1
00:00:00,000 --> 00:00:07,000
Remember, do not try anything you are about to see at home.

2
00:00:07,000 --> 00:00:22,000
On this salivating episode of Mythbusters, Adam and Jamie regurgitate a Seinfeld classic.

3
00:00:22,000 --> 00:00:23,000
I'm sorry.

4
00:00:23,000 --> 00:00:26,000
Is double dipping really germ warfare?

5
00:00:27,000 --> 00:00:36,000
Plus, they're falling over themselves, finding out if a banana peel is a guaranteed slapstick wipeout.

6
00:00:36,000 --> 00:00:38,000
I've never seen him like that.

7
00:00:38,000 --> 00:00:49,000
Meanwhile, Harry Grant and Tori have a blast and cook up trouble as they tackle the myth of homemade diamonds.

8
00:00:49,000 --> 00:00:51,000
I'm gonna be rich.

9
00:00:51,000 --> 00:01:00,000
So prepare yourselves. There's thrills, spills and the biggest explosion in Mythbusters history.

10
00:01:06,000 --> 00:01:08,000
Who are the Mythbusters?

11
00:01:08,000 --> 00:01:10,000
Adam Savage.

12
00:01:10,000 --> 00:01:12,000
Oh, check out my new bulletproof vest, man!

13
00:01:12,000 --> 00:01:13,000
And Jamie Heineman.

14
00:01:13,000 --> 00:01:15,000
I usually don't let people do that.

15
00:01:15,000 --> 00:01:19,000
Between them more than 30 years of special effects experience.

16
00:01:19,000 --> 00:01:21,000
I'm not gonna get tired of that.

17
00:01:21,000 --> 00:01:25,000
Joining them, Grant Imahara.

18
00:01:25,000 --> 00:01:27,000
You beauty!

19
00:01:27,000 --> 00:01:28,000
Tori Bellachy.

20
00:01:31,000 --> 00:01:32,000
And Carrie Byron.

21
00:01:32,000 --> 00:01:34,000
The question out of here, see?

22
00:01:34,000 --> 00:01:38,000
They don't just tell the myths, they put them to the test.

23
00:01:50,000 --> 00:01:54,000
Dare I ask why we're juggling bananas?

24
00:01:54,000 --> 00:01:58,000
It's because of one of the oldest gags and slapstick comedy that we're gonna test.

25
00:01:58,000 --> 00:02:05,000
That every banana peel left on the ground equals someone walking up to it and slipping and falling flat on their keystone.

26
00:02:05,000 --> 00:02:07,000
The old slipping on a banana peel routine.

27
00:02:07,000 --> 00:02:08,000
Exactly.

28
00:02:10,000 --> 00:02:17,000
According to the laws of comedy, a discarded banana peel is an unavoidable fall magnet.

29
00:02:18,000 --> 00:02:21,000
But is the peel really a guaranteed guffaw?

30
00:02:21,000 --> 00:02:24,000
Or is it a load of shtick?

31
00:02:26,000 --> 00:02:27,000
Such a lovely display.

32
00:02:27,000 --> 00:02:28,000
Thank you.

33
00:02:28,000 --> 00:02:29,000
Where do you think we should start?

34
00:02:29,000 --> 00:02:36,000
I'm gonna go out on a limb here and say I think we should peel one of these, put it out on the floor, try slipping on it.

35
00:02:36,000 --> 00:02:39,000
No need to overcomplicate things, let's go.

36
00:02:39,000 --> 00:02:40,000
Alright.

37
00:02:40,000 --> 00:02:49,000
So to find out if a banana peel can topple the Heinemann, Jamie slips into something more comfortable while Adam checks his insurance.

38
00:02:49,000 --> 00:02:50,000
Yes.

39
00:02:50,000 --> 00:02:51,000
No, one banana.

40
00:02:51,000 --> 00:02:54,000
Only one, I'm just gonna place one banana, yeah, he'll be blindfolded.

41
00:02:54,000 --> 00:02:58,000
Well, it's just to see if he's gonna slip, you know, if one banana equals one person slipping.

42
00:02:58,000 --> 00:02:59,000
Yeah, exactly.

43
00:02:59,000 --> 00:03:01,000
Okay, I'll see after it's done.

44
00:03:02,000 --> 00:03:03,000
That's the plan.

45
00:03:03,000 --> 00:03:10,000
And a blindfolded Jamie won't be able to see the peel, meaning gravity can take its hilarious revenge.

46
00:03:10,000 --> 00:03:13,000
You're just gonna take a leisurely walk forward.

47
00:03:16,000 --> 00:03:17,000
Alright, stop.

48
00:03:20,000 --> 00:03:24,000
But unlike in the movies, Jamie's not hitting his mark.

49
00:03:26,000 --> 00:03:29,000
Until finally, bingo.

50
00:03:29,000 --> 00:03:32,000
You step right on it, nothing happened.

51
00:03:33,000 --> 00:03:37,000
And that's not quite the result the guys were expecting.

52
00:03:37,000 --> 00:03:44,000
So I could peel the banana peel when I finally stepped on it, but, you know, you feel something like that you compensate for.

53
00:03:44,000 --> 00:03:49,000
At no time did I feel like I was gonna lose it and also end up on my butt.

54
00:03:49,000 --> 00:03:55,000
The Heinemann may be stealthy enough to avoid one peel, but surely there's no escaping a fall now.

55
00:03:55,000 --> 00:04:05,000
This gauntlet of banana peels with their leathery tops and their slippery bottoms is a virtual lethal gauntlet of slipping and falling.

56
00:04:05,000 --> 00:04:07,000
Let's see how the Heinemann does.

57
00:04:09,000 --> 00:04:10,000
Go for it.

58
00:04:10,000 --> 00:04:15,000
But gauntlet or no gauntlet, Jamie remains unfazed.

59
00:04:15,000 --> 00:04:22,000
I think what I need to do from here is actually move quickly enough that it doesn't matter whether I know it's coming or not.

60
00:04:22,000 --> 00:04:24,000
If I slip, I'm gonna fall.

61
00:04:26,000 --> 00:04:31,000
And even at full speed, there's still no banana.

62
00:04:31,000 --> 00:04:32,000
Good job.

63
00:04:32,000 --> 00:04:34,000
Oh, it's not looking good for this mint.

64
00:04:34,000 --> 00:04:36,000
Can I take this off now?

65
00:04:36,000 --> 00:04:37,000
Yes, you can.

66
00:04:39,000 --> 00:04:40,000
That's better.

67
00:04:40,000 --> 00:04:42,000
Yeah, mustache is all funky.

68
00:04:44,000 --> 00:04:45,000
That's better.

69
00:04:46,000 --> 00:04:48,000
Well, one banana, no slip.

70
00:04:48,000 --> 00:04:50,000
Ten bananas, little bit of slip.

71
00:04:50,000 --> 00:04:52,000
Nothing spectacular, even when running.

72
00:04:52,000 --> 00:05:00,000
So I think we need to do some testing and find out just how slippery these things actually are when compared to other slippery things.

73
00:05:00,000 --> 00:05:04,000
And that means it's time to get scientific.

74
00:05:04,000 --> 00:05:07,000
There's two kinds of friction we want to look at here.

75
00:05:07,000 --> 00:05:11,000
One is called static friction, and that's from a stop to a start.

76
00:05:11,000 --> 00:05:19,000
There's a secondary one, which is dynamic or kinetic friction, which is how much resistance the banana peel has to moving while it's moving.

77
00:05:19,000 --> 00:05:26,000
And I'm gonna build some rigs to test both and compare banana peels to some other slippery things.

78
00:05:27,000 --> 00:05:28,000
Let's get this straight.

79
00:05:28,000 --> 00:05:32,000
When you slip on a peel, there are two types of friction in play.

