1 00:00:00,000 --> 00:00:02,000 I 2 00:00:25,120 --> 00:00:27,120 Yep 3 00:00:30,840 --> 00:00:32,840 All right, let's see it 4 00:00:34,160 --> 00:00:39,680 What tell me bears. Yep, it's a fan favorite. All right, let's do this thing 5 00:01:00,000 --> 00:01:02,000 I 6 00:01:11,200 --> 00:01:15,240 Hope you're feeling pretty smart Jamie why because in this final season episode 7 00:01:15,240 --> 00:01:17,920 We're gonna have to behave like actual rocket scientists 8 00:01:18,480 --> 00:01:25,600 Excellent. What do you got? Well as you know throughout the history of mythbusters our relationship to rocketry has been a little bit like a Clint Eastwood movie 9 00:01:25,640 --> 00:01:27,640 There's been some good 10 00:01:28,440 --> 00:01:33,840 There's been some bad and a whole lot of the ugly 11 00:01:35,720 --> 00:01:41,760 This episode we hope to put it all together for an awesome fan favorite myth about non-standard rocket fuels 12 00:01:41,760 --> 00:01:48,080 I'm gonna go out on a limb here and guess that it's gummy bears. It is Sherlock. You're absolutely right 13 00:01:48,080 --> 00:01:51,120 Well, they do have a lot of calorific energy right and if it's true 14 00:01:51,120 --> 00:01:55,380 Just imagine we could fly to the moon on a rocket tail of pure sugary goodness 15 00:01:55,820 --> 00:01:58,060 That I like I thought you would 16 00:02:02,660 --> 00:02:06,860 Rockets a crowning majestic technological achievement 17 00:02:09,940 --> 00:02:15,380 Their harnessed explosive energy is capable of taking us out of this world 18 00:02:20,300 --> 00:02:25,020 This potential has led the mythbusters to fire a fearsome variety of rocketry 19 00:02:26,220 --> 00:02:27,720 Whoa 20 00:02:27,720 --> 00:02:29,720 And they've learned a thing or two 21 00:02:31,940 --> 00:02:33,940 Rockets are bombs with wings 22 00:02:35,020 --> 00:02:42,200 Total explosion upon ignition and a successful launch generally requires real rocket fuel 23 00:02:44,700 --> 00:02:49,780 So to test this fan requested tall tail of gummy bear powered propulsion 24 00:02:50,220 --> 00:02:53,380 Let's get things rolling with our resident rocket scientist 25 00:02:54,300 --> 00:02:58,860 Since we will be building rockets all episode long we thought it was important to start by defining our terms 26 00:02:58,900 --> 00:03:04,740 This is not an unreasonable depiction of the kind of rocket will use fiberglass body about seven feet long 27 00:03:04,740 --> 00:03:11,740 But it's the inside that really sets it apart now the business end where the exhaust comes out is called the fuel grain and the fuel 28 00:03:11,740 --> 00:03:15,140 Grain of this rocket like our Civil War one is made of paraffin 29 00:03:15,140 --> 00:03:20,580 But it's what sprays into the fuel grain that makes this a hybrid rocket and that is this a 30 00:03:21,020 --> 00:03:23,700 pressurized canister of liquid oxygen or locks 31 00:03:25,140 --> 00:03:33,300 Now when the locks is sprayed down through the paraffin and ignited it burns very fast and very hot and when it sprays out that nozzle 32 00:03:33,300 --> 00:03:36,380 It causes a reaction which sends this rocket into the sky 33 00:03:37,580 --> 00:03:44,780 The only difference between this hybrid rocket and the one we'll be making is that ours will be powered by delicious delicious candy 34 00:03:46,860 --> 00:03:48,860 No one tastes powerful 35 00:03:48,980 --> 00:03:52,820 That's the hybrid hardware, but the fable is fuel focused 36 00:03:53,300 --> 00:03:58,260 So it's out with the standard paraffin wax and in with the edible alternative 37 00:04:00,260 --> 