67 00:03:30,000 --> 00:03:32,000 So where do we start? 68 00:03:32,000 --> 00:03:37,000 I think we start to find out how long it takes to make a flint arrowhead as opposed to a sharpened stick. 69 00:03:37,000 --> 00:03:38,000 Let's have a race. 70 00:03:38,000 --> 00:03:42,000 You should make some flint ones and I'll sharpen some sticks and we'll compare production times. 71 00:03:42,000 --> 00:03:49,000 Yeah, and when it comes to testing time, we need to both look at their lethality as well as their accuracy because they're both important. 72 00:03:49,000 --> 00:03:50,000 I agree. 73 00:03:50,000 --> 00:03:57,000 So if you're ready, time to dust off those flint-napping skills because if I'm right, it's about 70 years since you've done it last. 74 00:03:57,000 --> 00:03:59,000 Ha ha ha. 75 00:03:59,000 --> 00:04:00,000 And they're off. 76 00:04:00,000 --> 00:04:07,000 First up in this archaeology anecdote, Adam and Jamie go head to head in an arrow making time trial. 77 00:04:07,000 --> 00:04:09,000 Okay. 78 00:04:09,000 --> 00:04:11,000 Three and a half minutes. 79 00:04:11,000 --> 00:04:15,000 I can't even come close to competing with that. 80 00:04:15,000 --> 00:04:17,000 There's no contest. 81 00:04:17,000 --> 00:04:24,000 Jamie's been shafted, but he keeps chipping away and an hour later, finally finishes. 82 00:04:24,000 --> 00:04:27,000 We've just seen that it takes much longer to make a stone arrowhead. 83 00:04:27,000 --> 00:04:30,000 Now we need to find out if that makes for better arrows. 84 00:04:30,000 --> 00:04:34,000 And to do that, we're going to start with a simple lethality test. 85 00:04:34,000 --> 00:04:42,000 We'll make some more flint heads, we'll make some more pointed sticks, and we'll fire them into a ballistics gel dummy from a point blank range. 86 00:04:42,000 --> 00:04:48,000 To make sure that both aerotypes are fired consistently, we're going to use the automatic archer that we built for the Ninja Special. 87 00:04:48,000 --> 00:04:50,000 So that's the plan. 88 00:04:50,000 --> 00:04:54,000 But what does our resident Neanderthal think is going to happen? 89 00:04:54,000 --> 00:05:05,000 Well said. 90 00:05:05,000 --> 00:05:09,000 So with the predictions in place, it's time to get to the point. 91 00:05:09,000 --> 00:05:10,000 All right, you ready? 92 00:05:10,000 --> 00:05:11,000 Go for it. 93 00:05:11,000 --> 00:05:14,000 Here we go. In three, two, one. 94 00:05:14,000 --> 00:05:16,000 Worked like a charm. 95 00:05:16,000 --> 00:05:18,000 Totally. 96 00:05:18,000 --> 00:05:21,000 The sharp stick shot straight as an arrow. 97 00:05:21,000 --> 00:05:24,000 But what about the all important penetration? 98 00:05:24,000 --> 00:05:25,000 Wow. 99 00:05:25,000 --> 00:05:27,000 8.5 inches. 100 00:05:27,000 --> 00:05:32,000 8.5 inches ain't bad, but will the flint be flung further? 101 00:05:32,000 --> 00:05:37,000 Okay, here goes the arrowhead in three, two, one. 102 00:05:37,000 --> 00:05:39,000 Look at that. 103 00:05:39,000 --> 00:05:41,000 That is pretty clear. 104 00:05:41,000 --> 00:05:44,000 The arrowhead went a good inch farther. 105 00:05:44,000 --> 00:05:51,000 There's a glint of flint at the back of the bust and one inch more penetration confirmed by a bunch more tests. 106 00:05:51,000 --> 00:05:53,000 But Jamie spotted a problem. 107 00:05:53,000 --> 00:06:00,000 The ballistics medium by itself is good flesh analog, but animals usually have fur and hide and things like that on it. 108 00:06:00,000 --> 00:06:06,000 So we're going to run the test again and see whether we get any kind of different results with this on it. 109 00:06:06,000 --> 00:06:12,000 Despite the hide slightly hindering both the stick and flint arrows, the results are the same. 110 00:06:12,000 --> 00:06:14,000 Actually, they were very close. 111 00:06:14,000 --> 00:06:18,000 But is that enough to justify all the effort of making one? 112 00:06:18,000 --> 00:06:23,000 This one went in this far. This one went in this far. I mean, you're dead either way. 113 00:06:23,000 --> 00:06:29,000 Right. However, you know, if you think about the animals that are being hunted, some of them are quite large and you want a bigger wound. 114 00:06:29,000 --> 00:06:32,000 You want it to bleed out faster. So I think the arrowhead makes quite a difference. 115 00:06:32,000 --> 00:06:35,000 I mean, if you look here, yeah, look at that. 116 00:06:35,000 --> 00:06:40,000 There's the pointy stick wound. It's just a little hole and there's the arrowhead wound. It's nice and wide. 117 00:06:40,000 --> 00:06:45,000 But Jamie isn't impressed. In his mind, the size of the entry wound isn't the issue. 