80
00:05:32,000 --> 00:05:38,000
First is the static friction, which the banana peel must overcome to start moving.

81
00:05:38,000 --> 00:05:43,000
And then once in motion, kinetic friction is the peel's resistance to sliding.

82
00:05:43,000 --> 00:05:48,000
And first, to test static friction, Adam's whipped up just the thing.

83
00:05:48,000 --> 00:05:54,000
Let's start with this shoe and four pounds of weight in it and see what its static friction angle is.

84
00:05:54,000 --> 00:05:55,000
Okay.

85
00:05:55,000 --> 00:05:56,000
Ten.

86
00:05:56,000 --> 00:05:57,000
Twenty.

87
00:05:57,000 --> 00:05:59,000
Forty-five.

88
00:05:59,000 --> 00:06:02,000
Forty-five degrees for the shoe.

89
00:06:02,000 --> 00:06:04,000
That's the control.

90
00:06:04,000 --> 00:06:07,000
And with the banana peel, ten.

91
00:06:07,000 --> 00:06:08,000
Fifteen.

92
00:06:08,000 --> 00:06:10,000
There it is.

93
00:06:10,000 --> 00:06:12,000
Yep, fifteen degrees.

94
00:06:12,000 --> 00:06:16,000
So the peel cuts the static friction by a factor of three.

95
00:06:16,000 --> 00:06:19,000
What's slicker than a banana peel?

96
00:06:19,000 --> 00:06:24,000
Well, I happen to have some animal birthing agent laying around.

97
00:06:24,000 --> 00:06:33,000
By comparing them with this super slick lube, the boys can work out where the banana peel sits on the, uh, slipperiness scale.

98
00:06:33,000 --> 00:06:35,000
Okay.

99
00:06:35,000 --> 00:06:41,000
Five, ten, fifteen, twenty.

100
00:06:41,000 --> 00:06:44,000
I was gonna stop it, but I didn't want to touch it.

101
00:06:45,000 --> 00:06:48,000
The physics of this slapstick myth are looking good.

102
00:06:48,000 --> 00:06:53,000
Surprisingly, the static friction of the banana peel is lower than the lube.

103
00:06:53,000 --> 00:06:56,000
However, there's one more thing to test.

104
00:06:56,000 --> 00:06:59,000
And that's the kinetic friction.

105
00:06:59,000 --> 00:07:06,000
This is a device for measuring just that, the amount of force it takes to pull it once you've overcome the static friction.

106
00:07:06,000 --> 00:07:09,000
Once again, the shoe is their baseline.

107
00:07:09,000 --> 00:07:12,000
Jamie gives it a nudge to get it moving.

108
00:07:14,000 --> 00:07:16,000
I'd call it about fourteen pounds.

109
00:07:16,000 --> 00:07:18,000
That looks about right to me.

110
00:07:18,000 --> 00:07:21,000
But with the banana peel, that number halves.

111
00:07:23,000 --> 00:07:25,000
Seven pounds.

112
00:07:26,000 --> 00:07:28,000
Finally, it's the slippery lube.

113
00:07:28,000 --> 00:07:30,000
That is nasty.

114
00:07:30,000 --> 00:07:31,000
Go for it.

115
00:07:31,000 --> 00:07:32,000
And go.

116
00:07:33,000 --> 00:07:36,000
That was consistently five across the whole thing.

117
00:07:36,000 --> 00:07:38,000
So that takes care of the data.

118
00:07:38,000 --> 00:07:40,000
But what does it all mean?

119
00:07:40,000 --> 00:07:43,000
The banana peel is not the slipperiest thing we could find.

120
00:07:43,000 --> 00:07:48,000
We found some lubricant that's actually slipperier, but the banana peel did prospectively.

121
00:07:48,000 --> 00:07:53,000
However, I don't feel like we can call this one until we test it full size, of course.

122
00:07:53,000 --> 00:07:55,000
Where do we go from here?

123
00:07:55,000 --> 00:08:00,000
Well, you know, it's funny. With all the testing we've done so far, we still have yet to see anyone slip.

124
00:08:00,000 --> 00:08:03,000
So what you're saying is somebody needs to fall on their ass?

125
00:08:03,000 --> 00:08:06,000
Absolutely, but we're gonna need some more bananas.

126
00:08:06,000 --> 00:08:08,000
Lots more bananas.

127
00:08:08,000 --> 00:08:09,000
Yeah.

128
00:08:10,000 --> 00:08:11,000
Yeah.

129
00:08:16,000 --> 00:08:18,000
What's up with the bling?

130
00:08:18,000 --> 00:08:21,000
We did Robin and Dewey car. Yeah.

131
00:08:21,000 --> 00:08:23,000
Nah, just kidding. It's for our next man.

132
00:08:23,000 --> 00:08:25,000
Okay, why?

133
00:08:25,000 --> 00:08:28,000
Because we're trying to find out if you can make diamonds.

134
00:08:28,000 --> 00:08:30,000
Aren't there companies that already do that?

135
00:08:30,000 --> 00:08:32,000
Yeah, but they're like million dollar machines.

136
00:08:32,000 --> 00:08:34,000
I mean, we're gonna do this different.

137
00:08:34,000 --> 00:08:38,000
We want to see if you can make diamonds on your own in the comfort of your own home.

138
00:08:38,000 --> 00:08:40,000
Okay, so homemade diamonds.

139
00:08:40,000 --> 00:08:45,000
Oh yeah, there's all these schemes on the internet where you can make them in your own kitchen.

140
00:08:45,000 --> 00:08:47,000
You don't need any of these fancy machines.

141
00:08:47,000 --> 00:08:49,000
And in the end, you get diamonds.

142
00:08:49,000 --> 00:08:51,000
Yeah, we have three different techniques.

143
00:08:51,000 --> 00:08:53,000
One is using peanut butter and a microwave.

144
00:08:53,000 --> 00:08:55,000
Another one is using molten iron.

145
00:08:55,000 --> 00:09:00,000
And then finally we got one from the TV show CSI and you use nothing but graphite and a pressure cooker.

146
00:09:00,000 --> 00:09:02,000
Okay, let's put them to the test.

147
00:09:02,000 --> 00:09:03,000
We know if this works.

148
00:09:03,000 --> 00:09:05,000
In the end, we can be millionaires.

149
00:09:05,000 --> 00:09:07,000
Yeah!

150
00:09:09,000 --> 00:09:16,000
The traditional way of getting your hands on a diamond used to be either mining or marriage.

151
00:09:16,000 --> 00:09:25,000
But modern science has brought us synthetic diamonds created in labs using multi-million dollar technology.

152
00:09:25,000 --> 00:09:32,000
However, according to this myth, you can make your own precious gems, all from the comfort of your own home.

153
00:09:33,000 --> 00:09:35,000
Okay, well there are three recipes.

154
00:09:35,000 --> 00:09:38,000
So why don't we each take a technique and have a little competition?

155
00:09:38,000 --> 00:09:41,000
Okay, well in that case, let's make a winner takes all.

156
00:09:41,000 --> 00:09:44,000
Whoever makes the most diamonds with the greatest value keeps everything.

157
00:09:44,000 --> 00:09:46,000
I like a good competition.

158
00:09:46,000 --> 00:09:48,000
I'm going to put my hand up for peanut butter.

159
00:09:48,000 --> 00:09:51,000
Alright, well I'll investigate the CSI method.

160
00:09:51,000 --> 00:09:54,000
Well I guess that leaves me with the iron and graphite.

161
00:09:54,000 --> 00:09:58,000
But watch out, because I'm going to blow you away with my bling.

162
00:09:58,000 --> 00:09:59,000
Oh yeah?

163
00:09:59,000 --> 00:10:01,000
I guess the proof.

164
00:10:01,000 --> 00:10:03,000
Is in the pudding.

