It's actually collapsible, so I guess it fits in your bag well. 76 00:04:11,000 --> 00:04:17,000 And you set it up like this, you thread it down, and there, it's ready to go. 77 00:04:17,000 --> 00:04:25,000 The Betel Tactical Air Initiated Launch System, Tails for short, was developed for the U.S. Navy to aid ship-to-ship rescue. 78 00:04:26,000 --> 00:04:28,000 It's a little bigger than Batman's. 79 00:04:28,000 --> 00:04:35,000 It has a tank, it's got a piston, and it just lets the piston go and it shoots the grappling hook. 80 00:04:35,000 --> 00:04:37,000 It'll go a hundred feet straight up. 81 00:04:37,000 --> 00:04:42,000 And that's a prospect that's got Jamie cackling like a super villain. 82 00:04:43,000 --> 00:04:48,000 Before they crawl the wall, they rig a safety system. 83 00:04:49,000 --> 00:04:51,000 This setup right here is our safety backup. 84 00:04:51,000 --> 00:04:59,000 This is a belay system, and so if there's anything that goes wrong with the grappling hook, this will kick in and keep one of us from falling and hitting the ground. 85 00:04:59,000 --> 00:05:04,000 Jess will be on the ground paying out rope as one of us tries to climb up. 86 00:05:04,000 --> 00:05:07,000 So if that person slips, Jess will catch them. 87 00:05:07,000 --> 00:05:09,000 Jess will catch them. 88 00:05:09,000 --> 00:05:11,000 That's the theory. 89 00:05:11,000 --> 00:05:17,000 So will these regular grappling hooks enable Adam and Jamie to walk the wall like the Cape Crusader? 90 00:05:17,000 --> 00:05:21,000 You know, I'm not in really great shape like Batman is, but you know, we're going to try. 91 00:05:24,000 --> 00:05:27,000 Oh, I caught a big one. Look at that. 92 00:05:27,000 --> 00:05:30,000 Not to feed my family for a month. 93 00:05:30,000 --> 00:05:36,000 While Adam struggles with the mojo of the throw, Jamie's off like a shot. 94 00:05:36,000 --> 00:05:39,000 Three, two, one. 95 00:05:43,000 --> 00:05:46,000 You cleared the whole building, Jamie. Nice work. 96 00:05:50,000 --> 00:05:53,000 Finally, Adam's grappling hook also grabs hold. 97 00:05:53,000 --> 00:05:54,000 Is that purchase? 98 00:05:54,000 --> 00:05:55,000 You've got purchase. 99 00:05:55,000 --> 00:05:58,000 So that just leaves the climbing. 100 00:05:58,000 --> 00:05:59,000 You all said Batman? 101 00:05:59,000 --> 00:06:01,000 I'm all set, boy wonder. 102 00:06:01,000 --> 00:06:04,000 Adam attacks the wall head on. 103 00:06:07,000 --> 00:06:10,000 There's no, this is not going to happen at all. 104 00:06:10,000 --> 00:06:13,000 Don't remember Batman having this much trouble. 105 00:06:13,000 --> 00:06:20,000 With Adam floundering like a fish out of water, Jamie's decided to try a different climbing technique. 106 00:06:20,000 --> 00:06:23,000 What I'm tying here is known as a Prusik knot. 107 00:06:23,000 --> 00:06:25,000 Basically, it's a one-way knot. 108 00:06:25,000 --> 00:06:30,000 When you push on it, it slides up, but when you bear down on it, it won't go the other way. 109 00:06:30,000 --> 00:06:35,000 Thanks to his knots, Jamie soon up, up. 110 00:06:35,000 --> 00:06:38,000 And away. 111 00:06:38,000 --> 00:06:42,000 Oh yeah, he's cruising now. 112 00:06:42,000 --> 00:06:46,000 Ladies and gentlemen, there's a new superhero on the block. 113 00:06:46,000 --> 00:06:53,000 Jamie Heineman is the inchworm, able to leave tall buildings given plenty of notice. 114 00:06:53,000 --> 00:06:56,000 But at least he's gaining altitude. 115 00:06:56,000 --> 00:07:07,000 His fellow heroes not scaling, he's absailing. 116 00:07:17,000 --> 00:07:20,000 You guys don't mind, I'm just going to lie here for a while. 