118 00:06:45,000 --> 00:06:54,000 In terms of penetration, it was only about 5% difference and yet it took a thousand percent longer to make this one than this one. 119 00:06:54,000 --> 00:07:00,000 So it may not just be about lethality. It might also be about accuracy. And that's what we have to test next. 120 00:07:00,000 --> 00:07:04,000 Yep, they're leaving no stone unturned for this myth. 121 00:07:04,000 --> 00:07:11,000 No, we haven't made this up. It's a myth straight from the fan site. 122 00:07:11,000 --> 00:07:17,000 For the next viewer myth, a fan wants to know if you can chop down a tree with a machine gun. 123 00:07:17,000 --> 00:07:21,000 Oh, just like in the movie Predator where they mow down a chunk of the jungle. 124 00:07:21,000 --> 00:07:28,000 Exactly. Oh my gosh, that's funny. You should say that because every time I go hiking in the forest and I'm just like, can I cut that tree down with a machine gun? 125 00:07:28,000 --> 00:07:31,000 Perfect. You're going to find out. 126 00:07:32,000 --> 00:07:42,000 Tree lovers, huggers and hippies beware. Torey's all fired up and ready to uproot this myth with some machine gun mayhem. 127 00:07:42,000 --> 00:07:46,000 Machine guns are a formidable weapon that have been in use for over a hundred years. 128 00:07:46,000 --> 00:07:55,000 Their deadly spray of bullets, lethal on the battlefield, is, or so the fans claim, the ideal tool for tree felling. 129 00:07:55,000 --> 00:07:58,000 So how are we going to test this myth because I don't want to go around destroying trees. 130 00:07:58,000 --> 00:08:04,000 Well, why don't we get some trees that have been freshly felled for clearing purposes, will create our own artificial forest. 131 00:08:04,000 --> 00:08:07,000 That way no trees will have been killed in the busting of this myth. 132 00:08:07,000 --> 00:08:12,000 I think to test this properly, we're going to need to get a bunch of machine guns and see if any of them will cut down a tree. 133 00:08:12,000 --> 00:08:19,000 You know, I think the kind of artillery that we're going to want to use to test this myth is something that's not going to be accessible in California. 134 00:08:19,000 --> 00:08:24,000 So I think we're going to have to go back to that secret location where Jamie and Adam tested shooting fish in a barrel. 135 00:08:24,000 --> 00:08:28,000 Ah, the secret location. I hope they allow us back. 136 00:08:28,000 --> 00:08:33,000 Who's with me? Come on everybody, get your guns. Let's go to the forest. Chop down the trees. 137 00:08:33,000 --> 00:08:39,000 Right there is the reason our insurance premiums are so high. So it's off for some fun in the Arizona sun. 138 00:08:39,000 --> 00:08:40,000 Are we going to have some fun? 139 00:08:40,000 --> 00:08:47,000 On scene at the secret location, the team need just two ingredients. Machine guns are no problem. 140 00:08:47,000 --> 00:08:52,000 But the tree line around here has flat line. So the guys pack their own. 141 00:08:52,000 --> 00:08:57,000 We have three freshly cut pine trees. Grant's digging holes right now so that we can stick them up. 142 00:08:57,000 --> 00:08:59,000 We're going to fire at them, see if we can cut them down. 143 00:08:59,000 --> 00:09:08,000 If they do, it won't be because they've selected saplings. These pine trees are fully two feet in diameter and two tons of piece. 144 00:09:08,000 --> 00:09:13,000 Among them, our boreal expert, Mark Maul, has planted an extra challenge. 145 00:09:13,000 --> 00:09:17,000 We have three freshly cut pine, but what's the tree at the end? 146 00:09:17,000 --> 00:09:20,000 The tree at the end is a native mesquite tree. 147 00:09:20,000 --> 00:09:24,000 Is that harder to cut through? Why do we have this one? 148 00:09:24,000 --> 00:09:30,000 It's about four times as dense as the pine tree and it's going to give the machine gun a run for its money. 149 00:09:30,000 --> 00:09:37,000 Yep, this hard core hardwood is as tough as timber gets, making it the ultimate challenge for the machine gun. 150 00:09:37,000 --> 00:09:42,000 But before either tree faces the firing squad, Tori takes us through the arsenal. 151 00:09:42,000 --> 00:09:48,000 Now, machine gun is very general term. So what we've done is we've chosen three different types to cover a very large range. 152 00:09:48,000 --> 00:09:52,000 For our small machine gun, we're going to go with the Thompson submachine gun. 153 00:09:52,000 --> 00:09:58,000 It shoots a .45 caliber round. This is like your classic gangster machine gun that you see in the 30s. 154 00:09:58,000 --> 00:10:02,000 The next, our medium range machine gun is called the SAW. How ironic. 155 00:10:02,000 --> 00:10:08,000 It's a squad automatic weapon and it shoots a .223 fully automatic. This one is going to be fun to shoot. 156 00:10:08,000 --> 00:10:12,000 Finally, for our big one, we're shooting the minigun. 157 00:10:12,000 --> 00:10:17,000 And this shoots a .30 caliber round, 3,000 rounds per minute. 158 00:10:17,000 --> 00:10:21,000 My money for cutting down a tree is on this bad boy right here. 159 00:10:21,000 --> 00:10:26,000 Still to come, the Mythbusters get fired up from machine gun mayhem. 