00:04:05,780 Question is how do they make a fuel grain out of gummy bears? So this is how this whole thing works 38 00:04:06,100 --> 00:04:12,380 This is the rocket engine liner now. We're gonna fill this with gummy bears, but we're not gonna fill it solid 39 00:04:12,380 --> 00:04:18,060 We need to actually have a tube down the middle through which the liquid oxygen will flow so to create that 40 00:04:18,060 --> 00:04:23,580 I'm gonna insert this white plastic tube with a spacer disc so it's held in the middle 41 00:04:23,580 --> 00:04:26,820 We put the gummy bears in there and we're good to go 42 00:04:31,620 --> 00:04:33,620 Hello, oh hey 43 00:04:33,900 --> 00:04:35,900 Are we ready for this you got the mold? 44 00:04:36,500 --> 00:04:40,820 With the mold made the guys start by simply jamming the gummies in manually 45 00:04:41,020 --> 00:04:43,860 Although this won't be their only method of making the fuel grain 46 00:04:44,860 --> 00:04:50,500 Oh, okay close packing them in so tightly means there's more energy per cubic inch 47 00:04:51,100 --> 00:04:53,420 This episode sponsored by the American Dental Association 48 00:04:54,140 --> 00:04:58,380 But removing any air pockets is important too in our experience 49 00:04:58,900 --> 00:05:06,620 Airspaces in a rocket fuel grain are bad because there are places where the burning can propagate and create too much surface area 50 00:05:07,180 --> 00:05:09,060 Shove your candy in that hole 51 00:05:09,060 --> 00:05:14,980 Everything about a rocket burning is about controlling the burn and when you have too much surface area that burn can get out of control 52 00:05:14,980 --> 00:05:18,580 And really its failure mode is to blow up your rocket. That's bad 53 00:05:23,340 --> 00:05:24,980 All right 54 00:05:24,980 --> 00:05:29,820 That's one engine, but they've got two more in mind now Jamie and I are gonna cook two 55 00:05:30,100 --> 00:05:34,860 Different fuel grains and here's where things start to get interesting in the myth busters rocket kitchen 56 00:05:34,860 --> 00:05:41,180 See a hybrid fuel grain works better the more consistent it is therefore our second rocket is gonna be a contiguous 57 00:05:41,700 --> 00:05:44,780 Single-gummy rocket. We're gonna gently heat up the gummy bears. Ooh 58 00:05:46,500 --> 00:05:49,820 As soon as that mass is melted we're gonna pour it into the mold 59 00:05:51,540 --> 00:06:00,380 Ah nice and voila what we should get out is a fuel grain sized single gum nice control there Heinemann 60 00:06:00,820 --> 00:06:05,900 When Jamie comes from seven generations of candy makers 61 00:06:07,780 --> 00:06:09,780 So there's an engine 62 00:06:11,780 --> 00:06:16,260 Potential engine for the third fuel grain we're sticking to the spirit of the myth 63 00:06:16,260 --> 00:06:21,100 Which is gummy bear rocket fuel, but we're gonna cheat a little bit because of some basic chemistry 64 00:06:21,580 --> 00:06:28,240 These guys are mostly gelatin which is mostly water the last time I checked water doesn't burn very well 65 00:06:28,440 --> 00:06:35,080 So we're gonna boil as much water off as we can pour the syrup into a mold and let it set into a hard rock candy 66 00:06:35,600 --> 00:06:37,600 Now we wait 67 00:06:38,520 --> 00:06:44,880 But gently boiling the mixture at 250 degrees overnight has not given the guys the result they require 68 00:06:44,920 --> 00:06:49,240 This could not be farther away from hard candy 69 00:06:50,040 --> 00:06:57,840 But we called a candy expert and the trick is to get the candy between 300 and 310 degrees Fahrenheit 70 00:06:58,960 --> 