165
00:10:03,000 --> 00:10:09,000
Tories come over all CSI, which is apt, given that this myth will have murder,

166
00:10:09,000 --> 00:10:10,000
Dead,

167
00:10:10,000 --> 00:10:11,000
BANG!

168
00:10:11,000 --> 00:10:13,000
Double dealing,

169
00:10:13,000 --> 00:10:15,000
plenty of shots,

170
00:10:15,000 --> 00:10:19,000
and the mother of all climaxes.

171
00:10:22,000 --> 00:10:26,000
Coming up on Mythbusters, just how slippery are banana peels?

172
00:10:26,000 --> 00:10:29,000
We're about to perform the definitive test to find out.

173
00:10:29,000 --> 00:10:33,000
And later, the biggest blast in Mythbusters history.

174
00:10:48,000 --> 00:10:51,000
CSI Miami makes it look so easy.

175
00:10:51,000 --> 00:10:56,000
According to the crime lab, all you need is pure graphite, a ceramic box,

176
00:10:56,000 --> 00:11:00,000
some mysterious chemicals, and a pressure cooker.

177
00:11:00,000 --> 00:11:04,000
Then, after three days, hey presto.

178
00:11:04,000 --> 00:11:05,000
That is this technique.

179
00:11:05,000 --> 00:11:08,000
Just like nature, only a million times faster.

180
00:11:09,000 --> 00:11:13,000
Or is it like science, only a million times fabricated?

181
00:11:14,000 --> 00:11:19,000
For an expert opinion, Torey heads to UC Berkeley to see Dr. Michael Franklok.

182
00:11:19,000 --> 00:11:22,000
So if I was going to do this, what kind of chemicals do you think I should use?

183
00:11:22,000 --> 00:11:27,000
Metals like nickel, cobalt, and iron, so I would advise you to start from one of those,

184
00:11:27,000 --> 00:11:29,000
and it should be a salt in its active form.

185
00:11:29,000 --> 00:11:34,000
You still need to add some initial seeds, initial, some small diamonds.

186
00:11:34,000 --> 00:11:36,000
So you need a little piece of diamond to start the diamond?

187
00:11:36,000 --> 00:11:43,000
If you already start with a little seed, even of poor quality, it can grow and get bigger.

188
00:11:43,000 --> 00:11:47,000
Dr. Franklok's advice has given Torey the competitive edge.

189
00:11:47,000 --> 00:11:50,000
And while he's off to gather his CSI supplies...

190
00:11:50,000 --> 00:11:52,000
That is the pressure pot.

191
00:11:52,000 --> 00:11:57,000
Carrie weighs in with a recipe that puts the nuts into the peanut butter.

192
00:11:57,000 --> 00:12:00,000
To turn ordinary peanut butter into diamonds.

193
00:12:00,000 --> 00:12:03,000
There's a very simple recipe all over the internet.

194
00:12:03,000 --> 00:12:08,000
You take two charcoal briquettes, you cover them with four ounces of peanut butter,

195
00:12:08,000 --> 00:12:14,000
put them in a microwave safe dish, and then you microwave them for 60 minutes in 10-minute increments.

196
00:12:15,000 --> 00:12:19,000
Sounds crazy, but according to these internet hipsters...

197
00:12:19,000 --> 00:12:22,000
You want to take about four ounces of peanut butter.

198
00:12:22,000 --> 00:12:27,000
All that stands between you and millions of dollars is a microwave.

199
00:12:27,000 --> 00:12:34,000
Still, unsurprisingly, after just five minutes on high, things go up in smoke.

200
00:12:34,000 --> 00:12:38,000
Looks like I'll be getting some more glassware and trying this again.

201
00:12:38,000 --> 00:12:40,000
Is that what my diamonds?

202
00:12:40,000 --> 00:12:42,000
Yes.

203
00:12:43,000 --> 00:12:48,000
Eventually, three attempts, three dishes, and two microwaves later,

204
00:12:48,000 --> 00:12:51,000
Carrie has her alleged diamonds in the rough.

205
00:12:51,000 --> 00:12:56,000
I don't think I see any diamonds yet, but we have one more process to go.

206
00:12:56,000 --> 00:13:01,000
And that process is to burn off the excess carbon.

207
00:13:01,000 --> 00:13:03,000
They say diamonds are forever.

208
00:13:03,000 --> 00:13:06,000
I mean, they take forever to create.

209
00:13:06,000 --> 00:13:10,000
Well, patience is a virtue, but does it pay?

210
00:13:10,000 --> 00:13:15,000
Maybe the diamonds are microscopic, but they're supposed to be the size of fennel seeds.

211
00:13:15,000 --> 00:13:19,000
I'm not seeing them so far. I am seeing a lot of burnt peanut butter.

212
00:13:19,000 --> 00:13:22,000
Still, Carrie's not out of the contest yet.

213
00:13:22,000 --> 00:13:27,000
She can't tell the diamonds from the dirt, but maybe an expert can.

214
00:13:27,000 --> 00:13:32,000
Everyone knows monkeys go ape for bananas.

215
00:13:32,000 --> 00:13:36,000
They're a delicious treat for primates and people alike.

216
00:13:36,000 --> 00:13:41,000
But in slapstick comedy, the banana serves a more sinister purpose.

217
00:13:41,000 --> 00:13:48,000
But while you can lead a Heinemann to a banana skin, you can't make him fall.

218
00:13:48,000 --> 00:13:53,000
So now the boys are upping the ante on this banana skin.

219
00:13:53,000 --> 00:13:56,000
We expect that we're going to be falling down a lot.

220
00:13:56,000 --> 00:14:00,000
So with that in mind, we're building a special floor so we don't hurt ourselves.

221
00:14:00,000 --> 00:14:02,000
This is what it's made of.

222
00:14:02,000 --> 00:14:07,000
These springy tires are layer one of our sprung floor.

223
00:14:07,000 --> 00:14:11,000
All this wood right here is layer two.

224
00:14:11,000 --> 00:14:16,000
And this, Linolium here, this is layer three.

225
00:14:16,000 --> 00:14:19,000
The boys have busted the banana.

226
00:14:19,000 --> 00:14:24,000
And now they have the perfect venue for busting their butt.

227
00:14:24,000 --> 00:14:29,000
This may look like a completed sprung floor, but in fact it's missing one element,

228
00:14:29,000 --> 00:14:31,000
which is banana peels.

229
00:14:31,000 --> 00:14:34,000
Hundreds and hundreds and hundreds of banana peels.

230
00:14:34,000 --> 00:14:38,000
We're going to lay them out here like an obstacle course of comedy death,

231
00:14:38,000 --> 00:14:41,000
and then we're going to run a little like this.

232
00:14:41,000 --> 00:14:43,000
Go!

233
00:14:43,000 --> 00:14:49,000
That's right, they're throwing this banana peel myth one last lifeline with the ultimate test.

234
00:14:49,000 --> 00:14:51,000
Well, we've got a truckload full of bananas.

235
00:14:51,000 --> 00:14:53,000
We have our rink set up.

236
00:14:53,000 --> 00:14:56,000
The only thing now is that we need to peel all these bananas,

237
00:14:56,000 --> 00:15:01,000
so we either need a whole lot of monkeys or some volunteers.

238
00:15:01,000 --> 00:15:06,000
Well, the monkeys had a prior engagement, so the guys settled for the volunteers.

239
00:15:06,000 --> 00:15:08,000
I'm going to place them here.

240
00:15:08,000 --> 00:15:12,000
The monkeys had a prior engagement, so the guys settled for the volunteers.

241
00:15:12,000 --> 00:15:17,000
I'm going to place eight of these cones on the rink, each one with a raw egg on top.

242
00:15:17,000 --> 00:15:20,000
Our task will be to gather up all eight raw eggs,

243
00:15:20,000 --> 00:15:24,000
running back and forth, back and forth, back and forth as fast as we can without...

