000 --> 00:04:33,000
And I'll get back to sweeping up.

95
00:04:33,000 --> 00:04:34,000
Awesome.

96
00:04:34,000 --> 00:04:38,000
So the epic full-scale Jack and Rose reenactment comes later.

97
00:04:38,000 --> 00:04:41,000
Let's see, here we can both get on this thing.

98
00:04:41,000 --> 00:04:46,000
Because this Titanic tale won't set sail until it's been tested in safer waters.

99
00:04:46,000 --> 00:04:49,000
Where the guys opt for an efficient division of labor.

100
00:04:49,000 --> 00:04:54,000
Jamie's taking charge of how to quantify and replicate the hero's hypothermia.

101
00:04:54,000 --> 00:04:58,000
And grumble about the lack of logic in love.

102
00:04:58,000 --> 00:05:01,000
While Adam's cutting things down to size.

103
00:05:01,000 --> 00:05:04,000
Okay, the myth in miniature. So what are you gonna do?

104
00:05:04,000 --> 00:05:07,000
I'm glad you asked. I'm gonna start by playing with dolls.

105
00:05:07,000 --> 00:05:09,000
I'm gonna make some very accurate dolls of Rose and Jack,

106
00:05:09,000 --> 00:05:13,000
accurate both in terms of their size, but also in their weight.

107
00:05:14,000 --> 00:05:18,000
And then I'm gonna put them on a piece of wood that is exactly the same type of wood as the original.

108
00:05:18,000 --> 00:05:19,000
Right, so white oak.

109
00:05:19,000 --> 00:05:23,000
Yes, and basically put that in a tub full of salty water and see what happens.

110
00:05:23,000 --> 00:05:25,000
And prove my movie was right.

111
00:05:25,000 --> 00:05:26,000
Maybe.

112
00:05:26,000 --> 00:05:27,000
Yeah, maybe.

113
00:05:27,000 --> 00:05:31,000
With Adam's quarter-sized dolls cut and sewn, they're ready to put on some weight.

114
00:05:31,000 --> 00:05:34,000
Exactly how much is kind of clever.

115
00:05:34,000 --> 00:05:38,000
Now, given that this guy is one quarter my size, does that make him one quarter my weight?

116
00:05:38,000 --> 00:05:39,000
No!

117
00:05:39,000 --> 00:05:42,000
Let me explain, because most people get this wrong.

118
00:05:42,000 --> 00:05:45,000
This is a two-inch cube of aluminum.

119
00:05:45,000 --> 00:05:49,000
This is exactly one quarter scale, a half-inch cube of aluminum.

120
00:05:49,000 --> 00:05:52,000
This one weighs 352 grams.

121
00:05:52,000 --> 00:05:55,000
This one weighs 5.5 grams.

122
00:05:55,000 --> 00:05:57,000
Actually, just a shade under.

123
00:05:57,000 --> 00:05:58,000
How do we get there from there?

124
00:05:58,000 --> 00:06:01,000
Well, what you do is you scale by what's called the cube root.

125
00:06:01,000 --> 00:06:05,000
That means three separate times, because there are three separate dimensions, length, width, and height.

126
00:06:05,000 --> 00:06:08,000
You take 352 and divide it by four.

127
00:06:08,000 --> 00:06:13,000
You're again divided by four one more time and you get 5.5 grams.

128
00:06:13,000 --> 00:06:14,000
Isn't that cool?

129
00:06:14,000 --> 00:06:20,000
Add to achieve the correctly scaled weight, Adam fills the dolls with beans and knowledge.

130
00:06:20,000 --> 00:06:21,000
Ready, Jack?

131
00:06:21,000 --> 00:06:23,000
I'm going to fill your head full of knowledge.

132
00:06:23,000 --> 00:06:24,000
Learn that stuff.

133
00:06:24,000 --> 00:06:26,000
Yeah, it's good for you.

134
00:06:26,000 --> 00:06:27,000
Science.

135
00:06:27,000 --> 00:06:28,000
Math.

136
00:06:28,000 --> 00:06:33,000
Next up, Adam brings the same scaling rigor to the key prop piece.

137
00:06:33,000 --> 00:06:38,000
Using the same type of wood, he accurately scales each dimension by a quarter.

138
00:06:38,000 --> 00:06:43,000
And with a final coat of theatrical magic, perfect.

139
00:06:43,000 --> 00:06:48,000
Adam is just a bathtub full of salty seawater, sure of being ready.

140
00:06:48,000 --> 00:06:49,000
Excellent.

141
00:06:49,000 --> 00:06:52,000
We are at a proper level of ocean salinity.

142
00:06:52,000 --> 00:06:55,000
All right, we're getting ready for a quarter scale test.

143
00:06:55,000 --> 00:07:00,000
I've got my piece of wood that Rose floated on and I've got a scale weighted Rose.

144
00:07:00,000 --> 00:07:04,000
We should see identical behavior to the full-size one.

145
00:07:04,000 --> 00:07:05,000
Here we go.

146
00:07:05,000 --> 00:07:07,000
Rose lies down on it.

147
00:07:07,000 --> 00:07:11,000
Oh, oh, that actually, wow.

148
00:07:11,000 --> 00:07:16,000
In the movie, you can see that it's lapping on most of the board and that's exactly what we're getting here.

149
00:07:16,000 --> 00:07:17,000
So far, so good.

150
00:07:17,000 --> 00:07:22,000
Adam's eye for detailed and mathematically accurate scaling has paid off.

151
00:07:22,000 --> 00:07:25,000
Now, what about the myth itself?

152
00:07:25,000 --> 00:07:27,000
Could Jack have jumped aboard?

153
00:07:27,000 --> 00:07:28,000
Here we go.

154
00:07:28,000 --> 00:07:30,000
Jack and Rose.

155
00:07:30,000 --> 00:07:31,000
Nope.

156
00:07:31,000 --> 00:07:32,000
Whoa, whoa, whoa.

157
00:07:32,000 --> 00:07:33,000
They're about sinking.

158
00:07:33,000 --> 00:07:34,000
Hold on.

159
00:07:34,000 --> 00:07:38,000
It doesn't look like they can stay afloat.

160
00:07:38,000 --> 00:07:44,000
That means this maiden voyage myth is on thin ice and the movie's looking like the real deal.

161
00:07:44,000 --> 00:07:46,000
Science is on my side.

162
00:07:46,000 --> 00:07:51,000
So what we see in the movie where he tries to climb on and the thing starts to zip over,

163
00:07:51,000 --> 00:07:53,000
seems like it's totally accurate.

164
00:07:53,000 --> 00:07:54,000
There they go.

165
00:07:54,000 --> 00:07:59,000
Well, it seems that all the time I spent making my dolls exactly one quarter scale to their counterparts

166
00:07:59,000 --> 00:08:02,000
and using the exact same wood for the wood piece has paid off.

167
00:08:02,000 --> 00:08:04,000
We've learned some important things in scale.

168
00:08:04,000 --> 00:08:11,000
First and foremost, it would seem that all the behavior we see out of this piece of wood in the movie is accurate to reality.

169
00:08:11,000 --> 00:08:15,000
It is just barely buoyant enough to hold Rose's body out of the water.

170
00:08:15,000 --> 00:08:20,000
It also appears that it is not buoyant enough to keep Rose and Jack's body out of the water.

171
00:08:20,000 --> 00:08:24,000
Now, of course, Jamie and I are going to experiment with this in full scale.

172
00:08:24,000 --> 00:08:26,000
Yep, it's too early to call it yet.

173
00:08:26,000 --> 00:08:28,000
There they go.

174
00:08:28,000 --> 00:08:29,000
No.

175
00:08:29,000 --> 00:08:33,000
Because the problem is not just about buoyancy.

176
00:08:33,000 --> 00:08:41,000
To find out if the film failed in the survivability stakes, Adam and Jamie will examine every aspect of cold water endurance.

177
00:08:41,000 --> 00:08:43,000
It's alive.