00:07:02,520 Adam begins by testing the new technique in small scale and 71 00:07:03,280 --> 00:07:08,800 Things are getting a little more serious make no mistake. This candy is super dangerous 72 00:07:08,800 --> 00:07:15,320 It's a super heated syrup if it got on you third degree burns a trip to the hospital and a permanent scar 73 00:07:16,480 --> 00:07:23,320 305 okay excellent if it got on Jamie wouldn't be any problem. We just peel off the skin off of his exo skeleton and they repair it 74 00:07:23,640 --> 00:07:25,640 I 75 00:07:27,320 --> 00:07:29,320 Good I'm good. I'm totally good 76 00:07:32,240 --> 00:07:34,080 Wow 77 00:07:34,080 --> 00:07:38,840 Okay, I'm just gonna cool this down because I've got a compressed gas cylinder over there 78 00:07:42,200 --> 00:07:45,840 Take two all right welcome back to how to ruin kitchen equipment 79 00:07:47,200 --> 00:07:50,540 Now I'm about to heat up a bunch more candy using this big 80 00:07:51,340 --> 00:07:54,660 Non-glass container I've learned from my mistakes 81 00:08:02,300 --> 00:08:04,140 Wow 82 00:08:04,140 --> 00:08:07,540 Boiling at the target temperature for an hour releases all of the water 83 00:08:08,900 --> 00:08:16,180 Just hold on to that while I pour and given the potential dangers the Heidemann steps in to help with the handling of the super heated syrup 84 00:08:17,300 --> 00:08:19,300 That's awesome 85 00:08:21,540 --> 00:08:24,940 Jamie I think this might be the worst mess I've ever made in your shop. I 86 00:08:26,300 --> 00:08:28,300 Don't know 87 00:08:28,380 --> 00:08:32,460 You'd have to think about it. I have to think about that you've made some pretty significant messes 88 00:08:41,500 --> 00:08:46,380 But with no further mishaps or mess their work here is done there we go 89 00:08:47,340 --> 00:08:52,820 Well, that was a lot more work than we anticipated but we finally have our three rocket grains 90 00:08:52,820 --> 00:08:57,940 We've got the hand-packed gummies. We got the contiguous single gummy and we've got the hard crack candy 91 00:08:57,940 --> 00:09:01,100 That's all we can do here in the shop now. It's time to head out to the desert 92 00:09:17,380 --> 00:09:24,660 Now as anyone who makes gummy bear rockets will tell you actually it might be the first but as will tell you once you've completed your gummy bear rocket 93 00:09:24,660 --> 00:09:29,500 You're going to need a place to fire it and in the Mojave desert at the edge of the Coen dry lake bed 94 00:09:29,500 --> 00:09:32,940 We are on the compound of the Friends of Amateur Rocketry 95 00:09:34,300 --> 00:09:39,560 This is it a little nowhere what makes this place so special is not only their 96 00:09:39,980 --> 00:09:45,780 Incredible expertise in rocketry, but it is on this exact location. We fired the Chinese rocket chair more than a decade ago 97 00:09:46,620 --> 00:09:48,620 and 98 00:09:50,860 --> 00:09:57,660 They hand-built the rockets for our third and final attempt to fire a car across the desert the J-03 episode 99 00:10:00,660 --> 00:10:08,860 Welcome to the Mythbusters Mojave HQ the launch pad location for some spectacular final season rocket science research 100 00:10:09,660 --> 00:10:13,660 Can gummy bears really fuel a liquid oxygen hybrid rocket? 