69 00:05:18,880 --> 00:05:20,880 This is next. It's called data sheet. 70 00:05:20,880 --> 00:05:23,880 It's a high explosive in sheet form. 71 00:05:23,880 --> 00:05:26,880 We put this on top of our steel plate. 72 00:05:26,880 --> 00:05:28,880 Okay, that ought to work. 73 00:05:28,880 --> 00:05:29,880 And it goes kaboom. 74 00:05:29,880 --> 00:05:32,880 Yep, by adding a four-mil layer of data sheet, 75 00:05:32,880 --> 00:05:38,880 Jamie's hoping to force the upper steel plate down to completely crush his scale car. 76 00:05:39,880 --> 00:05:46,880 Fire the hole! Fire the hole! Fire the hole! 77 00:05:46,880 --> 00:05:48,880 Here we go. 78 00:05:50,880 --> 00:05:57,880 Okay, single layer of data sheet in three, two, one. 79 00:05:58,880 --> 00:06:01,880 Yeah, that's aggressive. 80 00:06:01,880 --> 00:06:03,880 That's got a real ring to it. 81 00:06:03,880 --> 00:06:06,880 I felt the walls of this thing vibrate. 82 00:06:06,880 --> 00:06:08,880 Yeah, let's go check it out. 83 00:06:10,880 --> 00:06:13,880 The data sheet sure packed a punch, 84 00:06:13,880 --> 00:06:16,880 but has it created a small-scale crush? 85 00:06:16,880 --> 00:06:20,880 That looks like a positive result there, Mr. Heidemann. 86 00:06:22,880 --> 00:06:25,880 That's like one of the wheels right there. 87 00:06:25,880 --> 00:06:27,880 And... 88 00:06:27,880 --> 00:06:28,880 That's the engine. 89 00:06:28,880 --> 00:06:29,880 The engine. 90 00:06:29,880 --> 00:06:33,880 Did you expect such a spectacular result on the first try? 91 00:06:33,880 --> 00:06:38,880 No, actually. I'm actually a little speechless. 92 00:06:39,880 --> 00:06:45,880 At a little under an inch thick, the car's been crushed to one-fifth its original size. 93 00:06:45,880 --> 00:06:49,880 So, is it already time to go full-scale? 94 00:06:49,880 --> 00:06:52,880 Jamie came here with a goal to flatten the car. 95 00:06:52,880 --> 00:06:55,880 And for my money, it looks like he achieved it on the very first try, 96 00:06:55,880 --> 00:06:59,880 but he's here at the bomb range, he's got a bunch of analogs. 97 00:06:59,880 --> 00:07:02,880 My guess is, I don't know, maybe he's going to start stacking them 98 00:07:02,880 --> 00:07:06,880 and trying to see optimal relationships between weight and explosives. 99 00:07:06,880 --> 00:07:08,880 Or maybe we're all just going to go home. 100 00:07:08,880 --> 00:07:11,880 I'm actually not sure at this point. 101 00:07:11,880 --> 00:07:13,880 Oh, we're not going home. I can tell you that much. 102 00:07:13,880 --> 00:07:14,880 Oh, come on! 103 00:07:14,880 --> 00:07:20,880 This was a lovely first attempt, but when we scale this up to a full-sized car, 104 00:07:20,880 --> 00:07:25,880 it's going to be a lot bigger of an experiment, a lot more time and difficulty. 105 00:07:25,880 --> 00:07:30,880 So, I want to learn everything I can about the dynamics of what happened here before we go there. 106 00:07:31,880 --> 00:07:34,880 In other words, small scale's not over yet. 107 00:07:34,880 --> 00:07:37,880 Whoa! I don't think they've landed yet. 108 00:07:37,880 --> 00:07:44,880 But first, it's time for Adam's destructive denouement. 109 00:07:44,880 --> 00:07:47,880 It's a nice little bit of symmetry in this episode, 110 00:07:47,880 --> 00:07:51,880 and you're happy trying to make a car as low into the ground as possible and in my house? 111 00:07:51,880 --> 00:07:53,880 You're trying to lift a car up as high as possible. 112 00:07:53,880 --> 00:07:54,880 Exactly. 113 00:07:54,880 --> 00:07:55,880 With a vacuum. 114 00:07:55,880 --> 00:07:58,880 Yes. Now, I figure that the trick to this is to make the mother of all attachments 115 00:07:58,880 --> 00:08:01,880 to increase the surface area of the vacuum cleaner's input 116 00:08:01,880 --> 00:08:04,880 so that the amount of such an eye create exceeds the weight of the car, 117 00:08:04,880 --> 00:08:06,880 and thus I can get it off the ground. 118 00:08:06,880 --> 00:08:11,880 So, what you're trying to say is that as far as the attachment goes, size matters. 