117 00:07:20,000 --> 00:07:25,000 Jamie eventually makes it to the top. 118 00:07:25,000 --> 00:07:27,000 But not at a great rate of knots. 119 00:07:27,000 --> 00:07:33,000 My little knot trick worked, but it took me probably just under 10 minutes to make it up this 20-foot wall. 120 00:07:33,000 --> 00:07:38,000 And if you're a superhero trying to save the little old lady, you need to do it quicker than that. 121 00:07:38,000 --> 00:07:44,000 While both grappling hooks held firm, it was the boys' ascent that failed. 122 00:07:44,000 --> 00:07:50,000 To get this myth off the ground, they're going to need to build something that can take the climb out of the equation. 123 00:07:50,000 --> 00:07:52,000 Superhero style. 124 00:07:53,000 --> 00:07:56,000 I think we need to go back to the shop and build our own solution. 125 00:07:56,000 --> 00:07:58,000 Okay, let's go. 126 00:07:58,000 --> 00:08:00,000 Coming up on Mythbusters. 127 00:08:00,000 --> 00:08:03,000 We put superhero myths to the test. 128 00:08:03,000 --> 00:08:05,000 Next, it's a phantom favorite. 129 00:08:05,000 --> 00:08:09,000 Can a powerhouse punch really leave the baddie grandest? 130 00:08:09,000 --> 00:08:11,000 Oh! 131 00:08:16,000 --> 00:08:19,000 It's the Mythbusters superhero special. 132 00:08:19,000 --> 00:08:23,000 And superheroes big and small are getting put to the test. 133 00:08:23,000 --> 00:08:28,000 And next up, a superhero myth with a very familiar ring. 134 00:08:28,000 --> 00:08:30,000 Are you ready for a fun, violent myth? 135 00:08:30,000 --> 00:08:32,000 It involves punches. 136 00:08:32,000 --> 00:08:37,000 Sorry, another than the phantom. 137 00:08:37,000 --> 00:08:41,000 He's a superhero that left that nasty calling card on all of his evildoers. 138 00:08:41,000 --> 00:08:47,000 Yeah, you know, he's that guy that could punch people so hard that he'd leave a scar in the shape of a skull from his ring. 139 00:08:47,000 --> 00:08:52,000 The Plague's the Thing in this comic book classic. 140 00:08:52,000 --> 00:09:00,000 A superhero swings and adds imprint to injury by branding the baddie with an indelible ring scar. 141 00:09:00,000 --> 00:09:04,000 But is that possible even for a superhero? 142 00:09:05,000 --> 00:09:07,000 So how are we going to do this one? 143 00:09:07,000 --> 00:09:15,000 Well, Carrie, I really don't think we should test this on each other because personally, I don't want to risk a permanent scar on my face. 144 00:09:15,000 --> 00:09:17,000 We can't punch each other, who are we going to punch? 145 00:09:17,000 --> 00:09:21,000 Well, it sounds like we're going to need a human analog, so it looks like it's pig time. 146 00:09:21,000 --> 00:09:28,000 Perfect. I think we should use human force as a control and then I'll build a machine to punch with the force of a heavyweight prize fighter. 147 00:09:28,000 --> 00:09:32,000 That's good. That'll give us the maximum strength that a person can punch with. 148 00:09:32,000 --> 00:09:34,000 And if that doesn't work, we'll go superhuman. 149 00:09:34,000 --> 00:09:40,000 You deal with the pig and you build the robot. That means I get to build a Mythbuster Phantom Skull Ring. 150 00:09:40,000 --> 00:09:50,000 The guys won't be pulling any punches. They'll make a fake fist complete with Skull Ring and attach it to an air-powered punching rig. 151 00:09:50,000 --> 00:09:54,000 The rig has to hit like a human, so Grant sets up the force plate. 152 00:09:54,000 --> 00:10:01,000 We're going to see what we can punch. Then we're going to calibrate our robot to punch the same amount and we'll see what we get. 153 00:10:03,000 --> 00:10:05,000 Soon the fists are flying. 