101 00:10:16,620 --> 00:10:20,460 To coming up it gets real 102 00:10:28,140 --> 00:10:30,140 It's gotta go 103 00:10:40,700 --> 00:10:42,700 Majestic and magnificent 104 00:10:43,660 --> 00:10:49,980 Rockets are defined as a vehicle propelled by thrust rock one from burning on board fuel 105 00:10:51,500 --> 00:10:57,260 Any fuel and the most unlikely of all the mythical gummy bear 106 00:10:58,500 --> 00:11:04,900 So we've got three different versions of our gummy bear rockets those are gonna go into these four-inch rocket casings 107 00:11:05,700 --> 00:11:12,340 Inside this is a tank of liquid oxygen a valve and the rocket engine with the gummy bears 108 00:11:12,340 --> 00:11:17,420 And then the rocket nozzle those are all the major components that go into a hybrid rocket 109 00:11:18,940 --> 00:11:23,900 Now if you remember it's a hybrid rocket because we're feeding liquid oxygen through our fuel grain 110 00:11:23,900 --> 00:11:30,540 And that's what this giant tank is full of liquid oxygen literally some of the scariest stuff on earth 111 00:11:30,700 --> 00:11:36,540 To say this is flammable is really it's not accurate because this is what makes things flammable 112 00:11:36,540 --> 00:11:40,660 It is the enabler for burning which is exactly what it's doing in our rockets 113 00:11:42,340 --> 00:11:46,260 With the locks and rocket casing ready to roll cue the first fuel 114 00:11:46,820 --> 00:11:48,820 hand-packed gummies 115 00:11:48,900 --> 00:11:54,420 Isn't that pretty that is gorgeous. So the gummy bear fuel grain is going into its housing 116 00:11:55,220 --> 00:12:02,020 There are a lot of fiddly bits that all have to work perfectly in concert snap rings o rings 117 00:12:02,420 --> 00:12:06,180 Rocket grains housing and everything and it all has to be properly assembled 118 00:12:07,460 --> 00:12:09,460 With the engine loaded and locked 119 00:12:10,100 --> 00:12:12,100 It's go time for launch 120 00:12:12,660 --> 00:12:16,980 This is the pre-launch setup we mount the rocket 121 00:12:19,620 --> 00:12:24,460 Insert the altimeter and the descent parachute into the nose cone and then erect guide rail 122 00:12:30,060 --> 00:12:32,580 After that we de-ass the area 123 00:12:35,820 --> 00:12:37,820 Here we go 124 00:12:37,860 --> 00:12:41,420 Because just as our bomb squad so the only ones qualified due to the final 125 00:12:41,660 --> 00:12:47,940 Capping in of explosives our rocket techs here are the only ones qualified to work with the super unstable liquid oxygen 126 00:12:48,020 --> 00:12:49,740 Once they have the locks in place 127 00:12:49,740 --> 00:12:55,180 They put in the ignition system and the countdown sequence begins it ends of course with me counting from five 128 00:12:55,620 --> 00:12:58,100 Two zero and I hit the launch button the moment 129 00:12:58,100 --> 00:13:04,020 I do an igniter starts a little fire in the base of the rocket at the same time a valve opens up and liquid oxygen begins 130 00:13:04,020 --> 00:13:09,620 To spray down the middle of the core of our fuel grain it is ignited by that flame and hopefully also in turn 131 00:13:09,860 --> 00:13:16,420 Ignites the fuel grain causing a chain reaction of explosive force that sends the rocket skyward system is armed 132 00:13:17,380 --> 00:13:23,500 Theoretically this is it will hand-packed gummy bears be a viable rocket fuel 133 00:13:34,020 --> 00:13:36,020 Come on baby 134 00:13:41,380 --> 00:13:43,380 That's the sound of 135 00:13:44,100 --> 00:13:46,600 Not working. It's the sound of failure 136 00:13:50,260 --> 00:13:54,260 Well, we just fired our first gummy bear rocket and remember these were the gummy bears 137 00:13:54,260 --> 00:13:58,860 We're just jammed into a rocket grain shape with no other modification and 138 00:13:59,540 --> 00:14:04,580 We got a successful firing which is we heard it burn and shoot out some fire 139 00:14:04,580 --> 00:14:10,700 And then you started to hear