178
00:08:43,000 --> 00:08:46,000
Enter thermal man.

179
00:08:46,000 --> 00:08:47,000
There it goes.

180
00:08:47,000 --> 00:08:48,000
Whoa.

181
00:08:48,000 --> 00:08:52,000
Adam and Jamie, Cyborg Midwives.

182
00:08:52,000 --> 00:09:01,000
Up next, Carrie, Grant and Tori are counting down to a wet and wild lift off.

183
00:09:01,000 --> 00:09:05,000
All right, I have a myth for you guys that I have been wanting to try since I started surfing.

184
00:09:05,000 --> 00:09:06,000
What?

185
00:09:06,000 --> 00:09:10,000
A California surfer moves to the Midwest and gets a little frustrated.

186
00:09:10,000 --> 00:09:12,000
Oh, let me guess.

187
00:09:12,000 --> 00:09:13,000
No waves, dude.

188
00:09:13,000 --> 00:09:14,000
Exactly.

189
00:09:14,000 --> 00:09:19,000
But instead of getting bummed out, he decides to make a rocket powered surfboard.

190
00:09:19,000 --> 00:09:20,000
Are you kidding me?

191
00:09:20,000 --> 00:09:21,000
Are you making this up?

192
00:09:21,000 --> 00:09:22,000
No.

193
00:09:22,000 --> 00:09:23,000
Is that perfect?

194
00:09:23,000 --> 00:09:27,000
He takes a giant rocket, straps it to a surfboard, heads out onto a flat lake.

195
00:09:27,000 --> 00:09:28,000
It starts surfing.

196
00:09:28,000 --> 00:09:29,000
Okay.

197
00:09:29,000 --> 00:09:30,000
No waves, no problem.

198
00:09:30,000 --> 00:09:31,000
I like it.

199
00:09:31,000 --> 00:09:39,000
The story goes that a souped up surfboard gave its rider a 20 miles per hour ride for 30 nail biting seconds.

200
00:09:39,000 --> 00:09:45,000
But could a single super-sized rocket really turn a languid lake into a radical ride?

201
00:09:45,000 --> 00:09:48,000
Or will this myth be a Duncan disaster?

202
00:09:48,000 --> 00:09:50,000
All right, what do you guys think?

203
00:09:50,000 --> 00:09:52,000
Okay, well, I have my doubts.

204
00:09:52,000 --> 00:09:56,000
Large rockets tend to have a lot of thrust in over a really small period of time.

205
00:09:56,000 --> 00:09:58,000
Fair enough, but you know, we have to start somewhere.

206
00:09:58,000 --> 00:10:02,000
Let's just start with Buster on a surfboard with one really big rocket.

207
00:10:02,000 --> 00:10:04,000
All right, well, I know just the place.

208
00:10:04,000 --> 00:10:08,000
Look how gorgeous this is.

209
00:10:08,000 --> 00:10:10,000
Man, it's totally flat.

210
00:10:10,000 --> 00:10:11,000
There's no waves.

211
00:10:11,000 --> 00:10:13,000
But that's no problem for us.

212
00:10:13,000 --> 00:10:15,000
No problem at all.

213
00:10:15,000 --> 00:10:20,000
We're here at the Quarry Lakes at the East Bay Regional Parks District so that we can test the rocket surfer myth.

214
00:10:20,000 --> 00:10:28,000
Now, this myth is where a guy straps one big rocket to his surfboard and sails across the lake going 20 miles an hour for a 30-second ride.

215
00:10:28,000 --> 00:10:29,000
Why?

216
00:10:29,000 --> 00:10:30,000
Because lakes are flat.

217
00:10:30,000 --> 00:10:31,000
They don't have waves.

218
00:10:31,000 --> 00:10:37,000
No matter what, this is going to be an awesome day.

219
00:10:37,000 --> 00:10:39,000
You guys ready to rocket?

220
00:10:39,000 --> 00:10:41,000
Yeah, myth Buster style.

221
00:10:41,000 --> 00:10:46,000
This is our rocket surfboard, just like the myth, one big rocket.

222
00:10:46,000 --> 00:10:47,000
It's surfs up, dude.

223
00:10:47,000 --> 00:10:51,000
Now, because we don't know exactly what's going to happen, we're going to use Buster.

224
00:10:51,000 --> 00:10:54,000
And because Buster can't stand, I've built this back to the shop.

225
00:10:54,000 --> 00:10:57,000
We're going to attach it to this and see how it goes.

226
00:10:57,000 --> 00:10:59,000
Nice pose, dude.

227
00:10:59,000 --> 00:11:01,000
This is our rocket motor stand.

228
00:11:01,000 --> 00:11:03,000
This is what goes inside of it.

229
00:11:03,000 --> 00:11:04,000
It's a Cesaroni K-Motor.

230
00:11:04,000 --> 00:11:12,000
You may remember from our James Bond ejector seat episode, four of these is enough to launch a guy straight up in the air about 25 feet.

231
00:11:12,000 --> 00:11:13,000
Fire!

232
00:11:18,000 --> 00:11:23,000
And because we're not fighting gravity on this, one of these should be more than enough to surf a lake.

233
00:11:23,000 --> 00:11:28,000
The actual details of the rocket and the myth are few and far between.

234
00:11:28,000 --> 00:11:29,000
Ouchy.

235
00:11:29,000 --> 00:11:30,000
That's right. It's built for comfort.

236
00:11:30,000 --> 00:11:38,000
But the advantage of their K-Motor is that it's both powerful and relatively available, making it a realistic rocket of choice.

237
00:11:38,000 --> 00:11:42,000
Is it just me or are we actually strapping rockets to a surfboard?

238
00:11:42,000 --> 00:11:48,000
With Buster ready to ride, all that's left for this surfing saga is a helping hand.

239
00:11:48,000 --> 00:11:56,000
So we've learned through all of our various rocket experiments through the years, it's really important to keep your rocket stable using a rail system.

240
00:11:56,000 --> 00:12:03,000
It's exactly what this is. This is a 20 foot long guide rail. Hopefully keep the surfboard upright, at least for the first 20 feet.

241
00:12:03,000 --> 00:12:08,000
Yep, the team has proven a stable launch is a prerequisite for a successful flight.

242
00:12:08,000 --> 00:12:09,000
Oh, how's he looking?

243
00:12:09,000 --> 00:12:11,000
All right, we're good.

244
00:12:11,000 --> 00:12:15,000
I hope this goes well, because if it does, I think I might want to go for a ride.

245
00:12:15,000 --> 00:12:21,000
Contrary to the don't try this at home mantra, Tori's keen to take a turn to test this for himself.

246
00:12:21,000 --> 00:12:22,000
All right, we're wired.

247
00:12:22,000 --> 00:12:26,000
But first, let's see how badly Buster gets busted up.

248
00:12:29,000 --> 00:12:38,000
This is rocket surfer with one big rock. Here we go. In three, two, one.

249
00:12:42,000 --> 00:12:45,000
That looked a little dangerous.

250
00:12:45,000 --> 00:12:47,000
That is a lot of thrust.

251
00:12:49,000 --> 00:12:51,000
That was a crazy flip.

252
00:12:51,000 --> 00:12:57,000
Crazy flip is right. The moment Buster left the guide rail, he went heels overhead, literally.

253
00:12:57,000 --> 00:13:01,000
So our rocket surfer got a perfect 10 for gymnastics. We got a nice loop doodle.

254
00:13:01,000 --> 00:13:07,000
What I think happened is that we had all of our weight in the back of the surfboard, as well as a huge amount of power.

255
00:13:07,000 --> 00:13:12,000
And it pulled all at once, pushing our surfboard to curve upward and flip over.

256
00:13:12,000 --> 00:13:14,000
Don't die on me.

257
00:13:15,000 --> 00:13:16,000
You gonna be all right?

258
00:13:16,000 --> 00:13:17,000
Nah, he's dead.