154 00:10:07,000 --> 00:10:16,000 But none of these guys have super strength. The best of the three was Tories, which peaked at a rather feeble 1,750 newtons. 155 00:10:16,000 --> 00:10:23,000 But our research says that the upper range, which is a heavyweight boxer, is about 4,000 newtons. 156 00:10:23,000 --> 00:10:24,000 Why? 157 00:10:24,000 --> 00:10:26,000 We're not even close. 158 00:10:27,000 --> 00:10:36,000 As we know, Grant was raised by robots. And given that special affinity, he soon got a punching machine ready to swing. 159 00:10:36,000 --> 00:10:44,000 Okay, so this is our superhero punching rig. Our air cylinder is right here and the fist goes on to the end of this. 160 00:10:44,000 --> 00:10:51,000 And when we're ready, you go... and that gives you a punch. 161 00:10:51,000 --> 00:10:55,000 Tories making a good fist of the making a fist. 162 00:10:55,000 --> 00:11:03,000 What I'm doing right now is I'm casting my hand in a fist shape because we're going to be needing to punch a bunch of times at superhero strikes. 163 00:11:03,000 --> 00:11:08,000 And we want a hand that's not going to break like mine may have. 164 00:11:08,000 --> 00:11:18,000 That's the theory. And by using a combination of ballistics gel and urethane hardener, Tories should get a fist that can roll with the punches. 165 00:11:18,000 --> 00:11:27,000 Alright, so this looks great. It's really, really hard, but it's still rubber, so it shouldn't shatter when we start punching with superhero strength. 166 00:11:27,000 --> 00:11:33,000 Meanwhile, Carrie's designed some superhero style rings and carved them in wax. 167 00:11:33,000 --> 00:11:40,000 To keep with the Phantom theme, I've got a skull. Also incorporated the MB for myth busters to make it a little bit more ours. 168 00:11:40,000 --> 00:11:45,000 Next step is to take all of these rings that I've carved down to the crucible, get them cast up in metal. 169 00:11:45,000 --> 00:11:50,000 I need these two in adamantium and these two in kryptonite. 170 00:11:50,000 --> 00:11:53,000 We don't have either of those, but we do have sterling silver. 171 00:11:53,000 --> 00:11:55,000 Sterling silver will do nice. 172 00:11:55,000 --> 00:12:00,000 Faster than a speeding bullet, Carrie's rings are ready. 173 00:12:00,000 --> 00:12:02,000 Primrose beware the mark of the myth buster. 174 00:12:02,000 --> 00:12:06,000 Whoa, cool!

I think we're going to have to build this device ourselves. 226 00:15:36,000 --> 00:15:43,000 Yeah, but it seems to me that there are actually two distinct elements to this cable gun winch thing. 227 00:15:43,000 --> 00:15:44,000 Okay, what are they? 228 00:15:44,000 --> 00:15:47,000 Well, you've got the winch, and you've got the gun. 229 00:15:47,000 --> 00:15:51,000 So why don't we treat them separately? One of us build one, and one build the other. 230 00:15:51,000 --> 00:15:58,000 So why don't you take the mechanical ascending rig, and I'll take the gun that fires the thing into the wall that sticks in the wall. 231 00:15:58,000 --> 00:15:59,000 Okay. 232 00:15:59,000 --> 00:16:02,000 And then we'll finish off with the final climb off. 233 00:16:02,000 --> 00:16:03,000 Great. 234 00:16:03,000 --> 00:16:04,000 Alright. 235 00:16:04,000 --> 00:16:07,000 Our superheroes go head to head. 236 00:16:07,000 --> 00:16:13,000 Jamie's task is to build a super lightweight winch to ascend buildings at the push of a button. 237 00:16:14,000 --> 00:16:19,000 Adam's making a device that can shoot a cable into a concrete wall. 238 00:16:20,000 --> 00:16:22,000 I got the nail in there. Look at that. 239 00:16:22,000 --> 00:16:30,000 There's just one rule. Both gadgets have to be as small as possible so they can fit on a superhero's belt. 240 00:16:31,000 --> 00:16:38,000 The challenge in this particular case is how small can we get it? It's got to be really powerful and really small. 