the telltale sound of gummy bears individually peeling off from the rocket grain 140 00:14:11,180 --> 00:14:16,700 And getting pooped out of the bottom of our rocket, but not with enough force to actually lift this rocket 141 00:14:16,700 --> 00:14:19,300 We didn't get any else. We didn't get one inch. Yeah 142 00:14:22,940 --> 00:14:28,260 The ignition flame appeared to light the locks. Oh nice you're eating it 143 00:14:28,980 --> 00:14:35,020 We I'd still sweet Wow, but they'll lose packed flavorsome fuel simply fell apart 144 00:14:37,580 --> 00:14:43,380 Q gummy bear fuel number two this time we're using the melted gummy bears remember 145 00:14:43,380 --> 00:14:48,220 It's one solid contiguous gummy material molded into a tube shape 146 00:14:48,820 --> 00:14:51,860 I'm marginally more optimistic about this time. I 147 00:14:54,540 --> 00:14:57,460 Got a rocket in my pocket and I'm ready for some action 148 00:14:58,940 --> 00:15:04,340 I'm getting more and more excited the rocket grain is in there. I'm feeling very optimistic 149 00:15:06,540 --> 00:15:08,540 And sneeze 150 00:15:09,660 --> 00:15:11,660 There you go 151 00:15:12,300 --> 00:15:17,420 With the rocket ready for launch back at mission control it's countdown number two 152 00:15:17,820 --> 00:15:22,620 All right, here we go folks arming the system gummy bears are go 153 00:15:22,900 --> 00:15:24,900 I 154 00:15:26,340 --> 00:15:31,260 Watching in three two one 155 00:15:34,060 --> 00:15:38,340 See smoke.

We're not gonna give up just yet. We're gonna fire the hard candy rocket one more time 196 00:18:55,840 --> 00:19:03,840 I'm gonna add a sous-saint of, shall we say, encouragement to help it go a little more vigorously. 197 00:19:03,840 --> 00:19:08,840 What I'm doing is I put a spray adhesive down the throat of this and then pour gunpowder on it, 198 00:19:08,840 --> 00:19:10,840 and it coats the inside of the rocket engine. 199 00:19:10,840 --> 00:19:15,840 So when we stick the igniter in there, the whole surface is ignited nicely. 200 00:19:15,840 --> 00:19:17,840 This should be good to go. 201 00:19:17,840 --> 00:19:22,840 So with an even sprinkling of black powder in place to help initiate ignition, 202 00:19:22,840 --> 00:19:26,840 the guys are shooting for one last shot at gummy glory. 203 00:19:26,840 --> 00:19:31,840 So we've tried all our different versions of gummy bears and nothing has worked yet. 204 00:19:31,840 --> 00:19:35,840 This one right here has got to work. It's now or never. 205 00:19:35,840 --> 00:19:37,840 Alright, Mr. Heidemann, are you ready? 206 00:19:37,840 --> 00:19:38,840 I'm ready. 207 00:19:38,840 --> 00:19:39,840 Here we go. 208 00:19:39,840 --> 00:19:42,840 Here we are launching the hard candy rocket. 209 00:19:42,840 --> 00:19:47,840 Three, two, one, launch. 210 00:19:47,840 --> 00:19:49,840 Yep, come on, baby. 211 00:19:50,840 --> 00:19:54,840 Come on! It's got to go! 212 00:19:59,840 --> 00:20:04,840 It was the best-case candy scenario and there was no lift-off. 213 00:20:04,840 --> 00:20:09,840 But has the myth been busted or the mythbusters methodology? 214 00:20:09,840 --> 00:20:10,840 What is wrong? 215 00:20:10,840 --> 00:20:13,840 The Heidemann smells a hardware rat. 216 00:20:13,840 --> 00:20:18,840 At this point I'm becoming suspicious as to whether it's the fuel's fault 217 00:20:18,840 --> 00:20:23,840 or is it, say, the oxidizer or the general rocket system that is at fault here. 218 00:20:23,840 --> 00:20:27,840 So this next attempt, we're going to try and eliminate that as a concern 219 00:20:27,840 --> 00:20:30,840 and we're going to use paraffin as the fuel, 220 00:20:30,840 --> 00:20:34,840 which we know is capable of making a rocket like this fly really far. 221 00:20:34,840 --> 00:20:38,840 Yep, by replacing the gummy bears with standard rocket fuel, 222 00:20:38,840 --> 00:20:42,840 this control launch will test the hardware itself. 