160 00:10:26,000 --> 00:10:28,000 I want to make a withdrawal. 161 00:10:28,000 --> 00:10:44,000 Adam and Jamie have been asked by a fan why our ancient ancestors spent so much time making flint arrowheads. 162 00:10:44,000 --> 00:10:48,000 When sharpened sticks might have worked just as well. 163 00:10:48,000 --> 00:10:51,000 But the caveman jury is still out. 164 00:10:51,000 --> 00:10:57,000 Because in the so-called lethality testing, both arrow types were pretty much equal. 165 00:10:57,000 --> 00:10:59,000 So what's next? 166 00:11:09,000 --> 00:11:16,000 The whole point of this exercise is to find out if there's a point to the manufactured point on an ancient arrow. 167 00:11:16,000 --> 00:11:21,000 Now the question is, is one of these more accurate over distance? 168 00:11:21,000 --> 00:11:26,000 For that, they set up the Ninja Arrow Bot 55 feet from the target. 169 00:11:26,000 --> 00:11:29,000 But this time, the target has a tash. 170 00:11:29,000 --> 00:11:31,000 Where'd you find that picture? 171 00:11:34,000 --> 00:11:37,000 I dubbed this J-Man the Barbarian. 172 00:11:40,000 --> 00:11:45,000 With J-Man in place, Adam and Jamie line up for round one. 173 00:11:45,000 --> 00:11:49,000 They fire six of the stone tipped arrows in quick succession. 174 00:11:51,000 --> 00:11:53,000 Let's go take a look at those. 175 00:11:53,000 --> 00:11:55,000 So far so good. 176 00:11:55,000 --> 00:12:00,000 It still is quite deadly at 50 feet in hitting a large fleshy target like Mr. Heineman. 177 00:12:00,000 --> 00:12:07,000 Now the question is, will we be able to see any difference with the non-arrow headed tipped arrows? 178 00:12:07,000 --> 00:12:09,000 Sharpened sticks, fire one. 179 00:12:09,000 --> 00:12:12,000 In three, two, one. 180 00:12:12,000 --> 00:12:16,000 This time it's a volley of six sharpened sticks. 181 00:12:16,000 --> 00:12:19,000 Let's inspect. 182 00:12:19,000 --> 00:12:26,000 And just like in the lethality tests, they refuse to be significantly outperformed by their stony counterparts. 183 00:12:26,000 --> 00:12:29,000 Well, we've got one up here that's out by itself. 184 00:12:29,000 --> 00:12:31,000 Yeah, one bogey. 185 00:12:31,000 --> 00:12:36,000 But the rest are pretty much just as clustered as the arrow headed arrows. 186 00:12:36,000 --> 00:12:39,000 At this distance, it doesn't seem to me to be much of a difference. 187 00:12:39,000 --> 00:12:40,000 No. 188 00:12:40,000 --> 00:12:44,000 So in summary, are Stone Age scientists have tried lethality testing? 189 00:12:44,000 --> 00:12:46,000 Actually, they were very close. 190 00:12:46,000 --> 00:12:50,000 And only got a difference in the size of the entry wound. 191 00:12:50,000 --> 00:12:52,000 They tried testing accuracy. 192 00:12:52,000 --> 00:12:55,000 Please stop hitting me with arrows. 193 00:12:55,000 --> 00:12:56,000 That hurts. 194 00:12:56,000 --> 00:12:58,000 And got the same result. 195 00:12:58,000 --> 00:13:02,000 In terms of performance, the arrows are virtually the same. 196 00:13:02,000 --> 00:13:05,000 So how do we answer this Dr. Todd's fan fable? 197 00:13:05,000 --> 00:13:06,000 Well, here are the facts. 198 00:13:06,000 --> 00:13:12,000 It took more than ten times longer to make an arrow with an arrowhead on it than it did to make a sharpened stick. 199 00:13:12,000 --> 00:13:19,000 And yet, neither of them were any better than the other one as far as accuracy or penetration. 200 00:13:19,000 --> 00:13:23,000 Yes, but we did find that the arrowhead made a bigger wound. 201 00:13:23,000 --> 00:13:28,000 And that means that whatever you're hunting, whether it's a vison or a mammoth or what have you, 202 00:13:28,000 --> 00:13:31,000 that bigger wound is going to mean it bleeds out faster. 203 00:13:31,000 --> 00:13:34,000 And that means it's going to die quicker and you're going to eat sooner. 204 00:13:34,000 --> 00:13:36,000 And in the hunting game, baby, that's everything. 205 00:13:36,000 --> 00:13:41,000 And you also have to consider that the arrow shafts are made out of wood 206 00:13:41,000 --> 00:13:44,000 and if it's just a sharpened stick, it's going to rot. 207 00:13:44,000 --> 00:13:48,000 And the only thing that would be around for us to look at are these arrowheads. 208 00:13:48,000 --> 00:13:51,000 So we don't really know which there were more of. 209 00:13:51,000 --> 00:13:54,000 And here's one more argument in favor of the old arrowhead. 210 00:13:54,000 --> 00:13:57,000 And that is that this is technology. 211 00:13:57,000 --> 00:14:01,000 Back in the day, this puppy was caveman bullying. 212 00:14:01,000 --> 00:14:04,000 And like any technology, you've got to have the latest and the greatest. 213 00:14:04,000 --> 00:14:08,000 Oh, yeah, that's what brings on the caveman ladies. 