119 00:08:11,880 --> 00:08:12,880 Indeed it does. 120 00:08:14,880 --> 00:08:22,880 Throughout Mythbusters history, vacuum cleaners have been blown up, turned into jet engines, 121 00:08:22,880 --> 00:08:27,880 didn't really jet across the room, and had the chance to bite back. 122 00:08:27,880 --> 00:08:28,880 I got bit. 123 00:08:28,880 --> 00:08:29,880 You guys are suck-believing. 124 00:08:29,880 --> 00:08:34,880 But can a single vacuum really have enough suck to lift a car? 125 00:08:34,880 --> 00:08:36,880 Get out! 126 00:08:38,880 --> 00:08:44,880 To find out if this impossible sounding tall tail can be true, the guys are starting small 127 00:08:44,880 --> 00:08:49,880 with a standard vacuum and hose trying to lift a five pound weight, 128 00:08:49,880 --> 00:08:53,880 which eventually it does. 129 00:08:53,880 --> 00:08:57,880 Okay, so that's just barely enough to hold on to that five pound. 130 00:08:57,880 --> 00:08:58,880 It is. 131 00:08:58,880 --> 00:09:03,880 We just shown that this common vacuum cleaner is able to lift a five pound weight on the end of its hose. 132 00:09:03,880 --> 00:09:07,880 Now the surface area on the end of the hose is 1.75 inches. 133 00:09:07,880 --> 00:09:13,880 So doing the math, that means that it's pulling about 2.8 pounds per square inch. 134 00:09:13,880 --> 00:09:17,880 So how are we going to lift a car that weighs 2600 pounds? 135 00:09:17,880 --> 00:09:19,880 Well, all you need is more square inches. 136 00:09:19,880 --> 00:09:25,880 In fact, if we have up to about a thousand square inches of suction area on the car, 137 00:09:25,880 --> 00:09:28,880 we should be able to lift it, in theory. 138 00:09:29,880 --> 00:09:36,880 The mythbusters are banking on the idea that the relationship between lift and surface area is linear, 139 00:09:36,880 --> 00:09:39,880 meaning if one square inch can lift 2.8 pounds, 140 00:09:39,880 --> 00:09:46,880 a single vacuum with a 1000 square inch footprint should be able to lift a car. 141 00:09:46,880 --> 00:09:52,880 But to test that crazy concept, the guys must next up the ante 142 00:09:52,880 --> 00:09:56,880 by building a larger than life vacuum attachment. 143 00:09:56,880 --> 00:09:58,880 This is one of the stranger things we've built. 144 00:09:58,880 --> 00:10:03,880 At eight inches in diameter, it should put their previous test in the shade. 145 00:10:03,880 --> 00:10:04,880 I hope that works. 146 00:10:05,880 --> 00:10:10,880 But so that it still fits the vacuum cleaner, Janie is building a manifold. 147 00:10:10,880 --> 00:10:11,880 There we go. 148 00:10:11,880 --> 00:10:15,880 That will link the cleaner to the cup with no loss of suction. 149 00:10:15,880 --> 00:10:16,880 I'll do it. 150 00:10:17,880 --> 00:10:19,880 The question is, will it work? 151 00:10:20,880 --> 00:10:22,880 All right, so here is a proof of concept. 152 00:10:22,880 --> 00:10:25,880 This is the PVC pipe cap that we put a gasket on, 153 00:10:25,880 --> 00:10:28,880 and here is the hose through which we'll be pulling our vacuum. 154 00:10:28,880 --> 00:10:33,880 Ah, the vacuum here is the household vacuum that we are going to use 155 00:10:33,880 --> 00:10:35,880 in order to adapt from this to this. 156 00:10:35,880 --> 00:10:40,880 Janie has built a manifold, so the manifold is going to go in there, 157 00:10:40,880 --> 00:10:47,880 and then that goes in there, and I've got a 50 pound weight to try and lift. 158 00:10:50,880 --> 00:10:51,880 Let's see if this works. 159 00:10:53,880 --> 00:10:54,880 Hey! 160 00:10:56,880 --> 00:10:57,880 Nice! 161 00:10:58,880 --> 00:11:02,880 In theory, I think this should be able to hold more than twice that. 162 00:11:02,880 --> 00:11:03,880 That's a lot of force. 163 00:11:03,880 --> 00:11:04,880 You'll feel it. 164 00:11:04,880 --> 00:11:09,880 Incredibly, their vacuum rig is lifting the 50 pounds with room to spare. 165 00:11:09,880 --> 00:11:10,880 That is awesome! 166 00:11:11,880 --> 00:11:13,880 At least until they pull the plug. 167 00:11:17,880 --> 00:11:18,880 So what's next? 168 00:11:18,880 --> 00:11:22,880 So, Jamie and I did a proof of concept 8 inch PVC cup, 169 00:11:22,880 --> 00:11:26,880 and it works so well, this is going to be our method for lifting the car. 170 00:11:26,880 --> 00:11:27,880 Why reinvent the wheel?