244
00:15:24,000 --> 00:15:27,000
I can't break this egg!

245
00:15:27,000 --> 00:15:32,000
And when we're all done, we ring the bell and that stops the timer.

246
00:15:32,000 --> 00:15:37,000
With the rink now full, Jamie's Keester is well padded,

247
00:15:37,000 --> 00:15:43,000
as this test should give the peels the best chance to redeem their slapstick reputation.

248
00:15:43,000 --> 00:15:47,000
But if he doesn't fall on his butt, then this myth is busted.

249
00:15:47,000 --> 00:15:51,000
Okay, banana peel speed test. Are you ready?

250
00:15:55,000 --> 00:15:57,000
Oh, ho, ho, ho! Five seconds!

251
00:15:59,000 --> 00:16:00,000
Ten seconds!

252
00:16:03,000 --> 00:16:04,000
Fifteen seconds!

253
00:16:04,000 --> 00:16:06,000
He's not falling down!

254
00:16:06,000 --> 00:16:11,000
He's done it again. Jamie's gravity-defying powers are spooky.

255
00:16:15,000 --> 00:16:18,000
Forty seconds! Nicely done!

256
00:16:20,000 --> 00:16:23,000
Of course, this test isn't about Admini racing.

257
00:16:23,000 --> 00:16:26,000
It's about how slippery banana peels are.

258
00:16:26,000 --> 00:16:33,000
And they are. I had to be really, really careful not slide, and even then, I slid quite a bit.

259
00:16:34,000 --> 00:16:42,000
But that caution invalidated Jamie's test, because according to the laws of comedy, he shouldn't be expecting to fall.

260
00:16:42,000 --> 00:16:46,000
So for a repeat performance, he takes off the brakes.

261
00:16:46,000 --> 00:16:48,000
Okay, Jamie on turbo.

262
00:16:52,000 --> 00:16:56,000
At long last, the banana peels take their revenge.

263
00:16:57,000 --> 00:17:00,000
And although he valiantly attempts to recover...

264
00:17:01,000 --> 00:17:04,000
Go, go, go! Twenty-nine seconds! You can still beat your time!

265
00:17:09,000 --> 00:17:12,000
He just can't overcome the giggles.

266
00:17:12,000 --> 00:17:14,000
I've never seen him like that.

267
00:17:15,000 --> 00:17:19,000
And with no complete data, it's all down to Adam.

268
00:17:19,000 --> 00:17:25,000
Okay, this is Adam's banana peel speed test in three, two, one.

269
00:17:25,000 --> 00:17:26,000
And the results...

270
00:17:28,000 --> 00:17:29,000
Speak for themselves.

271
00:17:30,000 --> 00:17:31,000
Oh!

272
00:17:39,000 --> 00:17:40,000
Hurry up!

273
00:17:42,000 --> 00:17:44,000
Fifty-two point two seconds.

274
00:17:44,000 --> 00:17:46,000
That was so much fun!

275
00:17:47,000 --> 00:17:50,000
That six falls in less than a minute.

276
00:17:50,000 --> 00:17:55,000
Which means that this myth is back in plausible territory.

277
00:17:55,000 --> 00:18:00,000
The real question is, how do they compare against the ultimate slipperiness?

278
00:18:00,000 --> 00:18:03,000
And that's pretty much what the next test is all about.

279
00:18:03,000 --> 00:18:08,000
After the break, Tori's diamond recipe takes a shocking turn.

280
00:18:08,000 --> 00:18:12,000
And the banana peel flip hits the skips.

281
00:18:12,000 --> 00:18:15,000
Planet Earth is a violent place.

282
00:18:15,000 --> 00:18:18,000
And deep below ground, it gets worse.

283
00:18:18,000 --> 00:18:24,000
Here, immense heat and pressure transform carbon into a girl's best friend.

284
00:18:24,000 --> 00:18:28,000
But perhaps that's not the only way to make diamonds.

285
00:18:28,000 --> 00:18:32,000
Well, the Mythbusters are competing to find out.

286
00:18:32,000 --> 00:18:36,000
But the truth is, the truth is that the planet Earth is a violent place.

287
00:18:36,000 --> 00:18:39,000
And deep below ground, it gets worse.

288
00:18:39,000 --> 00:18:42,000
Well, the Mythbusters are competing to find out.

289
00:18:42,000 --> 00:18:45,000
Carrie's chances appear slim.

290
00:18:45,000 --> 00:18:46,000
I don't think I see any diamonds yet.

291
00:18:46,000 --> 00:18:48,000
But Tori's done his research.

292
00:18:48,000 --> 00:18:53,000
And he now has a solid lead on that annoyingly vague CSI recipe.

293
00:18:53,000 --> 00:18:57,000
Now, I have everything I need to start making diamonds.

294
00:18:57,000 --> 00:18:59,000
First, I have my pressure cooker.

295
00:18:59,000 --> 00:19:00,000
I have my ingredients.

296
00:19:00,000 --> 00:19:02,000
I have my hunk of graphite.

297
00:19:02,000 --> 00:19:05,000
The chemical that I'm going to use is ferric nitrate.

298
00:19:05,000 --> 00:19:13,000
What I'm going to do is stick this and that in this, put it in that.

299
00:19:13,000 --> 00:19:16,000
And that's as specific as it gets.

300
00:19:16,000 --> 00:19:20,000
But let's not forget the most important ingredient, a diamond seed.

301
00:19:20,000 --> 00:19:24,000
Without it, this recipe has no chance of working.

302
00:19:24,000 --> 00:19:28,000
For safety, Tori rigs a stun gun.

303
00:19:28,000 --> 00:19:30,000
Yeah, it's been a while since we used one of these.

304
00:19:30,000 --> 00:19:32,000
And I kind of forget what it feels like.

305
00:19:32,000 --> 00:19:37,000
And lights the gas from outside the bunker.

306
00:19:37,000 --> 00:19:39,000
I'll leave it there for three days.

307
00:19:39,000 --> 00:19:43,000
And then at the end of that, check and see if I've made any diamonds.

308
00:19:43,000 --> 00:19:49,000
And while Tori waits, grants off to the blacksmith for his shot at diamonds.

309
00:19:49,000 --> 00:19:53,000
So to execute this diamond recipe, we need to melt iron.

310
00:19:53,000 --> 00:19:55,000
And to do that, you need a foundry.

311
00:19:55,000 --> 00:19:57,000
We don't have a foundry at Mythbusters,

312
00:19:57,000 --> 00:20:01,000
but we've come to a place that does have a foundry, the Crucible.

313
00:20:01,000 --> 00:20:07,000
Supposedly, this recipe replicates the heat and pressure that make natural diamonds.

314
00:20:07,000 --> 00:20:12,000
All you need to do is melt graphite into molten iron and quench the mixture.

315
00:20:12,000 --> 00:20:19,000
Then just dissolve the iron in acid and voila, your very own sparkling gemstones.

316
00:20:19,000 --> 00:20:25,000
So to get this recipe fired up, Grant enlists master smelter Nick DiFilippo.

317
00:20:25,000 --> 00:20:26,000
All right.

318
00:20:26,000 --> 00:20:29,000
So let's dig up.

319
00:20:29,000 --> 00:20:35,000
The graphite and iron go into the furnace to be heated to 2,500 degrees.

320
00:20:35,000 --> 00:20:47,000
Make me diamonds!

321
00:20:47,000 --> 00:20:54,000
And at that heat, Grant's stretching the rules of the homemade diamonds contest just a touch.

322
00:20:54,000 --> 00:20:58,000
But after 20 minutes, it's the moment of truth.

323
00:20:58,000 --> 00:21:00,000
So this is it. Now the pour, right?

324
00:21:00,000 --> 00:21:01,000
Yep, here we go.

325
00:21:01,000 --> 00:21:04,000
There's the iron.