214 00:14:13,000 --> 00:14:17,000 Chopping down trees is a backbreaking and dangerous job. 215 00:14:17,000 --> 00:14:19,000 But could there be a better way? 216 00:14:19,000 --> 00:14:24,000 MythBuster fans want to know if you could replace a saw with a machine gun. 217 00:14:24,000 --> 00:14:27,000 But enough shooting the breeze. How about them trees? 218 00:14:27,000 --> 00:14:32,000 OK, so our first weapon up today is the Thompson submachine gun. 219 00:14:32,000 --> 00:14:37,000 So grad hit man Imahara has the tree machine gun myth in his sights. 220 00:14:37,000 --> 00:14:45,000 He locks, he loads and lets loose with a drum full of 45 caliber bullets 221 00:14:45,000 --> 00:14:49,000 at 500 rounds a minute. 222 00:14:49,000 --> 00:14:54,000 But it's soon clear the handheld automatic is far from ideal. 223 00:14:55,000 --> 00:14:59,000 You know what? One thing I'm seeing with the machine gun, it's just tough to keep it on target 224 00:14:59,000 --> 00:15:03,000 because you constantly want to rise up. 225 00:15:03,000 --> 00:15:05,000 It just pushes you like that. 226 00:15:05,000 --> 00:15:08,000 It's going to be tough to hit the same spot on the tree. 227 00:15:08,000 --> 00:15:12,000 Yes, the kickback is making it tough for Grant to focus his fire. 228 00:15:12,000 --> 00:15:16,000 Which means it's time to up the ante. 229 00:15:16,000 --> 00:15:19,000 I want to make a withdrawal. Do you think you can help me? 230 00:15:19,000 --> 00:15:25,000 Story looking like a gun enthusiast magazine cover is confident the squad automatic weapon 231 00:15:25,000 --> 00:15:28,000 or the saw will live up to its name. 232 00:15:28,000 --> 00:15:31,000 You know with this machine gun I think we have a better chance of cutting down a tree 233 00:15:31,000 --> 00:15:35,000 just because these bullets are going to be flying at a lot faster velocity 234 00:15:35,000 --> 00:15:38,000 so they should be cutting through the tree. 235 00:15:38,000 --> 00:15:43,000 So Tori assumes the position and lets rip. 236 00:15:46,000 --> 00:15:50,000 After Grant's experience with the Tommy gun, Tori's using a bipod 237 00:15:50,000 --> 00:15:53,000 for increased stability and accuracy. 238 00:15:53,000 --> 00:15:55,000 It was great, you had a straight line. 239 00:15:55,000 --> 00:16:00,000 Tori works away, concentrating his fire in a line across the base of the trunk 240 00:16:00,000 --> 00:16:07,000 but despite unloading over three ammo belts into the wood, there's no sign of timber. 241 00:16:07,000 --> 00:16:11,000 Got them all right. I don't think it's going down though. 242 00:16:11,000 --> 00:16:14,000 And with one last blast Tori gives up. 243 00:16:14,000 --> 00:16:19,000 But unlike the Tommy gun, the saw bullets did go all the way through the trunk 244 00:16:19,000 --> 00:16:24,000 but the relatively small caliber 223 meant the damage was limited 245 00:16:24,000 --> 00:16:26,000 and the tree stayed standing. 246 00:16:26,000 --> 00:16:32,000 But the myth is still alive because Carrie Mad Max Byron is up next. 247 00:16:32,000 --> 00:16:39,000 After the break Adam and Jamie launch a spear campaign and Carrie brings out the big guns. 248 00:16:50,000 --> 00:16:59,000 Not so long ago the team went to the ball game to hit some baseball myths right out of the park 249 00:16:59,000 --> 00:17:03,000 but the fans say there was one glaring omission. 250 00:17:03,000 --> 00:17:05,000 Can you guess what's next? 251 00:17:05,000 --> 00:17:07,000 Let me see. 252 00:17:07,000 --> 00:17:08,000 Eye black? 253 00:17:08,000 --> 00:17:10,000 Good call. 254 00:17:10,000 --> 00:17:13,000 Well eye black is supposed to do what? Make you see better? 255 00:17:13,000 --> 00:17:14,000 Yeah by cutting the glare. 256 00:17:14,000 --> 00:17:20,000 Either that or it's supposed to strike the fear into your opponents because it looks like war paint. 257 00:17:20,000 --> 00:17:22,000 Well how are we going to test that? 258 00:17:22,000 --> 00:17:25,000 Well I think we should bring Jess into it and I think she should put some eye black on us 259 00:17:25,000 --> 00:17:29,000 and it's pretty simple. We go out into the sunlight and we take an eye test 260 00:17:29,000 --> 00:17:32,000 both with and without eye black on our face. 261 00:17:32,000 --> 00:17:36,000 Except we can't know which one we've got on. 262 00:17:36,000 --> 00:17:40,000 So for one of us she'll do eye black and for the other she'll do regular makeup. 263 00:17:40,000 --> 00:17:43,000 We won't know which one so the test will be blind. 264 00:17:43,000 --> 00:17:45,000 So to speak. 265 00:17:45,000 --> 00:17:47,000 Exactly. 266 00:17:47,000 --> 00:17:52,000 So outside Jess positions the eye chart so the guys will face directly into the sun. 267 00:17:52,000 --> 00:17:53,000 Close your eyes. 268 00:17:53,000 --> 00:17:58,000 Then she launches a smear campaign putting eye black on Adam. 269 00:17:58,000 --> 00:18:00,000 I've put makeup on Adam before. 