It is a military myth and it's about replacing your normal cooking fuel 38 00:01:39,000 --> 00:01:43,000 with something usually considered far more destructive. 39 00:01:43,000 --> 00:01:44,500 What are the explosives? 40 00:01:44,500 --> 00:01:47,000 Not just any explosive, your favorite. 41 00:01:47,000 --> 00:01:48,000 Well that would be C4. 42 00:01:48,000 --> 00:01:53,000 Exactly. The myth is that C4 is so stable, you can light it with a match 43 00:01:53,000 --> 00:01:55,500 and it will burn and cook your lunch. 44 00:01:55,500 --> 00:01:57,000 And it doesn't explode? 45 00:01:57,000 --> 00:02:01,000 It won't. Although you're told not to stomp on it or drop your pot on it 46 00:02:01,000 --> 00:02:03,000 because that could make it blow up. 47 00:02:03,000 --> 00:02:05,000 Well that would make for some hot chili. 48 00:02:05,000 --> 00:02:06,000 Indeed. 49 00:02:07,000 --> 00:02:11,000 C4. Not just the explosive of choice for the Mythbusters. 50 00:02:11,000 --> 00:02:14,000 When in doubt, C4. 51 00:02:15,000 --> 00:02:17,000 But also the military. 52 00:02:17,000 --> 00:02:21,000 But can C4's power be used another way? 53 00:02:21,000 --> 00:02:23,000 To cook with without exploding. 54 00:02:23,000 --> 00:02:25,000 That's great. 55 00:02:25,000 --> 00:02:27,000 Well there's two parts to this story. 56 00:02:27,000 --> 00:02:31,000 One is that supposedly you can light C4 on fire and it will burn without blowing up. 57 00:02:31,000 --> 00:02:35,000 And the second is that you better not drop a pot on it or stomp on it while it's on fire 58 00:02:35,000 --> 00:02:37,000 because that could make it blow up. 59 00:02:37,000 --> 00:02:38,000 I think we should test both of those. 60 00:02:38,000 --> 00:02:39,000 Sure. 61 00:02:41,000 --> 00:02:46,000 So to find out if this myth is cooking with gas or just a flash in the pan, 62 00:02:46,000 --> 00:02:50,000 the guys head to the safety of, you guessed it, a bomb range. 63 00:02:50,000 --> 00:02:52,000 Now before we get down to the business of testing this myth, 64 00:02:52,000 --> 00:02:55,000 let's reacquaint ourselves with C4, shall we? 65 00:02:55,000 --> 00:02:59,000 For this is not simply a stable high speed explosive in a plastic medium 66 00:02:59,000 --> 00:03:02,000 that you can mold into the shape of a bunny and blow up. 67 00:03:02,000 --> 00:03:04,000 Oh no. This is versatile stuff. 68 00:03:04,000 --> 00:03:07,000 Let's take a look at a simple C4 detonation. 69 00:03:07,000 --> 00:03:10,000 This is why the military likes C4. 70 00:03:10,000 --> 00:03:12,000 It can make things go away. 71 00:03:12,000 --> 00:03:14,000 That's one way to cut up a water ballon. 72 00:03:15,000 --> 00:03:18,000 But it's also a precision device too. 73 00:03:18,000 --> 00:03:23,000 This piece of metal bent into a W shape is going to cut this bar cleanly in half. 74 00:03:23,000 --> 00:03:25,000 That's right. W stands for... 75 00:03:25,000 --> 00:03:26,000 Hoop-a! 76 00:03:26,000 --> 00:03:27,000 Three, two... 77 00:03:30,000 --> 00:03:32,000 That is beautiful. 78 00:03:32,000 --> 00:03:34,000 Look at that nice clean cut. 79 00:03:34,000 --> 00:03:38,000 I could do a little better with a saw, but it does indeed work. 80 00:03:38,000 --> 00:03:41,000 Now that we've seen how it detonates, it's time to tackle our story, 81 00:03:41,000 --> 00:03:45,000 which simply stated is that this stuff, C4 plastic explosive, 82 00:03:45,000 --> 00:03:49,000 is stable enough to actually light on fire and heat your lunch with, 83 00:03:49,000 --> 00:03:52,000 that it will not blow up even if you set it on fire. 84 00:03:52,000 --> 00:03:54,000 That's what we're about to test. 85 00:03:55,000 --> 00:03:58,000 Okay, why might burning C4 explode? 