259
00:13:17,000 --> 00:13:18,000
He's dead.

260
00:13:19,000 --> 00:13:24,000
Buster may be dead in the water, but the myth is hanging on.

261
00:13:24,000 --> 00:13:28,000
The team has a few ideas that might just bring it back to life.

262
00:13:29,000 --> 00:13:33,000
Coming up when a Hollywood big hitter asked for myth-busting help.

263
00:13:33,000 --> 00:13:37,000
It's like I just picked up all of my blood veins and light them on the table.

264
00:13:37,000 --> 00:13:41,000
Dr. Frankenheinemann makes a human metabolism.

265
00:13:41,000 --> 00:13:43,000
It's beating just like a heart.

266
00:13:49,000 --> 00:14:00,000
In 1912, the Titanic hit her iceberg nemesis and has lain in the eerie deep of the North Atlantic ever since.

267
00:14:00,000 --> 00:14:08,000
But in 2012, the ship has hit the fan for the movie. The fans are in a furious fever over the ending.

268
00:14:08,000 --> 00:14:13,000
So far, in small scale at least, it looks like Mr. Cameron nailed it.

269
00:14:13,000 --> 00:14:16,000
It doesn't look like they can stay afloat.

270
00:14:17,000 --> 00:14:18,000
Science is on my side.

271
00:14:18,000 --> 00:14:20,000
But the guys aren't stopping there.

272
00:14:20,000 --> 00:14:28,000
To test the mortal limits of hypothermia, they're creating a stand-in with a circulatory system made from superconductive copper,

273
00:14:28,000 --> 00:14:32,000
embedded in gel, close to the density of human flesh.

274
00:14:32,000 --> 00:14:35,000
It's complex and very, very cool.

275
00:14:35,000 --> 00:14:37,000
I think that ought to work just fine.

276
00:14:37,000 --> 00:14:41,000
Look, this whole thing boils down to whether the way their survival was portrayed was accurate.

277
00:14:41,000 --> 00:14:47,000
In addition to the main question, was the board big enough, we also need to know whether board or no board,

278
00:14:47,000 --> 00:14:52,000
anyone could have survived temperatures identical to those the day the Titanic sank.

279
00:14:52,000 --> 00:14:57,000
We need to know whether Jack and Rose would have survived long enough to be rescued.

280
00:14:57,000 --> 00:15:02,000
To find out, we're going to have to do some high-tech hypothermic testing to answer that question.

281
00:15:02,000 --> 00:15:07,000
And the crucial reference for those tests is how long did it take for rescue?

282
00:15:12,000 --> 00:15:17,000
Alright, James, so for our hypothermia testing, we need to know exactly how long it took Rose to be rescued,

283
00:15:17,000 --> 00:15:20,000
but in the film, it's a little ambiguous.

284
00:15:20,000 --> 00:15:21,000
What's the answer?

285
00:15:21,000 --> 00:15:26,000
We show her getting rescued by 5th Officer Low, and he, according to survivor testimony,

286
00:15:26,000 --> 00:15:29,000
started his search about 20 minutes after the ship sank.

287
00:15:29,000 --> 00:15:30,000
And how long did he search for?

288
00:15:30,000 --> 00:15:32,000
About 45 minutes.

289
00:15:32,000 --> 00:15:37,000
Okay, so he could have found her anywhere between 20 and 65 minutes after she hits the water.

290
00:15:37,000 --> 00:15:41,000
Alright, but let's push it toward the back end, because we show her in the movie being one of the last ones rescued.

291
00:15:41,000 --> 00:15:44,000
He's almost ready to give up when he hears her whistle.

292
00:15:44,000 --> 00:15:48,000
So let's say she blows her whistle at 63 minutes? Does that sound reasonable?

293
00:15:48,000 --> 00:15:49,000
Yeah, perfect.

294
00:15:49,000 --> 00:15:52,000
Cue Dr. Frankin Heinemann.

295
00:15:52,000 --> 00:15:57,000
It's like I just picked up all of my blood veins and laid them on the table.

296
00:15:57,000 --> 00:16:01,000
All this plumbing right here is the cardiovascular system of our dummy.

297
00:16:01,000 --> 00:16:07,000
Now the idea is to supply the same amount of heat to this dummy as your metabolism supplies you.

298
00:16:07,000 --> 00:16:12,000
So to do that, we're going to have a reservoir of blood, which is basically water.

299
00:16:12,000 --> 00:16:17,000
That water will be picked up by this pump and pumped into the intake of our vascular system here.

300
00:16:17,000 --> 00:16:19,000
It's alive!

301
00:16:19,000 --> 00:16:21,000
And it'll just keep circulating.

302
00:16:21,000 --> 00:16:23,000
It's beating just like a heart.

303
00:16:23,000 --> 00:16:25,000
I'd say we're in business.

304
00:16:25,000 --> 00:16:28,000
That's the heart and pump system.

305
00:16:28,000 --> 00:16:32,000
But how will thermoman generate heat like a real human?

306
00:16:32,000 --> 00:16:37,000
The metabolism of our dummy in this case is replaced by this 300 watt fish tank heater.

307
00:16:37,000 --> 00:16:43,000
It will be able, under neutral conditions, to keep his body temperature at 98.6 degrees Fahrenheit.

308
00:16:43,000 --> 00:16:47,000
When we immerse him, however, it won't be able to keep up and his body temperature will start to drop.

309
00:16:47,000 --> 00:16:49,000
We'll monitor that on this.

310
00:16:49,000 --> 00:16:56,000
A thermocouple embedded right into the intake tube so we'll be able to see directly how quickly his body temperature drops.

311
00:16:56,000 --> 00:17:04,000
So thermoman's gelatin flesh has been poured into his human-shaped mold, surrounding and supporting his copper veins.

312
00:17:04,000 --> 00:17:06,000
And once Jamie tops that off with a head...

313
00:17:06,000 --> 00:17:09,000
Oh, look at you, you handsome devil.

314
00:17:09,000 --> 00:17:11,000
...and cracks open the mold...

315
00:17:11,000 --> 00:17:12,000
There it goes.

316
00:17:12,000 --> 00:17:13,000
Oh!

317
00:17:13,000 --> 00:17:16,000
Adam and Jamie, cyborg midwife.

318
00:17:16,000 --> 00:17:19,000
Our stand-in Jack and Rose is looking good.

319
00:17:19,000 --> 00:17:23,000
That looks creepy and upsetting and awesome all at the same time.

320
00:17:23,000 --> 00:17:30,000
And once they turn it on and the water flooding through the copper coils is at body temperature, it looks even better.

321
00:17:30,000 --> 00:17:33,000
Hey, Adam, come check this out.

322
00:17:33,000 --> 00:17:34,000
Oh!

323
00:17:34,000 --> 00:17:36,000
Look at the coils.

324
00:17:36,000 --> 00:17:39,000
That is so cool. It is totally working.

325
00:17:39,000 --> 00:17:43,000
It also looks like it's heating up the flesh around the coils.

326
00:17:43,000 --> 00:17:46,000
You can see exactly where it's heating it up.

327
00:17:46,000 --> 00:17:49,000
Well, we've got Thermoboy here up to 98.6.

328
00:17:49,000 --> 00:17:58,000
So it would seem that our cardiovascular system is up to the task of providing enough heat to our body to be equivalent to a normal human.

329
00:17:58,000 --> 00:18:00,000
Everything's working!

330
00:18:00,000 --> 00:18:02,000
Ah, that's awesome.

331
00:18:02,000 --> 00:18:04,000
Now it's time for him to go for a little swim.

332
00:18:13,000 --> 00:18:17,000
What happens when you haven't got access to waves or a green screen?

333
00:18:17,000 --> 00:18:20,000
Supposedly, we try rockets.

334
00:18:20,000 --> 00:18:23,000
But so far, surf is far from up.

335
00:18:23,000 --> 00:18:29,000
And that's the bad news for Tori, because he's desperate to test this myth himself.