270 00:18:00,000 --> 00:18:01,000 What was that? 271 00:18:01,000 --> 00:18:03,000 Oh you know. 272 00:18:03,000 --> 00:18:06,000 And ordinary makeup on Jamie. 273 00:18:06,000 --> 00:18:10,000 Remember they don't know which substance they've got on their faces. 274 00:18:10,000 --> 00:18:12,000 Oh it's bright outside. 275 00:18:12,000 --> 00:18:15,000 Then they take turns sitting Jess's eye exam. 276 00:18:15,000 --> 00:18:24,000 H-V-Z-D-S-N-C-V-K-D-O-N-V-C-S-V-D-V-O-H-C-S-R. 277 00:18:24,000 --> 00:18:28,000 I think that's the last line, the third to the last is the smallest one I can read. 278 00:18:28,000 --> 00:18:33,000 At the end of round one Adam and Jamie each made just a single mistake. 279 00:18:33,000 --> 00:18:36,000 Could you tell what you had under your eyes? 280 00:18:36,000 --> 00:18:39,000 Honestly I could not tell whether I had a light or dark color under my eyes. 281 00:18:39,000 --> 00:18:44,000 They swapped stripes and sit the test a second time. 282 00:18:44,000 --> 00:18:47,000 C-Z-S-H-N-E. 283 00:18:47,000 --> 00:18:50,000 Is Jamie finding it easier with the eye black on? 284 00:18:50,000 --> 00:18:52,000 N-C-V-K-D-C-S. 285 00:18:52,000 --> 00:18:54,000 Is Adam struggling with the glare? 286 00:18:54,000 --> 00:18:58,000 Now that his cheeks no longer bear the sooty swipe. 287 00:18:58,000 --> 00:19:01,000 H-V-O-N-V-O-H-C-S-V-D-V-O-H-C-S-R. 288 00:19:01,000 --> 00:19:03,000 How did you do on that last one? 289 00:19:03,000 --> 00:19:06,000 Well actually the results are the same. 290 00:19:06,000 --> 00:19:08,000 One wrong letter each. 291 00:19:08,000 --> 00:19:11,000 However, I really feel like I can see it better. 292 00:19:11,000 --> 00:19:13,000 Please tell me I'm wearing the eye black. 293 00:19:13,000 --> 00:19:15,000 No. 294 00:19:15,000 --> 00:19:18,000 Negative results. 295 00:19:18,000 --> 00:19:20,000 Is what's on me now a lighter color? 296 00:19:20,000 --> 00:19:26,000 No actually it's black and I think it really compliments the beret. 297 00:19:26,000 --> 00:19:30,000 So both feel the test was harder with the eye black on. 298 00:19:30,000 --> 00:19:35,000 But because the eye test is so subjective they decide to remove the human element. 299 00:19:35,000 --> 00:19:38,000 They're going to use a fake face with a fake tan. 300 00:19:38,000 --> 00:19:40,000 Not entirely awful. 301 00:19:40,000 --> 00:19:43,000 And insert a light meter into the eye socket. 302 00:19:43,000 --> 00:19:47,000 I've got a professional grade eye black from the Sporting & Store. 303 00:19:47,000 --> 00:19:49,000 Gonna take a reading with the light on. 304 00:19:49,000 --> 00:19:51,000 Without the eye black and with the eye black. 305 00:19:51,000 --> 00:19:53,000 Let's see if there's a difference. 306 00:19:53,000 --> 00:19:57,000 With a single light source beaming down on our one-eyed outfielder. 307 00:19:57,000 --> 00:20:02,000 It's now settled out at around 3,160 or so. 308 00:20:02,000 --> 00:20:04,000 The guys note down the reading. 309 00:20:04,000 --> 00:20:07,000 Measured in lux, with and without eye black. 310 00:20:07,000 --> 00:20:09,000 It's about the same. 311 00:20:09,000 --> 00:20:11,000 The difference in a couple of lux. 312 00:20:11,000 --> 00:20:13,000 You never notice it with your naked eye. 313 00:20:13,000 --> 00:20:19,000 So the eye black didn't affect the amount of light bouncing off the cheek and into the eyeball. 314 00:20:19,000 --> 00:20:22,000 Don't these guys normally wear baseball caps? 315 00:20:22,000 --> 00:20:23,000 Yeah. 316 00:20:23,000 --> 00:20:25,000 Let's put one on and see what happens. 317 00:20:25,000 --> 00:20:28,000 Maybe it's about the reflected light not the direct light. 318 00:20:28,000 --> 00:20:33,000 On goes the cap and without eye black the light meter hovers around 103 lux. 319 00:20:33,000 --> 00:20:37,000 Then being careful not to move the cap, Adam adds the pigment. 320 00:20:37,000 --> 00:20:39,000 It's pretty well stabilized. 321 00:20:39,000 --> 00:20:43,000 Well below 100 like you know 90 thereabouts. 322 00:20:43,000 --> 00:20:45,000 That's significant. 323 00:20:45,000 --> 00:20:46,000 Yeah. 324 00:20:46,000 --> 00:20:50,000 With the cap on the eye black definitely reduced the amount of reflected light. 325 00:20:50,000 --> 00:20:52,000 And let's face it. 326 00:20:52,000 --> 00:20:55,000 When did he allow to see a baseballer without his cap?