326
00:21:04,000 --> 00:21:10,000
As the iron hits the water, the contraction of the metal should apparently be forming diamonds.

327
00:21:10,000 --> 00:21:15,000
And after waiting for the iron to cool, it's time to harvest the spoils.

328
00:21:15,000 --> 00:21:18,000
Rich! I'm gonna be rich!

329
00:21:18,000 --> 00:21:21,000
Finally, this gig's really paying off.

330
00:21:21,000 --> 00:21:24,000
Okay, Grant could be on to a winner.

331
00:21:24,000 --> 00:21:29,000
So, booty and toe, he heads home to iron out the details.

332
00:21:29,000 --> 00:21:35,000
The idea is that at this point, your diamonds have already been made.

333
00:21:35,000 --> 00:21:41,000
It's just that they're encased in this iron and you have to get the iron off in order to get the diamonds.

334
00:21:41,000 --> 00:21:44,000
And Grant's not just outside for the view.

335
00:21:44,000 --> 00:21:49,000
The iron stripper is super concentrated hydrochloric acid.

336
00:21:49,000 --> 00:21:52,000
But first impressions are a little disappointing.

337
00:21:52,000 --> 00:21:56,000
There's bubbles aplenty, but not a glimmer of glitz.

338
00:21:56,000 --> 00:22:04,000
Right now, it looks like a roiling soup of butternut squash, but not quite that appetizing.

339
00:22:04,000 --> 00:22:06,000
There's gotta be a fortune in there somewhere.

340
00:22:06,000 --> 00:22:10,000
Well, Grant, anything's possible.

341
00:22:10,000 --> 00:22:20,000
So, I've let my iron dissolve overnight in the acid, and now it's time to harvest my diamonds.

342
00:22:20,000 --> 00:22:25,000
Grant neutralizes the acid, but the results are low on sparkle.

343
00:22:25,000 --> 00:22:33,000
I think what we're gonna have to do is take this somewhere where they can see if there's a diamond hidden somewhere in the rough.

344
00:22:33,000 --> 00:22:36,000
If they're in there, they're hidden well.

345
00:22:41,000 --> 00:22:46,000
The Mythbusters are tackling the slapstick favorite slipping on a banana peel.

346
00:22:46,000 --> 00:22:49,000
Thirty-seven! Come on!

347
00:22:49,000 --> 00:22:55,000
And while the skins certainly are slippery, the fun ain't over yet.

348
00:22:55,000 --> 00:23:00,000
We wanted to compare the slipperiness of bananas to something that was ultimately slippery.

349
00:23:00,000 --> 00:23:05,000
And we went looking and we found this lubricant it's used to help animals give birth.

350
00:23:05,000 --> 00:23:09,000
We're gonna spread it out on this field and hilarity will ensue.

351
00:23:09,000 --> 00:23:17,000
By comparing the peels to the ultra-slick lube, the guys can find out just how slippery a banana peel really is.

352
00:23:17,000 --> 00:23:20,000
Okay, commencing the slime.

353
00:23:21,000 --> 00:23:25,000
After a quick squirt, the rink is ready for testing.

354
00:23:25,000 --> 00:23:28,000
And by now, well, you know the drill.

355
00:23:28,000 --> 00:23:31,000
Super-duper lube, starting.

356
00:23:36,000 --> 00:23:41,000
And it's a hop, a skid, and a thud, till the lube takes Jamie out.

357
00:23:43,000 --> 00:23:46,000
Come on, get up, get up, get up! Thirty-seven seconds!

358
00:23:47,000 --> 00:23:50,000
Whoa!

359
00:23:56,000 --> 00:24:03,000
That's only two falls for Jamie, but since he didn't finish bananas, it's down to Adam for the final test.

360
00:24:03,000 --> 00:24:05,000
Be careful, old buddy.

361
00:24:05,000 --> 00:24:08,000
Okay, in three, two, one.

362
00:24:09,000 --> 00:24:12,000
Whoa! Jesus, bro!

363
00:24:12,000 --> 00:24:15,000
It's like ice skating!

364
00:24:16,000 --> 00:24:19,000
I am almost no control.

365
00:24:19,000 --> 00:24:21,000
Twenty-two seconds.

366
00:24:21,000 --> 00:24:26,000
That's fall number one, and I think the tally should take it from here.

367
00:24:40,000 --> 00:24:41,000
What was my time?

368
00:24:41,000 --> 00:24:43,000
One minute, twenty seconds.

369
00:24:43,000 --> 00:24:47,000
That was no faking, man. It gets worse the farther you go.

370
00:24:48,000 --> 00:24:56,000
Clearly, with two more tumbles and an extra thirty seconds on the clock, falling down with the lube was practically compulsory.

371
00:24:56,000 --> 00:25:00,000
If I had to give it a rating, I'd call our birthing agent a nine.

372
00:25:00,000 --> 00:25:05,000
I could conceive of something more slippery, like a field of roller skates.

373
00:25:05,000 --> 00:25:09,000
But within that, I'd say that bananas were easily a six.

374
00:25:09,000 --> 00:25:11,000
So, how do you want to call this one?

375
00:25:11,000 --> 00:25:13,000
What exactly was the myth we started out with?

376
00:25:13,000 --> 00:25:19,000
Okay, according to the laws of comedy, the myth is that one banana peel plus one person equals one person on their butt.

377
00:25:19,000 --> 00:25:25,000
Well, then we'd have to call it busted, because a banana peel was definitely not a guarantee that you were going to fall.

378
00:25:25,000 --> 00:25:31,000
But I do have to say that with their leathery top and that permanently lubricated underside, they're perfect for slipping on.

379
00:25:31,000 --> 00:25:33,000
I'd say this is busted, but only just.

380
00:25:33,000 --> 00:25:34,000
Agreed.

381
00:25:34,000 --> 00:25:39,000
Next up, the boys dip into a Seinfeld classic.

382
00:25:39,000 --> 00:25:40,000
And...

383
00:25:40,000 --> 00:25:47,000
The biggest boom in the history of Mythbusters.

384
00:25:47,000 --> 00:25:53,000
It may not look like it, but we're professionals. Do us a favor.

385
00:25:53,000 --> 00:25:55,000
Don't try this at home! Whoa!

386
00:25:55,000 --> 00:26:02,000
The banana peel flip may be busted, but the guys are taking a bite out of something else.

387
00:26:02,000 --> 00:26:03,000
I've got a good one.

388
00:26:03,000 --> 00:26:04,000
Yeah? What's that?

389
00:26:04,000 --> 00:26:05,000
Double dipping.

390
00:26:05,000 --> 00:26:11,000
Oh, that you can't dip, bite, and dipping a second time like in Seinfeld.

391
00:26:11,000 --> 00:26:16,000
Exactly. The myth was that one person was going to fall.

392
00:26:16,000 --> 00:26:19,000
And then the other person was going to be like,

393
00:26:19,000 --> 00:26:24,000
that you can't dip, bite, and dipping a second time like in Seinfeld.

394
00:26:24,000 --> 00:26:28,000
Exactly. The myth's been around for a lot longer than that, but Seinfeld popularized it.

395
00:26:28,000 --> 00:26:31,000
If I remember correctly, when George is accused of double dipping,

396
00:26:31,000 --> 00:26:38,000
the guy tells him that dipping, biting, and dipping again is akin to putting his whole mouth in the bowl of dip.

397
00:26:38,000 --> 00:26:43,000
It's a classic Seinfeld moment that the fans have begged us to test.

398
00:26:43,000 --> 00:26:48,000
An unwitting George finds himself breaking dip dunking etiquette.

399
00:26:48,000 --> 00:26:53,000
What? Did you just double dip that chip?

400
00:26:53,000 --> 00:26:55,000
You double dipped the chip?

401
00:26:55,000 --> 00:26:58,000
By dipping the chip twice, supposedly...