86 00:03:58,000 --> 00:04:01,000 Well, heat causes molecules to become excited. 87 00:04:01,000 --> 00:04:04,000 The greater the heat, the more the molecule mania. 88 00:04:04,000 --> 00:04:09,000 And that can cause instability and possibly an explosion. 89 00:04:10,000 --> 00:04:15,000 So from the safety of their bunker and ignited by a remote neon transformer... 90 00:04:15,000 --> 00:04:18,000 You ready? Igniting C4. 91 00:04:18,000 --> 00:04:20,000 Seeing if it burns without blowing up. 92 00:04:20,000 --> 00:04:23,000 10, 3, 2, 1... 93 00:04:24,000 --> 00:04:26,000 It's burning. 94 00:04:26,000 --> 00:04:27,000 Wow. 95 00:04:28,000 --> 00:04:29,000 It's really burning. 96 00:04:29,000 --> 00:04:31,000 It burns hot. 97 00:04:31,000 --> 00:04:33,000 But blowing up, it ain't. 98 00:04:34,000 --> 00:04:36,000 I don't think I'd want to be next to that. 99 00:04:36,000 --> 00:04:38,000 I don't care what they say. 100 00:04:39,000 --> 00:04:43,000 The C4 burned at more than a thousand degrees, rapidly. 101 00:04:43,000 --> 00:04:45,000 And without a kaboom. 102 00:04:45,000 --> 00:04:48,000 That's very good news for this myth so far. 103 00:04:48,000 --> 00:04:51,000 Now that we know it burns, let's see how well it cooks. 104 00:04:54,000 --> 00:04:58,000 Meanwhile, Grant, Carrie and Tori are attempting to wrap their heads 105 00:04:58,000 --> 00:05:01,000 around a mysterious martial arts myth. 106 00:05:01,000 --> 00:05:03,000 Alright, K, what's with the cool costume? 107 00:05:03,000 --> 00:05:04,000 Take a deep breath. 108 00:05:04,000 --> 00:05:06,000 We're doing a kung fu myth. 109 00:05:06,000 --> 00:05:07,000 Yes! 110 00:05:07,000 --> 00:05:08,000 Which one? 111 00:05:08,000 --> 00:05:10,000 The Flying Guillotine. 112 00:05:10,000 --> 00:05:12,000 Ugh, I love that movie. 113 00:05:12,000 --> 00:05:14,000 Yes, that's the one where the guy has his weapon, it's like a hat. 114 00:05:14,000 --> 00:05:18,000 He throws it over the guy's head, and he pulls the chain, and it decapitates him. 115 00:05:18,000 --> 00:05:19,000 Calm down. 116 00:05:19,000 --> 00:05:21,000 Yeah, and not only that, but once you cut the head off, 117 00:05:21,000 --> 00:05:24,000 you can actually retrieve the head back to the thrower. 118 00:05:24,000 --> 00:05:26,000 Well, I think the cool thing is that this might be more than a movie myth. 119 00:05:26,000 --> 00:05:28,000 This might be an actual ancient weapon. 120 00:05:28,000 --> 00:05:29,000 It could work. 121 00:05:32,000 --> 00:05:35,000 Made famous by B-grade kung fu movies, 122 00:05:35,000 --> 00:05:39,000 the Flying Guillotine was a disc that, when thrown over the neck, 123 00:05:39,000 --> 00:05:42,000 would decapitate and capture the victim's head. 124 00:05:42,000 --> 00:05:45,000 But it might not just be a filmmaker's fantasy. 125 00:05:45,000 --> 00:05:51,000 Because legend has it, Emperor Yong Zheng commissioned the device in 1722. 126 00:05:51,000 --> 00:05:55,000 But unfortunately for the mythbusters, no drawings of the design survive. 127 00:05:56,000 --> 00:05:58,000 Okay, what a terrifying concept. 128 00:05:58,000 --> 00:06:00,000 Assassins that can behead you from a distance? 129 00:06:00,000 --> 00:06:03,000 Yeah, but you know what the real problem right now is finding a design. 130 00:06:03,000 --> 00:06:06,000 We've been through all these history books and found nothing. 131 00:06:06,000 --> 00:06:08,000 I mean, the only designs come from the movies themselves. 132 00:06:08,000 --> 00:06:10,000 I mean, we're on our own on this one. 133 00:06:10,000 --> 00:06:12,000 Alright, well why don't we come up with some prototypes? 