That was a stunning episode. 475 00:30:02,000 --> 00:30:05,000 Well, it's a cartoon thing. Let me set the scenario. 476 00:30:05,000 --> 00:30:08,000 You've got a keg of gunpowder. It's got a hole in it. 477 00:30:08,000 --> 00:30:11,000 It's leaking. You're walking along leaving a trail of gunpowder. 478 00:30:11,000 --> 00:30:13,000 Somebody sneaks up behind, lights the trail. 479 00:30:13,000 --> 00:30:18,000 It catches up with you, blows up the keg, and you get all toasty like they do in the cartoons. 480 00:30:18,000 --> 00:30:20,000 I love the way they do it. 481 00:30:20,000 --> 00:30:23,000 It's a cartoon caper the guys just can't resist. 482 00:30:23,000 --> 00:30:29,000 Our animated hero is carrying a powder keg, but unbeknownst to him, it's got a leak. 483 00:30:29,000 --> 00:30:32,000 The sneaky villain takes advantage. 484 00:30:32,000 --> 00:30:39,000 The sparks travel up the falling powder and our hero is barbecued cartoon style. 485 00:30:39,000 --> 00:30:42,000 To test this fun fable, they'll need a robot. 486 00:30:42,000 --> 00:30:46,000 An armored remote control robot, and a gunpowder. 487 00:30:46,000 --> 00:30:52,000 They'll need a robot. An armored remote control robot with a leaking powder keg attachment. 488 00:30:52,000 --> 00:30:55,000 This is made from an electric wheelchair base. 489 00:30:55,000 --> 00:30:58,000 It's radio controlled, computerized, and do anything that I want. 490 00:30:58,000 --> 00:31:03,000 But so that I don't destroy it, I'm going to build an armor cover for it. 491 00:31:03,000 --> 00:31:09,000 Just out of steel. And hopefully Sparky won't go away when the gunpowder does. 492 00:31:09,000 --> 00:31:15,000 There we have it. It's going to be like, run Sparky run. 493 00:31:15,000 --> 00:31:21,000 With Sparky dressed to kill, it's time to get this myth up and running. 494 00:31:21,000 --> 00:31:24,000 Starting of course with some bench tests. 495 00:31:24,000 --> 00:31:32,000 Well, the main question I want to answer here is, can the black powder leaking out of that barrel leave a line contiguous enough to ignite? 496 00:31:32,000 --> 00:31:38,000 That's the question. And after laying down a moving trail, it's time to fire up an answer. 497 00:31:38,000 --> 00:31:43,000 Firing in three, two, one. 498 00:31:46,000 --> 00:31:50,000 There you go. That's fine. I think that's good. 499 00:31:54,000 --> 00:32:00,000 Yes, the trail was continuous enough to let the flame burn along its length. So what's next? 500 00:32:02,000 --> 00:32:07,000 Now I feel like I know it would travel along the line, but I want to know if it would climb that line up into the keg. 501 00:32:07,000 --> 00:32:14,000 So I'd like to walk down halfway down the line, same as I did before, but park it, get out, light it, and see if it blows up the cone. 502 00:32:16,000 --> 00:32:21,000 That worked perfectly. 503 00:32:21,000 --> 00:32:26,000 Mythbusters and perfection.

It was like boom. 506 00:32:33,000 --> 00:32:35,000 A little pop at the end there. 507 00:32:35,000 --> 00:32:37,000 Tells me what I need to know. 508 00:32:45,000 --> 00:32:54,000 This is a zipline down to terra firma. Practicing this alpine escape on a circus high wire, Tori glided to the ground. 509 00:32:56,000 --> 00:33:03,000 Now to test this on a real mountain, but before leaving, a mysterious package has arrived at M7. 510 00:33:03,000 --> 00:33:05,000 I have a surprise for you. 511 00:33:05,000 --> 00:33:06,000 A dead body! 512 00:33:06,000 --> 00:33:09,000 This is not a coffin. This is the new buster. 513 00:33:09,000 --> 00:33:13,000 No way. Thank God. I'm so sick of putting him back together. 514 00:33:16,000 --> 00:33:17,000 That's cute. 515 00:33:17,000 --> 00:33:21,000 How cute is that? They gave him coveralls with Buster's name on it. 516 00:33:21,000 --> 00:33:22,000 Buster now. 517 00:33:22,000 --> 00:33:24,000 That's adorable. 518 00:33:24,000 --> 00:33:29,000 Let's take a moment to salute our former buster's dedication, 519 00:33:29,000 --> 00:33:30,000 Come on, buster! 520 00:33:30,000 --> 00:33:35,000 tireless work ethic, and positive attitude. 521 00:33:35,000 --> 00:33:37,000 Dang! He hit hard. 522 00:33:37,000 --> 00:33:41,000 Thanks a bunch, buddy. It's time for a well-earned retirement. 523 00:33:41,000 --> 00:33:43,000 That was cool. 524 00:33:44,000 --> 00:33:52,000 Being a former crash test dummy, Buster 2.0 is a well-qualified replacement, so he's being put straight to work. 525 00:33:52,000 --> 00:33:57,000 Before any of us try it, we're going to let Buster try it first so we can see how dangerous it is. 526 00:33:57,000 --> 00:34:05,000 Tori carefully replaces Buster's hands with metal clamps, tests his jeans grappling grip, 527 00:34:05,000 --> 00:34:07,000 Looks like it's going to hold on to me, 528 00:34:07,000 --> 00:34:09,000 and loads him into the van. 529 00:34:11,000 --> 00:34:16,000 Leaving Carrie at home to rest her sore leg, the guys head for the hills. 530 00:34:16,000 --> 00:34:22,000 The Sierra at Tahoe Resort is their destination, and despite knowing Buster will be going first, 531 00:34:22,000 --> 00:34:24,000 Tori's a little nervous. 