402
00:26:58,000 --> 00:27:01,000
That's like putting your whole mouth right in the dip.

403
00:27:01,000 --> 00:27:06,000
...is this bacterial baloney, or is there something to this Seinfeld saga?

404
00:27:06,000 --> 00:27:08,000
Just take one dip and end it.

405
00:27:09,000 --> 00:27:16,000
The theory is that double dipping transfers microbes from your mouth into the dip and then onto other people.

406
00:27:16,000 --> 00:27:22,000
But can the germs inside your mouth really hit your ride on your chip of choice?

407
00:27:22,000 --> 00:27:24,000
What's your plan on this one?

408
00:27:24,000 --> 00:27:29,000
We've got some chips, we've got some dip, and I think it's time to bring back our old friends, the Petri dishes.

409
00:27:29,000 --> 00:27:34,000
So we'll do a control, we'll do double dipping, and then we've got to put our old mouths in the bowl.

410
00:27:34,000 --> 00:27:36,000
We'll get separate bowls.

411
00:27:36,000 --> 00:27:37,000
You want separate bowls?

412
00:27:37,000 --> 00:27:38,000
Yeah.

413
00:27:38,000 --> 00:27:39,000
Okay.

414
00:27:39,000 --> 00:27:45,000
Separate bowls it is, and with a bunch of soy agar Petri dishes primed for bacterial growth,

415
00:27:45,000 --> 00:27:48,000
it's time to double dip for science.

416
00:27:48,000 --> 00:27:52,000
We've got two kinds of dip, a cream based dip, a salsa based dip, and a bowl full of chips.

417
00:27:52,000 --> 00:27:54,000
Let me tell you how we're going to do this experiment.

418
00:27:54,000 --> 00:28:01,000
First, before we touch anything, we're going to stick a swab in each of these kinds of dips and put them on an agar plate and try and culture them.

419
00:28:01,000 --> 00:28:03,000
That's our control.

420
00:28:03,000 --> 00:28:05,000
Then we're going to double dip in these dips.

421
00:28:05,000 --> 00:28:07,000
We're going to dip, bite, dip again.

422
00:28:07,000 --> 00:28:12,000
Once we've done that, we're going to culture them again and see if we've added any bacteria.

423
00:28:13,000 --> 00:28:19,000
But the story includes a third wrinkle in which the guy says the double dipping is like putting your whole mouth into the bowl.

424
00:28:19,000 --> 00:28:20,000
So we're going to do that.

425
00:28:20,000 --> 00:28:23,000
We're going to take as much of the dip in our mouths as possible.

426
00:28:23,000 --> 00:28:24,000
It's going to be really gross.

427
00:28:24,000 --> 00:28:30,000
We're going to spin it back out and we're going to culture it one last time and see if that's equivalent to double dipping.

428
00:28:30,000 --> 00:28:32,000
And it really is that simple.

429
00:28:32,000 --> 00:28:37,000
With each MythBusters swabbing three experiments, they're ready to incubate.

430
00:28:38,000 --> 00:28:39,000
Perfect.

431
00:28:39,000 --> 00:28:41,000
It's right around 98 degrees.

432
00:28:41,000 --> 00:28:44,000
So we want it right about the same as the human body, huh?

433
00:28:44,000 --> 00:28:46,000
Yeah, for roughly a day.

434
00:28:46,000 --> 00:28:47,000
We'll come back tomorrow and check it out.

435
00:28:47,000 --> 00:28:48,000
Okay.

436
00:28:48,000 --> 00:28:54,000
And thanks to the wonders of editing, time's up for the breeding bacteria.

437
00:28:54,000 --> 00:28:58,000
The biohazards are ready for their close-up, but there's a problem.

438
00:29:00,000 --> 00:29:04,000
That's the control and there's already bacteria in the salsa.

439
00:29:05,000 --> 00:29:10,000
They check all the salsa-only controls and everyone tells the same story.

440
00:29:11,000 --> 00:29:16,000
Even with no human saliva, the dips are already brimming with bugs.

441
00:29:17,000 --> 00:29:21,000
Clearly, we are going to need to do this test again and remove some variables.

442
00:29:22,000 --> 00:29:28,000
Yep, with the control showing more bacterial growth than Adam's feet, the boys are going to need a plan B.

443
00:29:31,000 --> 00:29:35,000
I really liked that bit where we took that thing and we put the thing on it and did that thing to it.

444
00:29:35,000 --> 00:29:37,000
Yeah, didn't make it into the show.

445
00:29:37,000 --> 00:29:38,000
What?

446
00:29:38,000 --> 00:29:39,000
Yeah, sorry.

447
00:29:39,000 --> 00:29:45,000
But they put it on the web, so fans who want to see it can log on to thediscovery.com slash mythbusters to check it out.

448
00:29:49,000 --> 00:29:53,000
The mythbusters are battling it out, making homegrown diamonds.

449
00:29:53,000 --> 00:29:57,000
And so far, their crusade is a little short on bling.

450
00:29:57,000 --> 00:30:00,000
There's got to be a fortune in there somewhere.

451
00:30:00,000 --> 00:30:03,000
But Tori's not finished yet.

452
00:30:04,000 --> 00:30:13,000
His CSI recipe was simple, just graphite and chemicals inside a pressure cooker and in three days, you'll have a rock.

453
00:30:13,000 --> 00:30:16,000
So, was it a recipe for success?

454
00:30:16,000 --> 00:30:21,000
Alright, so it's been three days and now it's time to check my diamonds.

455
00:30:21,000 --> 00:30:27,000
The real question is, what am I going to do with all my money once I start my diamond company?

456
00:30:27,000 --> 00:30:30,000
I wouldn't count your diamonds just yet, Tori.

457
00:30:31,000 --> 00:30:33,000
Oh my gosh.

458
00:30:33,000 --> 00:30:36,000
The graphite has not turned to a diamond.

459
00:30:36,000 --> 00:30:42,000
Looks like my diamond business is not going so well.

460
00:30:42,000 --> 00:30:45,000
Which means there's no clear homegrown winner.

461
00:30:45,000 --> 00:30:54,000
So for an expert adjudication, the team heads to UC Berkeley to see Dr. Kent Ross at his electron microscope.

462
00:30:54,000 --> 00:30:57,000
First up is Grant's iron and graphite.

463
00:30:57,000 --> 00:31:05,000
Nothing that I'm seeing now has a shape that says this has to be a diamond.

464
00:31:05,000 --> 00:31:07,000
Grant's out of contention.

465
00:31:07,000 --> 00:31:10,000
So next is Carrie's peanut butter dirt.

466
00:31:10,000 --> 00:31:12,000
Chirkel. You've got chirkel.

467
00:31:12,000 --> 00:31:16,000
Which leaves only Tori and his diamond seed.

468
00:31:16,000 --> 00:31:19,000
The straight edges from the cut faces are still perfectly smooth.

469
00:31:19,000 --> 00:31:23,000
It's just like it was when you started your experiment.

470
00:31:24,000 --> 00:31:27,000
There's been no growth whatsoever.

471
00:31:27,000 --> 00:31:31,000
And that's game over. No diamonds, nobody wins.

472
00:31:31,000 --> 00:31:33,000
But where does that leave the myth?

473
00:31:33,000 --> 00:31:36,000
So we all tried making diamonds and we all failed miserably.

474
00:31:36,000 --> 00:31:40,000
Yeah, I think it's safe to say that all these recipes are busted.

475
00:31:40,000 --> 00:31:41,000
Totally busted.

476
00:31:41,000 --> 00:31:48,000
But you know what? Our researchers have come up with someone who can make diamonds in a myth buster way.

477
00:31:48,000 --> 00:31:49,000
Cool.

478
00:31:49,000 --> 00:31:50,000
You guys remember Van Romero?

479
00:31:50,000 --> 00:31:51,000
From New Mexico Tech.