336
00:18:29,000 --> 00:18:33,000
However, our team of budding rocket scientists has a plan.

337
00:18:33,000 --> 00:18:35,000
Oh, yummy!

338
00:18:35,000 --> 00:18:37,000
Alright, so it looks like our fears were confirmed.

339
00:18:37,000 --> 00:18:40,000
The big rocket just has too much of an initial hit for him to surf.

340
00:18:40,000 --> 00:18:42,000
But I want to give him the benefit of the doubt.

341
00:18:42,000 --> 00:18:45,000
Maybe he did some sort of configuration of small rockets.

342
00:18:45,000 --> 00:18:47,000
You know, that's not a bad idea.

343
00:18:47,000 --> 00:18:51,000
I mean, we could take the small rockets, configure them in a way, so we get a slow ramp up,

344
00:18:51,000 --> 00:18:53,000
and it's not too big of a thrust to knock the surfer off,

345
00:18:53,000 --> 00:18:57,000
and we could extend the ride to get that 30-second ride that the myth talks about.

346
00:18:57,000 --> 00:19:01,000
You know what? We could start by pulling you on a skateboard, faster and faster,

347
00:19:01,000 --> 00:19:05,000
and find out what the maximum acceleration is that you can hang on without falling off.

348
00:19:05,000 --> 00:19:08,000
Well, it's a great idea, and then we could use that number as our rocket threshold.

349
00:19:09,000 --> 00:19:14,000
Whenever you have to wear padding for science, things generally go horribly wrong.

350
00:19:14,000 --> 00:19:17,000
So to find out the maximum g-force that Tori can handle...

351
00:19:17,000 --> 00:19:20,000
What could possibly go wrong?

352
00:19:20,000 --> 00:19:25,000
Without falling over, they're going to yank Tori faster.

353
00:19:25,000 --> 00:19:27,000
And faster.

354
00:19:30,000 --> 00:19:32,000
Wow, that was intense.

355
00:19:32,000 --> 00:19:35,000
Until the acceleration delivers a g-force he can't handle.

356
00:19:35,000 --> 00:19:40,000
Tori acceleration at 60% capacity in 3, 2, 1.

357
00:19:43,000 --> 00:19:45,000
Whoa!

358
00:19:45,000 --> 00:19:47,000
Just like that.

359
00:19:47,000 --> 00:19:50,000
Okay, so this right here is the information from the data logger.

360
00:19:50,000 --> 00:19:55,000
Along this axis is time, and along this axis is the g-load.

361
00:19:55,000 --> 00:19:58,000
You can see here the peak is at 0.8 g's.

362
00:19:58,000 --> 00:20:04,000
So what this means is that none of our rocket tests should exceed 0.8 g's.

363
00:20:04,000 --> 00:20:07,000
That way we know that he'll be able to hang on.

364
00:20:09,000 --> 00:20:12,000
And that all means to get this myth off the ground,

365
00:20:12,000 --> 00:20:17,000
they require a surfboard rocket rig that'll have a thrust below 0.8 g's,

366
00:20:17,000 --> 00:20:22,000
but still hit the myth specified 20 miles an hour for 30 seconds.

367
00:20:22,000 --> 00:20:24,000
Rocket pulling.

368
00:20:24,000 --> 00:20:29,000
And the plan is to use several banks of smaller rockets in a series of ignitions.

369
00:20:29,000 --> 00:20:33,000
Each of these smaller rockets give us around 2 pounds of thrust.

370
00:20:33,000 --> 00:20:36,000
Now our surfer and the surfboard weigh 180 pounds,

371
00:20:36,000 --> 00:20:38,000
and we need to get that weight up to 20 miles an hour.

372
00:20:38,000 --> 00:20:42,000
So we're going to need 20 model rockets for that initial stage.

373
00:20:42,000 --> 00:20:45,000
Now if this works, then we need to continue that thrust

374
00:20:45,000 --> 00:20:47,000
because these only last for 3 seconds.

375
00:20:47,000 --> 00:20:51,000
At that point we're going to have to figure out how many rockets we need for the second stage

376
00:20:51,000 --> 00:20:54,000
and at what time that second stage needs to go off.

377
00:20:54,000 --> 00:20:57,000
With the surfboard prepped and Tori's rockets ready to roll,

378
00:20:57,000 --> 00:21:01,000
it's down to Treasure Island to find out if this myth has struck gold.

379
00:21:01,000 --> 00:21:03,000
Why does this thing weigh so much?

380
00:21:03,000 --> 00:21:05,000
Because you're a fat guy.

381
00:21:05,000 --> 00:21:08,000
So here's our somewhat complicated setup for today's experiment.

382
00:21:08,000 --> 00:21:14,000
First of all, we're going to drape a guide cable the entire length of this somewhat murky water channel.

383
00:21:14,000 --> 00:21:16,000
And we'll put the surfboard down in there.

384
00:21:16,000 --> 00:21:17,000
We have touchdown.

385
00:21:17,000 --> 00:21:19,000
And connect it up to the guide cable.

386
00:21:19,000 --> 00:21:22,000
I think I'm going to need an antibacterial shower after this.

387
00:21:22,000 --> 00:21:25,000
Next we'll install the rockets and then we're ready to go.

388
00:21:25,000 --> 00:21:27,000
We'll fire them off.

389
00:21:27,000 --> 00:21:29,000
Alright, the rockets are wired.

390
00:21:29,000 --> 00:21:33,000
To collect data, we have our onboard accelerometer and our high speed camera.

391
00:21:33,000 --> 00:21:36,000
Tori's weight equivalent is strapped to the surfboard

392
00:21:36,000 --> 00:21:39,000
and the 20 rocket stage one is ready for ignition.

393
00:21:39,000 --> 00:21:41,000
It's time for launch.

394
00:21:41,000 --> 00:21:44,000
Alright, this is acceleration test for rocket surfer.

395
00:21:44,000 --> 00:21:47,000
Alright, here we go in 3, 2, 1, fire.

396
00:21:52,000 --> 00:21:54,000
Awesome!

397
00:21:54,000 --> 00:21:58,000
My gosh, that was beautiful.

398
00:21:58,000 --> 00:22:00,000
It was a slow controlled acceleration.

399
00:22:00,000 --> 00:22:06,000
And with a peak velocity close to the 20 miles an hour they need, this myth is on the up and up.

400
00:22:06,000 --> 00:22:07,000
This is great.

401
00:22:07,000 --> 00:22:10,000
We got a measurement of 0.6 Gs on takeoff.

402
00:22:10,000 --> 00:22:12,000
That's a little bit less than our predicted model.

403
00:22:12,000 --> 00:22:19,000
But the important thing is that it's below 0.8 Gs, which means Tori will be able to hang on in that situation.

404
00:22:19,000 --> 00:22:21,000
Now it's under the two stage test.

405
00:22:21,000 --> 00:22:26,000
So now that we know how many rockets we need to push my weight 20 miles an hour, just like the myth says,

406
00:22:26,000 --> 00:22:29,000
it's time to figure out how to sustain that ride for 30 seconds.

407
00:22:29,000 --> 00:22:34,000
So what I'm going to do is take a second bake of rockets and use a time fuse to extend the ride.

408
00:22:34,000 --> 00:22:36,000
Alright, rockets are loaded.

409
00:22:37,000 --> 00:22:43,000
Alright, here we go. This is two stage rocket on the surfboard in 3, 2, 1, fire.

410
00:22:49,000 --> 00:22:52,000
That's the sound of happy rocket scientists.

411
00:22:52,000 --> 00:22:56,000
Stage one fired and produced a gentle rideable start.

412
00:22:56,000 --> 00:23:01,000
Then stage two kicked in to extend the ride, just as they'd hoped.

413
00:23:01,000 --> 00:23:04,000
So we learned two important pieces of information today.

414
00:23:04,000 --> 00:23:12,000
First, that 20 rockets is enough to give us a start up G load of 0.6 Gs, which is something that Tori should be able to ride.