134 00:06:12,000 --> 00:06:15,000 We can incorporate some ideas from the movies and come up with our own ideas 135 00:06:15,000 --> 00:06:17,000 and see which works best. 136 00:06:17,000 --> 00:06:20,000 So we might actually get to design our own Flying Guillotine. 137 00:06:20,000 --> 00:06:22,000 This is awesome. 138 00:06:22,000 --> 00:06:27,000 So in order to test whether the mythical Flying Guillotine was a viable assassination weapon, 139 00:06:27,000 --> 00:06:32,000 they're going to divide and compete to see if they can design their own Flying Guillotine. 140 00:06:33,000 --> 00:06:35,000 Based on four parameters. 141 00:06:35,000 --> 00:06:37,000 One, enough power to cut the head off. 142 00:06:37,000 --> 00:06:40,000 Two, it has to be light enough to be thrown. 143 00:06:40,000 --> 00:06:44,000 Three, it has to be safe enough to be deployed without cutting your own fingers off. 144 00:06:44,000 --> 00:06:48,000 And four, you have to have some means to retrieve the head. 145 00:06:48,000 --> 00:06:53,000 With each of them working alone, it's going to test the team's prototyping skills to the limit. 146 00:06:53,000 --> 00:06:58,000 Now, a traditional Guillotine gets its cutting force from the fact that they have a massive blade 147 00:06:58,000 --> 00:07:03,000 traveling a long distance to create enough force to chop a head off. 148 00:07:03,000 --> 00:07:08,000 We have to make our devices lightweight, and we only have about six inches of travel 149 00:07:08,000 --> 00:07:10,000 to create that same sort of force. 150 00:07:10,000 --> 00:07:18,000 In their respective corners of the shop, the guys begin by playing with ideas and concepts that may or may not work. 151 00:07:18,000 --> 00:07:21,000 Alright, so I had a great idea for Flying Guillotine. 152 00:07:21,000 --> 00:07:24,000 I asked the researchers to find me a bear trap. 153 00:07:24,000 --> 00:07:30,000 Hopefully this would have enough energy to actually crush through a person's head. 154 00:07:32,000 --> 00:07:39,000 Clearly there's enough force, but throwing this through the air could be problematic. 155 00:07:39,000 --> 00:07:43,000 Meaning it's going to be a try it and seek kind of process. 156 00:07:43,000 --> 00:07:45,000 Yeah! 157 00:07:45,000 --> 00:07:49,000 Sometimes in the design process, you just have to get in there and get your hands dirty. 158 00:07:49,000 --> 00:07:54,000 Because there are no historical documents, no blueprints, no plans for Flying Guillotine, 159 00:07:54,000 --> 00:07:59,000 we're just going to have to figure this out as we go, which is going to mean a lot of trial and error. 160 00:07:59,000 --> 00:08:01,000 Probably mostly error. 161 00:08:01,000 --> 00:08:06,000 And that's immediately clear from Cary's first fiddle with a fan from an air conditioning duct. 162 00:08:06,000 --> 00:08:10,000 It's hard to use, it's getting heavy, and I just don't think it's going to work. 163 00:08:10,000 --> 00:08:13,000 So it's back to square one for Cary. 164 00:08:13,000 --> 00:08:20,000 And likewise on Bellegy's bench, this lethal looking scissor prototype he's made is also a dud. 165 00:08:20,000 --> 00:08:26,000 My Flying Guillotine doesn't work at all. I mean it kind of looks cool, 166 00:08:26,000 --> 00:08:33,000 but if you put something inside of it, like that's the safest place to be. 167 00:08:33,000 --> 00:08:40,000 Despite the pressure of their early designs failing on several fronts, the guys aren't deterred. 168 00:08:40,000 --> 00:08:42,000 I'm not the kind of the whole new design. 169 00:08:42,000 --> 00:08:47,000 Learning from your failures is all part of the prototype process, which is exactly what Cary does 170 00:08:47,000 --> 00:08:50,000 by opting for a far simpler concept. 171 00:08:50,000 --> 00:08:56,000 Picture a cigar cutter.