223 00:20:43,840 --> 00:20:49,840 Packed with paraffin, the rocket experts expect an altitude of 20,000 feet. 224 00:20:49,840 --> 00:20:53,840 Anything less than that, we're going to have some problems to solve. 225 00:20:54,840 --> 00:21:01,840 Okay, here we go. Launching in three, two, one. 226 00:21:02,840 --> 00:21:04,840 That's it, I see smoke. 227 00:21:04,840 --> 00:21:06,840 No! 228 00:21:11,840 --> 00:21:12,840 Ah! 229 00:21:12,840 --> 00:21:16,840 That's clearly not the high altitude expected. 230 00:21:16,840 --> 00:21:21,840 Here it comes. That doesn't look like it went higher than about 6 or 700 feet. 231 00:21:23,840 --> 00:21:26,840 It should have got at least 30 times higher. 232 00:21:26,840 --> 00:21:29,840 After the failure of all of our gummy bear rockets, 233 00:21:29,840 --> 00:21:33,840 we fired off this paraffin rocket as a test of our hardware and technology 234 00:21:33,840 --> 00:21:39,840 and it flew 675 feet. That is unremarkable. 235 00:21:40,840 --> 00:21:46,840 That is a pretty clear marker that we need to review our hardware and our technology before proceeding. 236 00:21:48,840 --> 00:21:50,840 Well, the rockets just aren't working. 237 00:21:50,840 --> 00:21:53,840 No, and the gummy bear results have to be thrown out completely. 238 00:21:53,840 --> 00:21:56,840 It's the tricky finicky business of these hybrid rockets 239 00:21:56,840 --> 00:21:58,840 that's getting in the way of us getting any actual results. 240 00:21:58,840 --> 00:22:00,840 I don't know what we're going to do. 241 00:22:00,840 --> 00:22:03,840 Well, let's head back to the shop and regroup. 242 00:22:03,840 --> 00:22:05,840 Alright, we'll have a total rethink about this. 243 00:22:05,840 --> 00:22:06,840 Yeah. 244 00:22:06,840 --> 00:22:10,840 With the hardware fail, all their results are redundant. 245 00:22:10,840 --> 00:22:16,840 All they've proved so far is they're facing one of the most challenging experiments in Mythbusters history. 246 00:22:17,840 --> 00:22:20,840 So it's back to the shop and square one. 247 00:22:21,840 --> 00:22:24,840 So these are the parts we were trying to use in the desert. 248 00:22:24,840 --> 00:22:29,840 We've got your gummy bears here, we've got your oxidizer, pressurized tank here with the valves 249 00:22:29,840 --> 00:22:31,840 and touch the ignition systems. 250 00:22:31,840 --> 00:22:33,840 Look, I think we just bit off more than we can chew. 251 00:22:33,840 --> 00:22:35,840 We are moving on. 252 00:22:35,840 --> 00:22:37,840 Instead, we're going to use a solid rocket motor like this. 253 00:22:37,840 --> 00:22:45,840 It may not look like that much, but it's actually a very carefully prepared mixture of fuel, oxidizer, and a binder to hold it all together. 254 00:22:45,840 --> 00:22:49,840 Now, it's nice and simple because in theory, all you do is light it and off it goes. 255 00:22:49,840 --> 00:22:55,840 We're going to make our own version of it using gummy bears as fuel along with the same oxidizer and binder. 256 00:22:56,840 --> 00:23:05,840 Solid rockets. They've ejected Buster's bond seed, powered Jato, and fired the Huacha. They're simple and effective. 257 00:23:05,840 --> 00:23:13,840 But producing fuel grains like this is not only time consuming and difficult, but you need a special license which neither Jamie nor I possess. 