415
00:23:12,000 --> 00:23:19,000
Second, we can sustain our ride and maintain our speed by delaying the firing of the next stage by two seconds.

416
00:23:20,000 --> 00:23:24,000
Now we just need to add more stages to get that 30 second ride.

417
00:23:24,000 --> 00:23:28,000
The real question is, how much fun is it going to be when I ride it?

418
00:23:35,000 --> 00:23:37,000
Welcome back. I'm Jim Cameron and this is MythBusters.

419
00:23:37,000 --> 00:23:43,000
Adam and Jamie are manning the lifeboats for the most requested tall tale that the guys have ever tackled.

420
00:23:43,000 --> 00:23:46,000
Remember kids, in order to perform science you need patience.

421
00:23:46,000 --> 00:23:49,000
Patience willing to be subjected to dangerous experiments.

422
00:23:49,000 --> 00:23:54,000
And the patient willing to take a leafily cold dip is Thermoman.

423
00:23:54,000 --> 00:23:59,000
The question is, could Rosenjak have survived on that piece of wood until rescue came?

424
00:23:59,000 --> 00:24:04,000
And it all boils down to how long the human body can stave off hypothermia.

425
00:24:04,000 --> 00:24:08,000
Now we know medically how long the human body can stave off hypothermia if it's immersed in water.

426
00:24:08,000 --> 00:24:13,000
But if you're out of the water in wet clothes and the air is the same temperature, how long then?

427
00:24:13,000 --> 00:24:18,000
Is there a difference? My intuition tells me that there is, but that's what we are testing for.

428
00:24:18,000 --> 00:24:21,000
We've got to add a little more North Atlantic.

429
00:24:21,000 --> 00:24:26,000
First we're going to immerse our fully clothed dummy in 29 degree Fahrenheit water

430
00:24:26,000 --> 00:24:29,000
and see how long it takes for him to reach hypothermia.

431
00:24:29,000 --> 00:24:33,000
Can I just tell you I'm so glad it's not me doing this test?

432
00:24:33,000 --> 00:24:37,000
Then we're going to pull him out, warm him up to his normal temperature

433
00:24:37,000 --> 00:24:42,000
and put him in his wet clothing in 29 degree Fahrenheit air

434
00:24:42,000 --> 00:24:46,000
and see how long it takes for him to reach hypothermia there.

435
00:24:46,000 --> 00:24:50,000
So that's the cold bath plan, but is it accurate?

436
00:24:53,000 --> 00:24:57,000
So what can you tell me about the climatic conditions Rosenjak were facing?

437
00:24:57,000 --> 00:25:00,000
Well it turns out there were really good records from the night of the sinking

438
00:25:00,000 --> 00:25:04,000
and the water temperature would have been hovering just below freezing.

439
00:25:04,000 --> 00:25:07,000
So around 28, 29 degrees Fahrenheit.

440
00:25:07,000 --> 00:25:08,000
Hence the icebergs?

441
00:25:08,000 --> 00:25:11,000
Yeah, exactly, but what's interesting is the air temperature was almost identical.

442
00:25:11,000 --> 00:25:17,000
So it was about 33 degrees at the time of the collision, but by the time it rose,

443
00:25:19,000 --> 00:25:24,000
by the time it rose is rescue about 3 a.m. and it come down to 29 degrees.

444
00:25:24,000 --> 00:25:27,000
So your 29 degree comparison would be right on.

445
00:25:27,000 --> 00:25:28,000
Excellent.

446
00:25:28,000 --> 00:25:32,000
So with the director's seal of approval, Jack is warm to human body temperature

447
00:25:32,000 --> 00:25:33,000
and ready for action.

448
00:25:33,000 --> 00:25:34,000
Let's go.

449
00:25:34,000 --> 00:25:37,000
The conduction of this test is going to be pretty straightforward.

450
00:25:37,000 --> 00:25:41,000
Jamie with a little assistance is going to dunk our dummy in cold North Atlantic water.

451
00:25:41,000 --> 00:25:46,000
I will be monitoring his temperature drop every 30 seconds until he's dead.

452
00:25:46,000 --> 00:25:51,000
And after 10 minutes with Thermoboy's temperature dropping significantly,

453
00:25:51,000 --> 00:25:54,000
we catch a rare glimpse of Jamie's tender side.

454
00:25:54,000 --> 00:25:56,000
How you doing there, little buddy?

455
00:25:56,000 --> 00:25:57,000
Real tender.

456
00:25:57,000 --> 00:25:59,000
Sweet cheeks.

457
00:26:00,000 --> 00:26:03,000
As you move towards 96 degrees, you're shivering.

458
00:26:03,000 --> 00:26:08,000
As you move towards 91 degrees, you're shivering violently and uncontrollably.

459
00:26:08,000 --> 00:26:13,000
All this is a good thing because that's what your body is doing to keep you warm and alive.

460
00:26:13,000 --> 00:26:19,000
As you go beyond 91 degrees, you stop shivering and that's a bad thing.

461
00:26:19,000 --> 00:26:20,000
Ow!

462
00:26:20,000 --> 00:26:22,000
That water is cold.

463
00:26:22,000 --> 00:26:25,000
Our body is at 85 degrees at this point.

464
00:26:25,000 --> 00:26:32,000
He is on a solid trajectory towards dying, experiencing almost full immobility and stupor.

465
00:26:32,000 --> 00:26:35,000
Yep, and the key symptom at this stage of hypothermia,

466
00:26:35,000 --> 00:26:41,000
loss of motor control means Jack, unable to hang onto the board, would have drowned by now.

467
00:26:41,000 --> 00:26:43,000
What's your diagnosis, Dr. Heidemann?

468
00:26:43,000 --> 00:26:44,000
He's dead.

469
00:26:44,000 --> 00:26:49,000
A diagnosis reached long before the 63-minute rescue time.

470
00:26:49,000 --> 00:26:53,000
So far, so good for the survival times portrayed in the movie.

471
00:26:53,000 --> 00:26:58,000
Remember, kids, the only difference between screwing around and science is writing it down.

472
00:26:58,000 --> 00:27:04,000
Now, with Thermoman warm back up to body temperature, what about survival on the board?

473
00:27:04,000 --> 00:27:06,000
Three, two, one, here we go.

474
00:27:06,000 --> 00:27:12,000
Out of the water, in 29-degree air, would Rose have survived to die warm in her bed?

475
00:27:12,000 --> 00:27:19,000
If Jack could have got on board, would there have been a happy ending to the biggest disaster movie of all time?

476
00:27:20,000 --> 00:27:25,000
This is interesting. In 23 minutes, our guy out of the water is at 90.7 degrees.

477
00:27:25,000 --> 00:27:29,000
At the same time, in the cold water, he was at 90 degrees.

478
00:27:29,000 --> 00:27:32,000
So we're pretty much almost neck and neck between both tests.

479
00:27:32,000 --> 00:27:40,000
So, in terms of retaining heat, there's only the slightest advantage to being on the board, except in one crucial respect.

480
00:27:40,000 --> 00:27:44,000
I should point out that Thermoboy has just passed the 85-degree mark,

481
00:27:44,000 --> 00:27:48,000
which is the point that he would be in a stupor and in a mobile.

482
00:27:48,000 --> 00:27:51,000
That means that if he was in the water, he'd probably drown.

483
00:27:51,000 --> 00:27:54,000
But he's not. He's on a board. He's in air.

484
00:27:54,000 --> 00:27:58,000
So he's got kind of a grace period here where he's not dead yet.

485
00:27:58,000 --> 00:28:02,000
He's got a few degrees to go before that happens. He might get rescued.

486
00:28:02,000 --> 00:28:06,000
Yup, below 82 degrees, death is a deadly certainty.

487
00:28:06,000 --> 00:28:11,000
But at the time of rescue, Thermoman's core temperature was above that.