532 00:34:24,000 --> 00:34:26,000 That's a lot steeper than I thought it was going to be. 533 00:34:26,000 --> 00:34:29,000 Yep, and we're doing it all the way from the top. 534 00:34:30,000 --> 00:34:33,000 When we were at Trapiz Arts, we found that an angle of 20 degrees, 535 00:34:33,000 --> 00:34:38,000 which is just enough to start sliding down the line with a pair of jeans when the line was greased. 536 00:34:40,000 --> 00:34:44,000 Here at Sierra at Tahoe, they have the same consistency grease. 537 00:34:44,000 --> 00:34:50,000 Just to hedge our bets, we've found a section of line close to the top that's at 25 degrees. 538 00:34:51,000 --> 00:34:57,000 At the top, Chief Rigor Lawrence and his crew are putting together a safety system of ropes and pulleys. 539 00:34:57,000 --> 00:35:00,000 These guys are here to make sure I don't fall to my death. 540 00:35:01,000 --> 00:35:08,000 Tori and Grant strap on their harnesses, secure themselves to the chair, hoist in Buster, and head downhill. 541 00:35:10,000 --> 00:35:12,000 Are we nuts or what? 542 00:35:12,000 --> 00:35:14,000 Oh my God. 543 00:35:15,000 --> 00:35:17,000 So what's the denim divination? 544 00:35:18,000 --> 00:35:24,000 The best case scenario for Buster is that he and his jeans will take a very quick ride down the line, 545 00:35:24,000 --> 00:35:26,000 slamming to the rollers at the end. 546 00:35:26,000 --> 00:35:34,000 And the worst case scenario is that he will rip through his jeans and probably plummet to his doom. 547 00:35:38,000 --> 00:35:44,000 When they reach the 25 degree mark, they sling over the jeans and secure them to Buster's clamp hands. 548 00:35:45,000 --> 00:35:51,000 Buster is ready to go. All we need to do is unhook him from the chair and release this ratchet strap. 549 00:35:52,000 --> 00:35:56,000 It's a long journey to the bottom, Buster. Don't forget to ride. 550 00:35:56,000 --> 00:36:00,000 In three, two, one, go. 551 00:36:06,000 --> 00:36:09,000 Nothing really happened. We pushed him off and he just stuck there. 552 00:36:09,000 --> 00:36:16,000 Even though Buster is only about 10 pounds lighter than Tori, his weight couldn't overcome the friction of the jeans on the cable. 553 00:36:16,000 --> 00:36:19,000 And he simply stuck on the line. 554 00:36:21,000 --> 00:36:23,000 What do we do now? 555 00:36:23,000 --> 00:36:25,000 How about help him down? 556 00:36:33,000 --> 00:36:41,000 Although Buster never lost his grip, he's a bit of a dummy and couldn't follow Tori's lead in creating his own momentum. 557 00:36:42,000 --> 00:36:45,000 Good job, buddy. Way to take one for the team. 558 00:36:45,000 --> 00:36:48,000 Question is, can Tori do any better? 559 00:36:48,000 --> 00:36:50,000 I don't know if I should have seen that. 560 00:36:50,000 --> 00:36:55,000 Stay tuned because coming right up, it's the explosive moment of truth for Sparky. 561 00:37:07,000 --> 00:37:13,000 The fans have a theory that if you pull off your jeans, you can pull off a daring denim escape. 562 00:37:13,000 --> 00:37:21,000 But Tori and Grant found that if you try to fly down a ski lift cable by the seat of your pants, the friction can fix you in place. 563 00:37:21,000 --> 00:37:23,000 Go. 564 00:37:25,000 --> 00:37:28,000 But they may have a way to fight it. 565 00:37:28,000 --> 00:37:33,000 Cue Tori for an attempted slide down the ski lift in hot pants. 566 00:37:33,000 --> 00:37:35,000 Well, they will be after all the friction. 567 00:37:35,000 --> 00:37:38,000 So let's flip the jeans over and try to fly. 568 00:37:38,000 --> 00:37:41,000 In three, two, one. 569 00:37:44,000 --> 00:37:46,000 Get that weight on those jeans. 570 00:37:48,000 --> 00:37:50,000 Nice. Nice. 571 00:37:51,000 --> 00:37:53,000 Very nice, but it's not easy. 572 00:37:53,000 --> 00:38:03,000 My hands are cramping up because I was holding onto the jeans so tight, but then I had to lift my weight off the jeans so that I could shimmy down the cable and then my arms started getting tired. 573 00:38:03,000 --> 00:38:08,000 Our little dungarees clad flying squirrel is plum tuckered out. 574 00:38:08,000 --> 00:38:10,000 And not only that, stuck. 575 00:38:10,000 --> 00:38:12,000 I can't, I'm stuck. See that? 576 00:38:12,000 --> 00:38:13,000 I see it. 577 00:38:13,000 --> 00:38:14,000 I'm letting go. 578 00:38:16,000 --> 00:38:21,000 The jeans themselves actually starting to roll up as they grab onto the cable. 579 00:38:21,000 --> 00:38:25,000 There's way too much friction in the system to be able to slide. 580 00:38:27,000 --> 00:38:28,000 So guys, how'd it go? 581 00:38:28,000 --> 00:38:31,000 It was a little disappointing and it was nothing like we imagined. 582 00:38:31,000 --> 00:38:33,000 You know you picture going out on a zipline. 583 00:38:33,000 --> 00:38:35,000 It took a lot more work than that. 584 00:38:35,000 --> 00:38:37,000 The jeans kept sticking to the cable. 585 00:38:37,000 --> 00:38:41,000 Using your clothing to escape a ski lift, bad idea. 586 00:38:41,000 --> 00:38:45,000 Either the clothing is going to rip or your arms are going to give out. 587 00:38:45,000 --> 00:38:47,000 So zipline jeans escaped. Busted. 