241 00:16:38,000 --> 00:16:43,000 Jamie's device straps to his forearm and is powered by a battery on his belt. 242 00:16:43,000 --> 00:16:55,000 The motor is the smallest and fastest he could find. It puts out 30,000 RPM, but by itself it's not powerful enough to hoist high-temin up a high-rise. 243 00:16:55,000 --> 00:17:01,000 These gear reductions actually translate the power that this engine puts out into something I can use. 244 00:17:01,000 --> 00:17:06,000 Instead of 30,000 RPM, they're reducing the speed and increasing the torque. 245 00:17:06,000 --> 00:17:12,000 So I end up with something that is 750 RPM, but very powerful. 246 00:17:12,000 --> 00:17:19,000 It sure got a flashy superhero feel, but will it work? Jamie's going to test it on his sidekick. 247 00:17:19,000 --> 00:17:25,000 What I'm going to do instead of trying to pull myself up is actually pull Jess along the floor. 248 00:17:25,000 --> 00:17:28,000 She's going to go skiing in the shop. 249 00:17:28,000 --> 00:17:30,000 Alright, Jamie, I'm ready. 250 00:17:30,000 --> 00:17:35,000 Does Jamie's rig have the pulling power to make Jess do the shop floor shimmy? 251 00:17:43,000 --> 00:17:44,000 It worked. 252 00:17:44,000 --> 00:17:48,000 It worked. Looks like superhero gadget number one is ready to roll. 253 00:17:48,000 --> 00:17:57,000 Meanwhile, on the other side of the myth cave, Adam's getting the drop on his cable-firing device. 254 00:17:58,000 --> 00:18:00,000 Sorry. 255 00:18:00,000 --> 00:18:04,000 The centerpiece of his design is a .22 caliber nail gun. 256 00:18:04,000 --> 00:18:14,000 It takes a rim-fire .22 caliber shell here, sticks in there, put your nail on the tip, bring it up to it, bang, hit it, crack. 257 00:18:14,000 --> 00:18:19,000 .22 caliber shell fires a nail right into the concrete. 258 00:18:19,000 --> 00:18:26,000 His cutting plan, attach the cable to the nail gun, then fire that from a diver's spear gun. 259 00:18:26,000 --> 00:18:33,000 When the nail gun hits the wall, the blank rim fires the nail into the concrete and the cable's ready to cross. 260 00:18:33,000 --> 00:18:34,000 Like this. 261 00:18:34,000 --> 00:18:38,000 In three, two, one. 262 00:18:38,000 --> 00:18:41,000 Oh, well, sorta. 263 00:18:41,000 --> 00:18:43,000 Batman probably didn't get it on his first try either. 264 00:18:43,000 --> 00:18:44,000 No. 265 00:18:44,000 --> 00:18:46,000 So, you know, it's going to take time. 266 00:18:46,000 --> 00:18:48,000 Three, two, one. 267 00:18:48,000 --> 00:18:49,000 Oh. 268 00:18:49,000 --> 00:18:52,000 Shoot, you got to work out that hitting the wall part. 269 00:18:53,000 --> 00:18:58,000 The scene is set for a superhero grappling gadget showdown. 270 00:18:58,000 --> 00:18:59,000 You all set with that thing?

319 00:21:10,000 --> 00:21:12,000 Yeah, let's go. 320 00:21:14,000 --> 00:21:24,000 Coming next, The MythMobile gets a makeover with Loose Cannon's Carrie Grant and Torry. 321 00:21:24,000 --> 00:21:28,000 That's the first time that I've ever felt that much danger. 322 00:21:31,000 --> 00:21:34,000 Please, don't try anything that you're about to see us do at home. 323 00:21:34,000 --> 00:21:36,000 Ever. 324 00:21:37,000 --> 00:21:45,000 We're flying high in a superhero special, and The Next Myth combines cars and comic book craziness. 