488
00:28:11,000 --> 00:28:18,000
So, again, the movie is accurate. Rose would have been alive just barely when the lifeboat arrived.

489
00:28:18,000 --> 00:28:20,000
So what do we take away from all this?

490
00:28:20,000 --> 00:28:26,000
Well, if you're in subzero water and weather, the difference between being in that water or out of it and wet is pretty small,

491
00:28:26,000 --> 00:28:29,000
but there is an advantage to being out of the water.

492
00:28:29,000 --> 00:28:34,000
And, critically, once you pass 85 degrees core body temperature, you can no longer move your limbs.

493
00:28:34,000 --> 00:28:39,000
If you're in the water when that happens, you are nothing but a weight heading to the bottom of the sea.

494
00:28:39,000 --> 00:28:45,000
If you are on your board or boat or whatever you've got, you might just last until rescue.

495
00:28:45,000 --> 00:28:49,000
Quite simply, Jack's only chance of survival is to get on the board.

496
00:28:49,000 --> 00:28:51,000
But could he?

497
00:28:51,000 --> 00:28:53,000
There's only one way to answer that question.

498
00:28:53,000 --> 00:28:58,000
Adam and Janie are getting wet and intimate for science.

499
00:28:58,000 --> 00:29:01,000
Next on Mythbusters...

500
00:29:01,000 --> 00:29:03,000
What could possibly go wrong?

501
00:29:03,000 --> 00:29:07,000
Is Tori really going to ride a rocket-powered surfboard?

502
00:29:10,000 --> 00:29:13,000
Please, don't try what you're about to see at home.

503
00:29:13,000 --> 00:29:15,000
We're surrounded by experts that keep us safe.

504
00:29:15,000 --> 00:29:17,000
We get hurt so you don't have to.

505
00:29:21,000 --> 00:29:27,000
Is it true with no waves in sight, you can power a surfboard with a rocket?

506
00:29:27,000 --> 00:29:34,000
Resident human Crash Test dummy, that's Tori under the afro, is ready and willing to find out.

507
00:29:34,000 --> 00:29:39,000
So it's off to the perfect location, Quarry Lakes Regional Parks.

508
00:29:39,000 --> 00:29:42,000
I'm a little nervous, what if the scene blows up?

509
00:29:42,000 --> 00:29:49,000
For the maiden launch of Bellachy's Bodacious Board, a board that has been extensively modified.

510
00:29:49,000 --> 00:29:51,000
Keel weight is installed.

511
00:29:51,000 --> 00:29:56,000
We have a steel protective box so that our surfer won't get hit with any of the rocket flame.

512
00:29:56,000 --> 00:30:02,000
We have altered the shape of the surfboard, giving a little junk in the trunk to give us added stability of the way that outriggers would.

513
00:30:02,000 --> 00:30:08,000
On the bottom, we've got a strake going along the board that will keep us in a nice straight line and not toss our surfer off.

514
00:30:08,000 --> 00:30:11,000
We also have a weighted keel for extra stability.

515
00:30:14,000 --> 00:30:17,000
So this is the rocket bank. We have over 200 rockets.

516
00:30:17,000 --> 00:30:19,000
The first bank of 30 will go off.

517
00:30:19,000 --> 00:30:23,000
Now that'll get the surfer going so it doesn't just shoot from underneath his feet.

518
00:30:23,000 --> 00:30:26,000
Now after that happens, there's a fuse that runs through the rest of the rocket.

519
00:30:26,000 --> 00:30:30,000
So every 2 1.5 seconds, another bank of 15 will go off.

520
00:30:30,000 --> 00:30:35,000
Keep the speed steady and to extend the ride to 30 seconds at 20 miles an hour.

521
00:30:35,000 --> 00:30:39,000
So it's the non-human crash test dummy that will be stepping up first.

522
00:30:39,000 --> 00:30:42,000
The team has to know it's going to be safe for Tori.

523
00:30:42,000 --> 00:30:44,000
He looks excited about this one.

524
00:30:44,000 --> 00:30:46,000
Same setup as before.

525
00:30:46,000 --> 00:30:53,000
Rail system out on the water, electric match to remotely ignite it from a safe distance and we'll see what happens.

526
00:30:53,000 --> 00:30:56,000
Alright, we're wired. Let's launch this guy.

527
00:30:56,000 --> 00:30:59,000
If it's safe, then it's Tori time.

528
00:31:00,000 --> 00:31:04,000
Okay, here we go. This is Buster Rocket Surf.

529
00:31:04,000 --> 00:31:07,000
In 3, 2, 1...

530
00:31:10,000 --> 00:31:12,000
Good launch, good launch!

531
00:31:12,000 --> 00:31:14,000
Look at that, look at that!

532
00:31:18,000 --> 00:31:20,000
That was awesome!

533
00:31:21,000 --> 00:31:25,000
Buster's Rocket Surf was an epic ride.

534
00:31:25,000 --> 00:31:27,000
That totally worked! That's awesome!

535
00:31:27,000 --> 00:31:30,000
He didn't fall in, he served it!

536
00:31:30,000 --> 00:31:35,000
Just that last jump made it a little scary to actually think Tori's going to be on the board.

537
00:31:36,000 --> 00:31:38,000
I think it's time I suit up.

538
00:31:38,000 --> 00:31:40,000
I think so!

539
00:31:40,000 --> 00:31:44,000
I've already picked out a really nice bouquet to bring to him in the hospital.

540
00:31:44,000 --> 00:31:47,000
And I'm sure there are not that many stitches involved.

541
00:31:47,000 --> 00:31:48,000
I know!

542
00:31:51,000 --> 00:31:55,000
Welcome back. This is MythBusters and this is James Frickin' Cameron.

543
00:31:55,000 --> 00:31:57,000
I am indeed James Frickin' Cameron.

544
00:31:57,000 --> 00:32:00,000
We've been testing a very controversial story here.

545
00:32:00,000 --> 00:32:05,000
At the end of the movie Titanic, could Jack and Rose both have gotten onto the board and survived?

546
00:32:05,000 --> 00:32:09,000
So we conducted some small scale tests here in a tub in the shop.

547
00:32:09,000 --> 00:32:11,000
Jeez, and crow, Jack.

548
00:32:11,000 --> 00:32:14,000
And at that point, it was looking pretty good for my movie.

549
00:32:14,000 --> 00:32:17,000
Yeah, they may extensively tested hypothermia.

550
00:32:17,000 --> 00:32:19,000
What's your diagnosis, Dr. Heidemann?

551
00:32:19,000 --> 00:32:20,000
He's dead.

552
00:32:20,000 --> 00:32:22,000
So again, the movie's right.

553
00:32:22,000 --> 00:32:26,000
Jack in the water would have died before a rescue got there,

554
00:32:26,000 --> 00:32:29,000
and Rose out of the water could have held on.

555
00:32:29,000 --> 00:32:31,000
So, it's myth confirmed, right?

556
00:32:31,000 --> 00:32:33,000
Not just yet.

557
00:32:33,000 --> 00:32:36,000
We almost never call it based on the scale tests alone.

558
00:32:36,000 --> 00:32:38,000
The ultimate test is always full scale.

559
00:32:38,000 --> 00:32:42,000
Okay, full scale, but the actors are no longer available, so...

560
00:32:42,000 --> 00:32:44,000
You're going to be Jack. You're going to be Rose.

561
00:32:44,000 --> 00:32:45,000
Yes!

562
00:32:45,000 --> 00:32:47,000
Wait a second, I have a problem with this.

563
00:32:47,000 --> 00:32:48,000
What?

564
00:32:48,000 --> 00:32:49,000
We weigh more than Jack and Rose.

565
00:32:49,000 --> 00:32:51,000
Ah, you're going to be Jack.

566
00:32:51,000 --> 00:32:52,000
You're going to be Rose.

567
00:32:52,000 --> 00:32:53,000
Ah, you're totally right.