588 00:38:47,000 --> 00:38:48,000 Busted. 589 00:38:48,000 --> 00:38:49,000 Busted. 590 00:38:58,000 --> 00:39:02,000 Jamie and Adam are tackling a tall tale of cartoon physics. 591 00:39:02,000 --> 00:39:09,000 Can a leaking trail of burning gunpowder catch up and blow up the moving powder keg? 592 00:39:09,000 --> 00:39:14,000 To find out, our animated duo are back at the Alameda Bomb Disposal range. 593 00:39:14,000 --> 00:39:16,000 We've come back to the bomb range. 594 00:39:16,000 --> 00:39:18,000 We're going to do the same setup as we did before. 595 00:39:18,000 --> 00:39:22,000 Plywood laid down for the gunpowder to go on, except this time the difference is, 596 00:39:22,000 --> 00:39:27,000 Sarky will be going full tilt with gunpowder leaking from his barrel. 597 00:39:27,000 --> 00:39:31,000 The question we wanted to answer is, will the lit trail catch up with him? 598 00:39:32,000 --> 00:39:35,000 This is tough because this is not a myth where we're working from an actual case 599 00:39:35,000 --> 00:39:38,000 that we've read about or a story someone's told us. 600 00:39:38,000 --> 00:39:40,000 This is like cartoon physics. 601 00:39:40,000 --> 00:39:46,000 So of course we're going to run into trouble between cartoon physics view of the world and the real world. 602 00:39:46,000 --> 00:39:49,000 And in the real world, we've got an outdoor thing. 603 00:39:49,000 --> 00:39:52,000 It's the only place we can do this experiment with black powder. 604 00:39:52,000 --> 00:39:55,000 And of course, outdoors there's going to be a breeze. 605 00:39:55,000 --> 00:39:58,000 With a tumbling trail of powder vulnerable to the wind, 606 00:39:58,000 --> 00:40:02,000 the guys carry out the final prep with one eye on the weather. 607 00:40:02,000 --> 00:40:05,000 Sparky's barrel is loaded with two pounds of gunpowder, 608 00:40:05,000 --> 00:40:10,000 and Adam rigs a remote ignition system to spark the powder trail to life. 609 00:40:10,000 --> 00:40:13,000 There you go. 610 00:40:13,000 --> 00:40:14,000 This is it. 611 00:40:14,000 --> 00:40:18,000 Jamie directs Sparky along the track, trailing his deadly trail. 612 00:40:18,000 --> 00:40:20,000 Then Adam lights her up. 613 00:40:20,000 --> 00:40:22,000 In three, two, one. 614 00:40:22,000 --> 00:40:28,000 But there's another problem. 615 00:40:28,000 --> 00:40:31,000 The sparks caught up with Sparky, 616 00:40:31,000 --> 00:40:35,000 but didn't travel up the falling powder and into the keg. 617 00:40:35,000 --> 00:40:41,000 Adam and Jamie's solution is to drill a larger hole for a more substantial leak. 618 00:40:41,000 --> 00:40:42,000 I'm on. 619 00:40:42,000 --> 00:40:47,000 But once again, our big bang junkies don't get no satisfaction. 620 00:40:47,000 --> 00:40:48,000 It didn't go. 621 00:40:48,000 --> 00:40:50,000 That sucker just wants to clog. 622 00:40:50,000 --> 00:40:51,000 Yep. 623 00:40:51,000 --> 00:40:53,000 Despite several more attempts, 624 00:40:53,000 --> 00:40:59,000 either the powder doesn't want to fall freely or stay lit all the way to the intended target. 625 00:40:59,000 --> 00:41:01,000 Wait. 626 00:41:01,000 --> 00:41:06,000 And although Adam's annoyed, he's adamant they can get this right. 627 00:41:06,000 --> 00:41:09,000 I don't think this is disproving the myth or saying that it's not possible. 628 00:41:09,000 --> 00:41:14,000 I don't think we're hitting our mark and I'm not ready to call it until I feel like we have. 629 00:41:14,000 --> 00:41:21,000 What Adam and Jamie need is an ingenious last minute plan to keep the powder flowing freely. 630 00:41:21,000 --> 00:41:24,000 The only thing I can think to do is put a shaker on it. 631 00:41:24,000 --> 00:41:27,000 And the only shaker I have is right here. 632 00:41:27,000 --> 00:41:29,000 That's really a shame to make this go away. 633 00:41:29,000 --> 00:41:31,000 It's a nice drill. 634 00:41:31,000 --> 00:41:34,000 It's the last chance for this viewer myth. 635 00:41:34,000 --> 00:41:39,000 Now or never, this is No Drill. 636 00:41:39,000 --> 00:41:41,000 Here we go. 637 00:41:41,000 --> 00:41:46,000 Yeah. 638 00:41:46,000 --> 00:41:49,000 That worked. 639 00:41:49,000 --> 00:41:56,000 Well, Sparky looks like he's, let me see if he's still alive. 640 00:41:56,000 --> 00:41:57,000 Success. 641 00:41:57,000 --> 00:41:59,000 The gunpowder trail worked. 642 00:41:59,000 --> 00:42:03,000 It caught up, it traveled up the link and it exploded the barrel. 643 00:42:03,000 --> 00:42:08,000 And what's more, Sparky and the drill have survived intact. 644 00:42:08,000 --> 00:42:10,000 Yay! 645 00:42:10,000 --> 00:42:13,000 Sparky survived, but this isn't about Sparky. 646 00:42:13,000 --> 00:42:16,000 This is about what if you were carrying that barrel?