258 00:23:13,840 --> 00:23:18,840 So what we're going to do here is to turn these gummies into a powder. 259 00:23:18,840 --> 00:23:19,840 Here we go. 260 00:23:19,840 --> 00:23:24,840 And then send them off to a specialist who will produce for us fuel grains that look like this. 261 00:23:25,840 --> 00:23:29,840 This specialist require the fuel as a fine dry powder. 262 00:23:29,840 --> 00:23:33,840 Three, two, one. 263 00:23:33,840 --> 00:23:42,840 And to convert the gummies, Adam has hit upon a technique that doesn't involve large quantities of lethal lava-like serum. 264 00:23:42,840 --> 00:23:46,840 It seems like it's working strategically. 265 00:23:46,840 --> 00:23:52,840 Okay, I'm going to use a coffee grinder to make them even more powdery. 266 00:23:52,840 --> 00:23:54,840 Dude, look at that. 267 00:23:54,840 --> 00:23:58,840 That is a super fine powder that used to be gummy bears. 268 00:23:58,840 --> 00:24:02,840 That's exactly what our rocketeers want. 269 00:24:02,840 --> 00:24:05,840 Time to make a whole bunch more. 270 00:24:05,840 --> 00:24:12,840 While Adam ramps up production on his gummy bear crystal method, Jamie is well-being Jamie. 271 00:24:12,840 --> 00:24:16,840 Look, I'm loving the technical challenge of making a gummy bear-powered rocket. 272 00:24:16,840 --> 00:24:18,840 And if it works, cool. 273 00:24:18,840 --> 00:24:22,840 But let's face it, ultimately, there's no real practical application for it. 274 00:24:22,840 --> 00:24:28,840 So I'm going to make a second fuel powder, one that could conceivably be useful. 275 00:24:28,840 --> 00:24:31,840 Oh, God. 276 00:24:31,840 --> 00:24:34,840 That's awful. 277 00:24:34,840 --> 00:24:36,840 I'm going to use poop. 278 00:24:36,840 --> 00:24:42,840 It's a pretty disgusting sequence up next, so you might want to put down your snacks. 279 00:24:42,840 --> 00:24:46,840 Yep, Jamie's moving on from the myth and is thinking ahead. 280 00:24:46,840 --> 00:24:49,840 He's looking into the future of space travel. 281 00:24:49,840 --> 00:24:51,840 No, really? 282 00:24:51,840 --> 00:24:53,840 Oh, man, that's nasty. 283 00:24:53,840 --> 00:24:58,840 Add like Adam, his first step is to turn his potential fuel into a dry powder. 284 00:24:58,840 --> 00:25:04,840 First, I'm going to dry it out up here in the sun, which has the added benefit of keeping the stink out of the shop. 285 00:25:04,840 --> 00:25:07,840 They're already giving me night bears. 286 00:25:07,840 --> 00:25:11,840 And then I'm going to grind it down into a fine dry powder. 287 00:25:11,840 --> 00:25:15,840 Some sun-dried poop coming right up. 288 00:25:15,840 --> 00:25:17,840 I want them nice and dry and crispy. 289 00:25:17,840 --> 00:25:20,840 That's the way I like them. 290 00:25:21,840 --> 00:25:24,840 Ha ha ha ha ha ha. 291 00:25:24,840 --> 00:25:29,840 Processing dog waste into powder is one thing, but the big question is why. 292 00:25:29,840 --> 00:25:34,840 Look, I know it sounds kind of crazy, but crazy is kind of Jamie's MO. 293 00:25:34,840 --> 00:25:39,840 I have no idea if this is going to work or not, but we'll soon find out. 294 00:25:39,840 --> 00:25:43,840 Whenever he can design a system that has no waste whatsoever, 295 00:25:43,840 --> 00:25:49,840 where he's expended just enough energy to get the job done and no more, he is the happiest. 296 00:25:49,840 --> 00:25:52,840 Well, it's definitely breaking it up. 297 00:25:52,840 --> 00:25:56,840 And where does that philosophy reach?