568
00:32:53,000 --> 00:32:55,000
Well, look, we got to build a board anyway,

569
00:32:55,000 --> 00:32:58,000
so let's scale up its buoyancy to adjust for our increased mass,

570
00:32:58,000 --> 00:33:00,000
and then we'll put it to the test once and for all.

571
00:33:00,000 --> 00:33:01,000
Are you ready, Rose?

572
00:33:01,000 --> 00:33:02,000
Don't call me Rose.

573
00:33:02,000 --> 00:33:03,000
Sorry.

574
00:33:03,000 --> 00:33:06,000
So, it's crunch time for Cameron's Conundrum.

575
00:33:06,000 --> 00:33:08,000
Off the shores of Treasure Island,

576
00:33:08,000 --> 00:33:13,000
will Rose Heidemann and Jack Savage both get on board the board,

577
00:33:13,000 --> 00:33:15,000
and both survive until rescue.

578
00:33:15,000 --> 00:33:17,000
And speaking of the board...

579
00:33:17,000 --> 00:33:20,000
We've had this thing carefully crafted to be an accurate replica

580
00:33:20,000 --> 00:33:24,000
of what was in the movie, based on designs provided by the Maritime Museum

581
00:33:24,000 --> 00:33:25,000
of Nova Scotia.

582
00:33:25,000 --> 00:33:30,000
It's the same material, same size, it's what we're going to use.

583
00:33:30,000 --> 00:33:34,000
Next, it's over to the wardrobe department to get dressed for the occasion.

584
00:33:34,000 --> 00:33:36,000
Let's go swimming.

585
00:33:36,000 --> 00:33:41,000
In addition to this, I'm going to be wearing this Cork and Canvas replica life preserver,

586
00:33:41,000 --> 00:33:45,000
which Adam sewed up, and it's exactly like what they had in the movie.

587
00:33:45,000 --> 00:33:48,000
Indeed, it's a period-accurate piece,

588
00:33:48,000 --> 00:33:53,000
made of the same materials and with the same buoyancy as the one Rose was wearing.

589
00:33:53,000 --> 00:33:58,000
And speaking of accuracy, Jamie has finessed the floating question.

590
00:33:58,000 --> 00:34:00,000
So, the board matches the movie, but we don't.

591
00:34:00,000 --> 00:34:01,000
We're heavier, obviously.

592
00:34:01,000 --> 00:34:06,000
So, we're adjusting the board to give it the same amount of lift and stability that it does for Rose.

593
00:34:06,000 --> 00:34:10,000
According to our math, we need to make it 11% more buoyant.

594
00:34:10,000 --> 00:34:13,000
However, we're not just relying on a number.

595
00:34:13,000 --> 00:34:14,000
We'll know we've got it right.

596
00:34:14,000 --> 00:34:19,000
It visually, me on the board, matches Rose on the board in the movie.

597
00:34:19,000 --> 00:34:20,000
And why do you know?

598
00:34:20,000 --> 00:34:23,000
It does, which means they're in business.

599
00:34:27,000 --> 00:34:30,000
Meaning the myth is ready to sink or swim.

600
00:34:30,000 --> 00:34:33,000
All right, Jamie, you ready for me to start the timer and start this test?

601
00:34:33,000 --> 00:34:34,000
Go ahead.

602
00:34:34,000 --> 00:34:38,000
Okay, 63 minutes till rescue starts.

603
00:34:38,000 --> 00:34:39,000
Now.

604
00:34:39,000 --> 00:34:41,000
Okay, Rose.

605
00:34:42,000 --> 00:34:44,000
I mean, Jamie, sorry.

606
00:34:44,000 --> 00:34:47,000
Let's see if we can both get on this thing.

607
00:34:47,000 --> 00:34:51,000
As the small scale test predicted, it's not looking great.

608
00:34:57,000 --> 00:35:05,000
With Jack Savage struggling to stabilize himself and the board, the myth looks destined for a watery grave.

609
00:35:05,000 --> 00:35:06,000
Ha ha ha ha.

610
00:35:35,000 --> 00:35:36,000
It's looking good.

611
00:35:36,000 --> 00:35:39,000
I think we might actually have a rocket test coming.

612
00:35:39,000 --> 00:35:41,000
The stability is good.

613
00:35:41,000 --> 00:35:42,000
Let's go for it.

614
00:35:42,000 --> 00:35:43,000
Yeah.

615
00:36:05,000 --> 00:36:07,000
I'm not sure if we can get on the board.

616
00:36:07,000 --> 00:36:08,000
We're going to get on the board.

617
00:36:08,000 --> 00:36:09,000
We're going to get on the board.

618
00:36:09,000 --> 00:36:10,000
We're going to get on the board.

619
00:36:10,000 --> 00:36:11,000
We're going to get on the board.

620
00:36:11,000 --> 00:36:12,000
We're going to get on the board.

621
00:36:12,000 --> 00:36:13,000
We're going to get on the board.

622
00:36:13,000 --> 00:36:14,000
We're going to get on the board.

623
00:36:14,000 --> 00:36:15,000
We're going to get on the board.

624
00:36:15,000 --> 00:36:16,000
We're going to get on the board.

625
00:36:16,000 --> 00:36:17,000
We're going to get on the board.

626
00:36:17,000 --> 00:36:18,000
We're going to get on the board.

627
00:36:18,000 --> 00:36:19,000
We're going to get on the board.

628
00:36:19,000 --> 00:36:20,000
We're going to get on the board.

629
00:36:20,000 --> 00:36:21,000
We're going to get on the board.

630
00:36:21,000 --> 00:36:22,000
We're going to get on the board.

631
00:36:22,000 --> 00:36:23,000
We're going to get on the board.

632
00:36:23,000 --> 00:36:24,000
We're going to get on the board.

633
00:36:24,000 --> 00:36:25,000
We're going to get on the board.

634
00:36:25,000 --> 00:36:29,000
But I have to say, I wouldn't trade this moment for anything.

635
00:36:29,000 --> 00:36:32,000
To be on a surfboard powered by a rocket,

636
00:36:32,000 --> 00:36:34,000
this is going to be the best day ever.

637
00:36:36,000 --> 00:36:38,000
Belayche Wad, this is control.

638
00:36:38,000 --> 00:36:40,000
Take your position on board the board.

639
00:36:40,000 --> 00:36:42,000
You are go for launch.

640
00:36:42,000 --> 00:36:44,000
We're getting close to being ready.

641
00:36:44,000 --> 00:36:46,000
System's check is complete.

642
00:36:46,000 --> 00:36:48,000
You are cleared for takeoff.

643
00:36:48,000 --> 00:36:51,000
This is rocket surf for final experiment.

644
00:36:51,000 --> 00:36:52,000
Rock the rocket!

645
00:36:52,000 --> 00:36:54,000
Go, go, go!

646
00:36:54,000 --> 00:36:58,000
In three, two, one.

647
00:36:58,000 --> 00:37:00,000
Ignition.

648
00:37:00,000 --> 00:37:02,000
We have liftoff.

649
00:37:11,000 --> 00:37:12,000
You okay?

650
00:37:12,000 --> 00:37:14,000
Man down. Man down.

651
00:37:16,000 --> 00:37:19,000
Now, you can't keep Belayche down for long.

652
00:37:19,000 --> 00:37:21,000
That was one incredible ride.

653
00:37:21,000 --> 00:37:24,000
The acceleration was insane.

654
00:37:24,000 --> 00:37:28,000
I did it! I rode the rocket surfboard!

655
00:37:28,000 --> 00:37:31,000
Everything didn't go exactly according to plan.

656
00:37:31,000 --> 00:37:33,000
Some of the rocket banks went off too early.

657
00:37:33,000 --> 00:37:36,000
Meaning he didn't have that nice, slow acceleration we hoped for,

658
00:37:36,000 --> 00:37:40,000
but a little bit more of a hold on for dear life kind of ride.

659
00:37:43,000 --> 00:37:45,000
That was awesome!

660
00:37:45,000 --> 00:37:47,000
Rock it, sir!