325 00:21:45,000 --> 00:21:48,000 Next up, Batmobile 90 degree tour. 326 00:21:48,000 --> 00:22:01,000 Batman, to get away from the bad guys, screaming down the street, and to escape, all he has to do is push a button that deploys a grappling hook, grabs onto his steel structure, and it whirls him around the corner, and the crooks can't get him. 327 00:22:01,000 --> 00:22:03,000 Dude, that sounds awesome. 328 00:22:04,000 --> 00:22:08,000 Holy awesome, this Grant Man. Let's see how this myth works. 329 00:22:08,000 --> 00:22:22,000 During our comic strip car chase, our hero hits a button, and a grappling hook fires from the car, wraps itself around a steel structure, and swings our superheroes through a high speed 90 degree turn to safety. 330 00:22:22,000 --> 00:22:25,000 We have to build a cannon capable of firing a grappling hook. 331 00:22:25,000 --> 00:22:32,000 A grappling hook strong enough to hold the force of a car, and if all that works, hope that the structure doesn't crumble. 332 00:22:33,000 --> 00:22:45,000 Here's the plan. The guys will mount an air powered cannon in a car, fire a grappling hook at speed, and see if the cable can swing the car around a right angle bend. 333 00:22:45,000 --> 00:22:49,000 First things first though, this myth needs wheels. 334 00:22:49,000 --> 00:22:53,000 Obviously we're going to need a car for all this, and I have the perfect one in mind. 335 00:22:53,000 --> 00:22:57,000 Jamie and Adam just did a night rider myth, and they have a car just rusting out in the parking lot. 336 00:22:57,000 --> 00:22:59,000 The Mythmobile. 337 00:22:59,000 --> 00:23:01,000 Did you just come up with that? 338 00:23:01,000 --> 00:23:03,000 Yeah. 339 00:23:03,000 --> 00:23:21,000 The Joker aside, this car is perfect for this myth, because it's already been fitted with a roll cage and safety harnesses, which means all Carrie and Tori have to do is transform the transport into something more befitting a superhero. 340 00:23:21,000 --> 00:23:26,000 This is going to be the coolest Batmobile ever. 341 00:23:26,000 --> 00:23:32,000 Meanwhile, Grant's finding out more about the serious physics facing them in this myth. 342 00:23:32,000 --> 00:23:40,000 One thing we have to consider with this myth is that we're going from a straight path once we hook onto that structure into a circular one. 343 00:23:40,000 --> 00:23:51,000 Now, this induces a force that points inwards towards the center called centripetal force, and you can calculate that based on the weight of the car, the distance from the center, and the speed that you're going. 344 00:23:51,000 --> 00:23:59,000 I've run the numbers, and we should be experiencing about 7,000 pounds, and that's going to be the tension on the cable. 345 00:23:59,000 --> 00:24:05,000 So we're going to select our cable to be more than adequate to handle that amount of force. 346 00:24:07,000 --> 00:24:15,000 Will the mythmobile be able to cope with that kind of hardcore cornering? One thing it can turn is heads. 347 00:24:15,000 --> 00:24:17,000 What do you think of the car? 348 00:24:17,000 --> 00:24:19,000 Cool. 349 00:24:19,000 --> 00:24:22,000 The cable is ready at stage one. 350 00:24:22,000 --> 00:24:25,000 Stage two, they need a grappling hook. 351 00:24:28,000 --> 00:24:32,000 I want to keep going. I think if we use a solid steel grappling hook, that might work. 352 00:24:32,000 --> 00:24:40,000 Well, I've got an idea for an air cannon to launch the grappling hook, but if you're going to use solid steel, we're going to have to make it a lot more powerful. 353 00:24:40,000 --> 00:24:45,000 And I have the answer. I'm going to use nitrogen, which will give us up to 3,000 psi of working pressure. 