It's tripping a lot. 379 00:30:52,840 --> 00:31:01,840 Proving once again that rocket science is, well, rocket science, wind conditions were less than ideal. 380 00:31:01,840 --> 00:31:06,840 Alright, let's go get our rocket. 381 00:31:06,840 --> 00:31:10,840 During ascent, the rocket was pushed significantly sideways. 382 00:31:10,840 --> 00:31:14,840 We might be wanting to drink here for a little while. 383 00:31:14,840 --> 00:31:23,840 But after a successful search and rescue, they head back to base, where they discover it reached 4,133 feet. 384 00:31:23,840 --> 00:31:27,840 But more detailed data reveals a potential problem. 385 00:31:27,840 --> 00:31:35,840 So we had a good launch, but the telemetry in GPS is telling us that we had a lot of lateral drift that may have compromised our data. 386 00:31:35,840 --> 00:31:41,840 Because if that curve was straightened out, it might have actually given us a higher altitude. 387 00:31:41,840 --> 00:31:44,840 So we've got another one of these rockets. 388 00:31:44,840 --> 00:31:46,840 Control test number two. 389 00:31:46,840 --> 00:31:48,840 And we're going to go again just to be sure. 390 00:31:48,840 --> 00:31:54,840 Yep, to ensure all the launches have equal conditions, they wait until the wind dies down. 391 00:31:54,840 --> 00:31:56,840 Alright, let's do this. You ready? 392 00:31:56,840 --> 00:31:57,840 Yeah. 393 00:31:57,840 --> 00:32:05,840 This is control number two, firing in three, two, one, launch. 394 00:32:11,840 --> 00:32:13,840 Wow. 395 00:32:13,840 --> 00:32:17,840 Beauty! 396 00:32:17,840 --> 00:32:19,840 That one went straight up. 397 00:32:19,840 --> 00:32:25,840 Straight up, almost straight down. 398 00:32:25,840 --> 00:32:28,840 Dude, I think that one's going to land like right here. 399 00:32:28,840 --> 00:32:34,840 It was coming right down, right on top of us. 400 00:32:34,840 --> 00:32:37,840 Nice walking distance from the bunker. 401 00:32:37,840 --> 00:32:42,840 And telemetry says the distance this went to was 4,491 feet. 402 00:32:42,840 --> 00:32:46,840 Well, that gives us our baseline. Time to fire up the gummy bear rocket. 403 00:32:46,840 --> 00:32:49,840 Let's do it. 404 00:32:49,840 --> 00:32:54,840 Unaffected by wind, control number two went almost 400 feet high. 405 00:32:54,840 --> 00:33:02,840 And the benchmark for gummy bears has been established. 406 00:33:02,840 --> 00:33:07,840 The rocket propellant we've been using is 77% ammonium perchlorate oxidizer 407 00:33:07,840 --> 00:33:11,840 and 23% fuel mixed with a rubber binder. 408 00:33:11,840 --> 00:33:17,840 Now we're replacing that fuel component with gummy bear powder. 409 00:33:17,840 --> 00:33:19,840 In goes the gummy bear motor. 410 00:33:19,840 --> 00:33:27,840 What we're looking to find out is how the gummy bear fuel component compares to the conventional fuel component. 411 00:33:27,840 --> 00:33:31,840 Good to go. 412 00:33:32,840 --> 00:33:37,840 It's been one of the most technically challenging experiments in Mythbusters history. 413 00:33:37,840 --> 00:33:41,840 But this is it. The gummy bears are good to go. 414 00:33:41,840 --> 00:33:46,840 You know, Jamie, not many people know this, but gummy bears are actually the poop of baby unicorns. 415 00:33:46,840 --> 00:33:47,840 Really? 416 00:33:47,840 --> 00:33:51,840 Yeah. No one's ever gotten close enough to figure out how their sphincter makes that bear shape. 417 00:33:51,840 --> 00:33:55,840 But a little known fact. 418 00:33:55,840 --> 00:34:02,840 The key point of comparison for the energy and efficiency of the propellant will be the maximum altitude attained. 419 00:34:02,840 --> 00:34:04,840 Alright, so this is it.