480
00:31:51,000 --> 00:31:56,000
He says he can make synthetic diamonds and he wants to show us how.

481
00:31:56,000 --> 00:31:58,000
Awesome. What are we waiting for?

482
00:31:58,000 --> 00:32:08,000
So for a proper chance at making some bona fide bling, the myth busters head to New Mexico Institute of Mining and Technology to meet Dr. Van Romero.

483
00:32:08,000 --> 00:32:10,000
So Van, we heard that you know how to make diamonds.

484
00:32:10,000 --> 00:32:11,000
You've come to the right place.

485
00:32:11,000 --> 00:32:15,000
Here at New Mexico Tech we do applied research and we do industrial research.

486
00:32:15,000 --> 00:32:17,000
And part of that industrial research is actually making diamonds.

487
00:32:17,000 --> 00:32:20,000
All right, well cut to the chase. Tell us how to do it.

488
00:32:20,000 --> 00:32:23,000
You know what? Instead of telling you how, let's show you how to do it.

489
00:32:23,000 --> 00:32:24,000
Even better.

490
00:32:24,000 --> 00:32:25,000
Let's go do it.

491
00:32:28,000 --> 00:32:33,000
Step one, a Van's mysterious method involves driving into the middle of nowhere.

492
00:32:34,000 --> 00:32:38,000
Step two involves arriving at an almighty bunker.

493
00:32:38,000 --> 00:32:42,000
And as for step three, well, Tori's one step ahead.

494
00:32:43,000 --> 00:32:49,000
Considering that we're standing outside of a bunker, my feeling is it probably involves explosives, which is never a bad thing.

495
00:32:51,000 --> 00:32:52,000
Tori's got it in one.

496
00:32:54,000 --> 00:32:57,000
Van the man reckons he can make bling with a boom.

497
00:32:58,000 --> 00:33:03,000
And not just any boom, but the biggest boom in myth busters history.

498
00:33:04,000 --> 00:33:06,000
In Black Powder Shark.

499
00:33:08,000 --> 00:33:12,000
400 pounds of explosives turned Hugo into Hugo.

500
00:33:13,000 --> 00:33:15,000
In 22,000 foot fall.

501
00:33:16,000 --> 00:33:19,000
500 pounds made a train station turn torpedo.

502
00:33:20,000 --> 00:33:22,000
And in cement mix up.

503
00:33:23,000 --> 00:33:26,000
800 pounds made a truck take flight.

504
00:33:27,000 --> 00:33:30,000
But all will be eclipsed right here, right now.

505
00:33:31,000 --> 00:33:42,000
Because at ground zero, 500 yards from the bunker, Van's team are packing a 20 foot high wooden tube with 5,000 pounds of high explosives.

506
00:33:43,000 --> 00:33:46,000
But can a bang this big really create diamonds?

507
00:33:47,000 --> 00:33:48,000
Okay, you guys ready to make some diamonds?

508
00:33:48,000 --> 00:33:49,000
Yeah.

509
00:33:50,000 --> 00:33:51,000
Strap yourself in.

510
00:33:52,000 --> 00:33:54,000
This one's going to be gigantic.

511
00:33:55,000 --> 00:34:00,000
Charging five, four, three, two, one, zero.

512
00:34:14,000 --> 00:34:18,000
With over 10 times the might of any other myth busters boom.

513
00:34:21,000 --> 00:34:23,000
It sure was a blast.

514
00:34:24,000 --> 00:34:27,000
But did it germinate any gemstones?

515
00:34:28,000 --> 00:34:29,000
Up next.

516
00:34:30,000 --> 00:34:33,000
Almost worse watching you do it than doing it myself.

517
00:34:34,000 --> 00:34:37,000
Adam and Jamie crack the double dipping dilemma.

518
00:34:37,000 --> 00:34:52,000
The myth busters are getting all bacteriological as they probe a Seinfeld double dipping dilemma.

519
00:34:53,000 --> 00:34:57,000
But thanks to masses of microbes, their first test was ruined.

520
00:34:58,000 --> 00:35:00,000
So this time the boys are taking precautions.

521
00:35:01,000 --> 00:35:06,000
We need to do what we normally do, which is start eliminating variables and then get back in there and do the test.

522
00:35:07,000 --> 00:35:11,000
Stereo-salsa, sterile chips, clean space, rubber gloves, surgical masks.

523
00:35:12,000 --> 00:35:14,000
The only variable being our saliva.

524
00:35:15,000 --> 00:35:16,000
Perfect. Let's do it.

525
00:35:17,000 --> 00:35:23,000
So Adam starts with the chip sterilization, adding to New Tech Corporation to have them irradiated.

526
00:35:25,000 --> 00:35:27,000
Will these be safe to eat after that?

527
00:35:28,000 --> 00:35:30,000
They might taste a little funny, but they'll be totally safe to eat.

528
00:35:31,000 --> 00:35:32,000
Okay, great.

529
00:35:33,000 --> 00:35:35,000
Funny tasting and more importantly, sterile.

530
00:35:35,000 --> 00:35:44,000
Friends and family of bacteria may want to look away now because 2.5 million rads of radiation is about to be unleashed.

531
00:35:45,000 --> 00:35:47,000
That is so much cooler than I thought it would be.

532
00:35:48,000 --> 00:35:53,000
I mean, it's like see this beam coming down like an anvil crossing bacteria in its wake.

533
00:35:54,000 --> 00:35:56,000
Electrons scattering little bacteriological lives to the winds.

534
00:35:57,000 --> 00:36:02,000
Uncharacteristically, Adam is enjoying this far too much and soon enough...

535
00:36:02,000 --> 00:36:05,000
There you have it, one set of totally sterile chips.

536
00:36:06,000 --> 00:36:11,000
Meanwhile, back at the shop, Jamie's also getting sterile for science.

537
00:36:12,000 --> 00:36:18,000
He first builds a clean room for the test and then conjures up some decontaminated dip.

538
00:36:19,000 --> 00:36:23,000
Two parts agar, one part sterilized water and voila.

539
00:36:24,000 --> 00:36:30,000
Well, okay then. I think that kind of looks like as close to salsa as we're going to get.

540
00:36:30,000 --> 00:36:36,000
To make sure the test runs smoothly, the boys have Dr. Russell Vance, an expert in pathogenesis.

541
00:36:37,000 --> 00:36:38,000
He's the guy in the middle.

542
00:36:39,000 --> 00:36:40,000
What's first?

543
00:36:41,000 --> 00:36:43,000
That'd be the salsa only control.

544
00:36:44,000 --> 00:36:51,000
Using much more sophisticated equipment than those earlier swabs, Dr. Vance prepares the Petri dishes.

545
00:36:52,000 --> 00:36:53,000
What now?

546
00:36:53,000 --> 00:36:57,000
Now is double dipping, except this time with the fully irradiated chips.

547
00:36:58,000 --> 00:36:59,000
Okay, here we go.

548
00:37:01,000 --> 00:37:13,000
Once the infamous double dip has been double dipped, the salsa is sampled and plated up, leaving just the full mouth test.

549
00:37:14,000 --> 00:37:15,000
Alright, now for the really gross one.

550
00:37:19,000 --> 00:37:23,000
And once again, it's delightful to watch.

551
00:37:24,000 --> 00:37:29,000
It's almost worse than what you do it for yourself.

552
00:37:30,000 --> 00:37:31,000
That's experiment over.

553
00:37:32,000 --> 00:37:38,000
Dr. Vance plates the full mouth test and they join the double dip and control plates in the incubator.

554
00:37:39,000 --> 00:37:40,000
Okay, they're in the incubator.

555
00:37:41,000 --> 00:37:42,000
Thanks, Dr. Vance.

556
00:37:43,000 --> 00:37:45,000
Now we wait, but not for long.