354 00:24:45,000 --> 00:24:46,000 Oh my God. 355 00:24:46,000 --> 00:24:48,000 Dude, that sounds super hero-y. 356 00:24:48,000 --> 00:24:59,000 3,000 psi? To put that into perspective, Grant's cannon will be 60 times more powerful than Adam and Jamie's famous chicken gun. 357 00:24:59,000 --> 00:25:00,000 Woo! 358 00:25:00,000 --> 00:25:06,000 But because it has to fit into a superhero's car, it'll be much more compact. 359 00:25:06,000 --> 00:25:08,000 Holy air cannon, Grant man. 360 00:25:10,000 --> 00:25:12,000 How long have you been waiting to unleash that? 361 00:25:12,000 --> 00:25:13,000 All day. 362 00:25:13,000 --> 00:25:14,000 All day. 363 00:25:14,000 --> 00:25:15,000 I've been waiting for that one. 364 00:25:15,000 --> 00:25:21,000 You know, this is actually the most dangerous thing I've built in the long line of dangerous things. 365 00:25:24,000 --> 00:25:30,000 Tari's bending steel likes Superman, except Superman doesn't have to heat his up first. 366 00:25:30,000 --> 00:25:34,000 All right, so the grappling hook is done. We weighed it. It weighs 10 and a half pounds. 367 00:25:34,000 --> 00:25:37,000 Now we're going to put it in the air cannon and see how far it goes. 368 00:25:38,000 --> 00:25:47,000 This time the cannon's at two-thirds power. Will that be enough to send 10 pounds of solid steel through the air and comic book style? 369 00:25:48,000 --> 00:25:49,000 All right, you ready? 370 00:25:49,000 --> 00:25:51,000 Oh, so ready. 371 00:25:51,000 --> 00:25:53,000 2200 real hook. 372 00:25:55,000 --> 00:25:58,000 In three, two, one. 373 00:25:59,000 --> 00:26:01,000 Oh my God! 374 00:26:03,000 --> 00:26:07,000 The cannon launched the hook all right. It also launched itself clean off the table. 375 00:26:08,000 --> 00:26:09,000 Where's the camera? 376 00:26:09,000 --> 00:26:11,000 Where's the high speed camera? 377 00:26:11,000 --> 00:26:14,000 The phrase, loose cannon comes to mind. 378 00:26:14,000 --> 00:26:18,000 You know what? We didn't take into consideration the mass of the hook. 379 00:26:18,000 --> 00:26:20,000 Oh, Newton's Laws. 380 00:26:20,000 --> 00:26:21,000 Whoa, man. 381 00:26:21,000 --> 00:26:23,000 We forgot the Newton's Laws. 382 00:26:23,000 --> 00:26:29,000 Oh, you mean the one that says for every action there's an equal and opposite reaction? 383 00:26:32,000 --> 00:26:39,000 You know, we've done a lot of experiments on the show. Things have gone wrong, but that's the first time that I've ever felt that much danger. 384 00:26:39,000 --> 00:26:42,000 So for test two, they lock the cannon in place. 385 00:26:42,000 --> 00:26:46,000 In three, two, one. 386 00:26:48,000 --> 00:26:50,000 And get a perfect result. 387 00:26:50,000 --> 00:26:52,000 Wow, nice. 388 00:26:52,000 --> 00:26:55,000 The grappling hook flew straight as an arrow. 389 00:26:55,000 --> 00:26:57,000 So bring on the Mythmobile. 390 00:26:57,000 --> 00:27:05,000 Stay tuned, superhero fans, to see if the Mythmobile can make that corner in true superhero style. 391 00:27:05,000 --> 00:27:09,000 But next, it's up, up and away. 392 00:27:09,000 --> 00:27:11,000 Super grappling gadgets are gold. 393 00:27:11,000 --> 00:27:13,000 Who says superheroes don't bleed? 394 00:27:18,000 --> 00:27:21,000 It's the Mythbusters superhero special. 395 00:27:22,000 --> 00:27:27,000 If you're a cake-clad hero, it's not good for the image to be seen taking the elevator. 396 00:27:27,000 --> 00:27:34,000 You get much more cred if you fire your trusty grappling hook and quickly ascend to the city skyline. 397 00:27:34,000 --> 00:27:42,000 Adam and Jamie have devised their own miniature superhero-style grappling devices and are looking for the same uplifting experience. 398 00:27:42,000 --> 00:27:46,000 Perfect.