661
00:37:47,000 --> 00:37:48,000
But he still did it.

662
00:37:48,000 --> 00:37:52,000
He held on to the almost bitter end before he fell off.

663
00:37:52,000 --> 00:37:54,000
That was insane!

664
00:37:54,000 --> 00:37:55,000
You did it!

665
00:37:55,000 --> 00:37:57,000
It literally happened so quick.

666
00:37:57,000 --> 00:37:59,000
I was like, I was trying to get my balance,

667
00:37:59,000 --> 00:38:01,000
and I hit the switch, and before I knew it,

668
00:38:01,000 --> 00:38:03,000
I was looking at the whole lake.

669
00:38:03,000 --> 00:38:05,000
It was crazy!

670
00:38:06,000 --> 00:38:11,000
Crazy, incredibly lucky, and a brilliant feat of engineering.

671
00:38:12,000 --> 00:38:15,000
This is one of those experiments where a hundred things have to go right

672
00:38:15,000 --> 00:38:17,000
in order for you to be successful.

673
00:38:17,000 --> 00:38:21,000
Getting that 30-second, 20-mile-per-hour ride is a very difficult problem,

674
00:38:21,000 --> 00:38:23,000
mostly because of the rockets.

675
00:38:23,000 --> 00:38:25,000
They're heavy. They have a high center of gravity.

676
00:38:25,000 --> 00:38:28,000
The timing is critical. You don't have a lot of space.

677
00:38:29,000 --> 00:38:33,000
Having said that, I feel like we all need to go buy some lottery tickets,

678
00:38:33,000 --> 00:38:36,000
because that could have been disastrous, but it went exceptionally well.

679
00:38:36,000 --> 00:38:40,000
And with that, it's back to the shop to wrap it up.

680
00:38:40,000 --> 00:38:42,000
I think we should supersize this.

681
00:38:43,000 --> 00:38:45,000
That was awesome.

682
00:38:45,000 --> 00:38:46,000
It was so much fun.

683
00:38:46,000 --> 00:38:48,000
All right, so how are we going to call this one?

684
00:38:48,000 --> 00:38:51,000
Well, I did ride a rocket-powered surfboard, so can't we call it plausible?

685
00:38:51,000 --> 00:38:53,000
Based on our parameters, I checked the high speed.

686
00:38:53,000 --> 00:38:55,000
You didn't quite make it to 20 miles an hour.

687
00:38:55,000 --> 00:38:57,000
And you didn't have a full 30-second ride.

688
00:38:57,000 --> 00:38:59,000
And there's the fact that we had to use multiple rockets

689
00:38:59,000 --> 00:39:02,000
instead of the one rocket like the myth talks about.

690
00:39:02,000 --> 00:39:05,000
Yeah, so based on technicalities, this one is busted.

691
00:39:05,000 --> 00:39:08,000
All right, it's busted. Man, that was one dangerous experiment.

692
00:39:08,000 --> 00:39:11,000
Needless to say, do not try this one at home.

693
00:39:16,000 --> 00:39:20,000
Want to know why we did what we did and didn't do what we didn't do?

694
00:39:20,000 --> 00:39:25,000
Go to discovery.com slash mythbusters after show and see why.

695
00:39:28,000 --> 00:39:30,000
You ready to start this test?

696
00:39:30,000 --> 00:39:32,000
Okay, Rose. I mean, Jamie.

697
00:39:32,000 --> 00:39:34,000
All right, let's see.

698
00:39:34,000 --> 00:39:37,000
Here we can both get on this thing.

699
00:39:37,000 --> 00:39:42,000
Will Adam and Jamie's Titanic tail be consigned to Davy Jones Locker?

700
00:39:42,000 --> 00:39:47,000
Jack's first attempts to get aboard the board seem very similar to the movie.

701
00:39:47,000 --> 00:39:51,000
The board does appear to be only made for one.

702
00:39:54,000 --> 00:39:58,000
But once they stabilize and get their balance, things are looking up.

703
00:39:58,000 --> 00:40:02,000
All right, all right. Baby steps. Baby steps.

704
00:40:02,000 --> 00:40:05,000
So when I first got on, it felt anything but stable.

705
00:40:05,000 --> 00:40:07,000
Just like the movie and the small scale test we did,

706
00:40:07,000 --> 00:40:09,000
it felt like it could tip at any moment.

707
00:40:09,000 --> 00:40:12,000
It's holding us up out of the water, mostly.

708
00:40:12,000 --> 00:40:15,000
And if we were in nearly freezing temperatures and danger of passing out,

709
00:40:15,000 --> 00:40:18,000
that would be a real issue. So I had an idea.

710
00:40:18,000 --> 00:40:20,000
You're wearing a life jacket.

711
00:40:20,000 --> 00:40:23,000
What say, Rose? Spread some of your buoyancy around.

712
00:40:23,000 --> 00:40:27,000
Let's put it underneath this thing and get every bit we can out of it.

713
00:40:27,000 --> 00:40:32,000
And it's the MacGyver style tweak that really puts the nail in this myth's coffin.

714
00:40:32,000 --> 00:40:35,000
The additional buoyancy has made a massive difference.

715
00:40:35,000 --> 00:40:39,000
They're no longer floundering around but sitting pretty.

716
00:40:39,000 --> 00:40:44,000
In fact, so pretty that Rose is ready to nap her way to the 63-minute rescue.

717
00:40:44,000 --> 00:40:48,000
80% of my body is out of the water and in the air.

718
00:40:48,000 --> 00:40:53,000
Yeah, same here. If we can hold this sort of stationery, I think we're golden.

719
00:40:53,000 --> 00:40:56,000
Jamie, we're almost there. 15 seconds.

720
00:40:56,000 --> 00:41:00,000
Well, you know, however noble Jackson tensions might have been,

721
00:41:00,000 --> 00:41:03,000
sometimes discretion is the better part of valor.

722
00:41:03,000 --> 00:41:05,000
Hang on, Rose!

723
00:41:05,000 --> 00:41:10,000
With all we've learned, I think Jack's death was needless.

724
00:41:13,000 --> 00:41:14,000
Don't call me Rose.

725
00:41:14,000 --> 00:41:19,000
Sorry. The key fact is we're rescued.

726
00:41:19,000 --> 00:41:26,000
We totally made it on top of the board with most of our bodies out of the water in 63 minutes.

727
00:41:27,000 --> 00:41:31,000
All right, James, we have some good news and we have some bad news.

728
00:41:31,000 --> 00:41:33,000
All right, give me the good news.

729
00:41:33,000 --> 00:41:36,000
Well, the good news is the movie got it right as far as hypothermia.

730
00:41:36,000 --> 00:41:41,000
Jack would have drowned and Rose would have been able to hang on long enough to be rescued.

731
00:41:41,000 --> 00:41:48,000
The bad news is based on our experiments, we have to find that they both could have survived on that board.

732
00:41:48,000 --> 00:41:49,000
Really?

733
00:41:49,000 --> 00:41:57,000
There were a couple of things and the first was that we were able to retie the life preserver that Rose was wearing underneath the board.

734
00:41:57,000 --> 00:41:59,000
And that gave it more buoyancy.

735
00:41:59,000 --> 00:42:06,000
And we were able to prop up our bodies on the board so that most of our body mass was actually outside of the water.

736
00:42:06,000 --> 00:42:10,000
Based on that, we've got to say this is plausible. Rose and Jack could have survived.

737
00:42:11,000 --> 00:42:13,000
I think you guys are missing the point here.

738
00:42:13,000 --> 00:42:16,000
The script says Jack dies. He has to die.

739
00:42:16,000 --> 00:42:21,000
So maybe we screwed up and the board should have been a little tiny bit smaller, but the dude's going down.

740
00:42:21,000 --> 00:42:22,000
I can't argue with that.

741
00:42:22,000 --> 00:42:23,000
No.

742
00:42:29,000 --> 00:42:31,000
You