557
00:37:46,000 --> 00:37:49,000
So for viewers playing at home, here's what to look for.

558
00:37:50,000 --> 00:37:59,000
The stated myth is that double dipping is just as bad as putting your whole mouth in the bowl of dip in terms of transmitting bacteria to it.

559
00:38:00,000 --> 00:38:07,000
So if this is true, we would expect to see the same amount of bacteria on the double dipping Petri dish as we would on the whole mouth in the bowl Petri dish.

560
00:38:08,000 --> 00:38:09,000
Here we go.

561
00:38:10,000 --> 00:38:12,000
This is my control.

562
00:38:13,000 --> 00:38:14,000
It's clean.

563
00:38:15,000 --> 00:38:16,000
Here's your control.

564
00:38:17,000 --> 00:38:18,000
It's clean.

565
00:38:18,000 --> 00:38:19,000
What are you expecting to see?

566
00:38:20,000 --> 00:38:24,000
That's a clean start, meaning Jamie's salsa was bacteria free.

567
00:38:25,000 --> 00:38:29,000
So from here on in, any microbes can only be from their saliva.

568
00:38:30,000 --> 00:38:32,000
Here is my double dipping.

569
00:38:33,000 --> 00:38:34,000
Maybe one.

570
00:38:36,000 --> 00:38:38,000
There's one bacterial colony.

571
00:38:40,000 --> 00:38:41,000
And for Jamie.

572
00:38:42,000 --> 00:38:43,000
Maybe three or four or so.

573
00:38:44,000 --> 00:38:47,000
But how does that compare with the whole mouth results?

574
00:38:48,000 --> 00:38:49,000
Lots.

575
00:38:50,000 --> 00:38:51,000
Tons. Check out yours.

576
00:38:54,000 --> 00:38:55,000
Also lots.

577
00:38:56,000 --> 00:38:57,000
About the same.

578
00:38:58,000 --> 00:38:59,000
Well, I guess that tells the whole story, doesn't it?

579
00:39:00,000 --> 00:39:02,000
It tells the entire story that we set out to tell.

580
00:39:03,000 --> 00:39:06,000
So to all those germophobes out there, I say double dipping.

581
00:39:07,000 --> 00:39:09,000
Not such a big deal.

582
00:39:10,000 --> 00:39:13,000
Plenty more bacteria in here than you are imparting by double dipping.

583
00:39:13,000 --> 00:39:17,000
And besides, what the heck's your immune system for anyway?

584
00:39:18,000 --> 00:39:19,000
Indeed.

585
00:39:22,000 --> 00:39:25,000
Coming right up, the team bring on the bling.

586
00:39:28,000 --> 00:39:30,000
In the Big Bang finale.

587
00:39:43,000 --> 00:39:44,000
Dead.

588
00:39:45,000 --> 00:39:50,000
So they hunkered in a bunker to test the tail that you can use explosives to bring forth some bling.

589
00:39:54,000 --> 00:39:55,000
That was awesome!

590
00:40:03,000 --> 00:40:07,000
The theory is that the pressure and heat at ground zero is so intense,

591
00:40:08,000 --> 00:40:11,000
it converts carbon to diamond in an instant.

592
00:40:12,000 --> 00:40:15,000
So to delve deeper into that theory, it's back to the lab,

593
00:40:16,000 --> 00:40:20,000
so the team can prep a more manageable diamond explosion of their own.

594
00:40:21,000 --> 00:40:23,000
So this is the device that we're going to be using.

595
00:40:24,000 --> 00:40:27,000
We're going to have you guys pack the special sauce into the device here.

596
00:40:28,000 --> 00:40:30,000
This metal tube sits at the center of the blast.

597
00:40:31,000 --> 00:40:36,000
And in the center of that is a mixture of graphite, cobalt, and other chemicals.

598
00:40:36,000 --> 00:40:39,000
The cylinder is placed in the very center of a wooden barrel,

599
00:40:40,000 --> 00:40:42,000
which is then filled to the brim with anfo.

600
00:40:44,000 --> 00:40:45,000
Smells good.

601
00:40:46,000 --> 00:40:47,000
Smells like diamonds.

602
00:40:48,000 --> 00:40:52,000
Now I know they say diamonds are girls best friend, but let's face it,

603
00:40:53,000 --> 00:40:56,000
if you're making diamonds with explosives, I'm starting to warm up to them myself.

604
00:40:57,000 --> 00:41:01,000
It's a wind bling situation, so the team hunkers in the bunker once again.

605
00:41:02,000 --> 00:41:06,000
Five, four, three, two, one, zero.

606
00:41:18,000 --> 00:41:23,000
That blast may have been a wee bit smaller, but the effect should still be the same.

607
00:41:24,000 --> 00:41:25,000
Diamonds, apparently.

608
00:41:26,000 --> 00:41:30,000
That looks in much better shape than I thought it was going to look.

609
00:41:31,000 --> 00:41:33,000
That's what we wanted, right? Pressure and heat.

610
00:41:34,000 --> 00:41:39,000
Back at the shop, it's the moment of truth as the very myth gets dissected.

611
00:41:40,000 --> 00:41:44,000
Tori's so confident he's taking precautions against bling blindness.

612
00:41:45,000 --> 00:41:46,000
Everybody's happy.

613
00:41:47,000 --> 00:41:48,000
Ready to see our diamonds?

614
00:41:49,000 --> 00:41:50,000
Show me the money.

615
00:41:51,000 --> 00:41:53,000
Perfect, that's great. Excellent. Good job.

616
00:41:54,000 --> 00:41:55,000
Where's the diamond?

617
00:41:56,000 --> 00:41:57,000
Well, we got to take it through a few chemical processes first.

618
00:41:57,000 --> 00:42:03,000
They might not look like much, but after a quick chemical bath to remove the excess cobalt and graphite,

619
00:42:04,000 --> 00:42:09,000
they still don't look like much, but these are definitely diamonds.

620
00:42:10,000 --> 00:42:12,000
Gemstones know diamonds yes.

621
00:42:13,000 --> 00:42:14,000
So how much are these diamonds worth?

622
00:42:15,000 --> 00:42:16,000
About a quarter.

623
00:42:17,000 --> 00:42:18,000
A quarter of a million?

624
00:42:19,000 --> 00:42:20,000
No, 25 cents.

625
00:42:21,000 --> 00:42:22,000
Oh, that was money well spent.

626
00:42:23,000 --> 00:42:24,000
I'm going back and get diamonds the old fashioned way.

627
00:42:25,000 --> 00:42:29,000
The blast may have mimicked the pressure and heat of the Earth's core,

628
00:42:30,000 --> 00:42:37,000
but even with all that explosive energy, the end result is still only cheap and cheerful industrial diamonds.

629
00:42:38,000 --> 00:42:42,000
We made diamonds in a completely spectacular, totally impossible to do at home way,

630
00:42:43,000 --> 00:42:45,000
but still all that heat and pressure, we didn't get gemstones.

631
00:42:46,000 --> 00:42:47,000
Yeah, we made little diamonds.

632
00:42:48,000 --> 00:42:51,000
I mean the kind that you use in industry, the kinds that you put on a drill bit, or saw blade, you know, stuff like that.

633
00:42:51,000 --> 00:42:55,000
So the idea of homemade gemstones, totally and completely busted.

634
00:42:56,000 --> 00:42:59,000
And like virtually all get rich quick schemes, this one's bogus.

635
00:43:00,000 --> 00:43:02,000
Don't you guys want to see that 5,000 pound explosion again?

636
00:43:03,000 --> 00:43:04,000
Absolutely!

637
00:43:07,000 --> 00:43:10,000
While the team may not have made their fortune with diamond gems,

638
00:43:12,000 --> 00:43:15,000
they did make Mythbusters history.

639
00:43:15,000 --> 00:43:21,000
And this explosion is worth its weight in gold.
