177 00:09:49,560 --> 00:09:53,560 Here's another popular misconception is that methane gas is what creates the odor. 178 00:09:53,560 --> 00:09:59,560 It's the sulfur that's created inside you, which I have to say Adam has quite a bit of. 179 00:10:00,560 --> 00:10:02,560 It's so smelly. 180 00:10:05,560 --> 00:10:10,560 Jamie and Adam are the proud new owners of a 1967 Fury, 181 00:10:10,560 --> 00:10:15,560 the same model car featured in the myth of the driveshaft pole vault. 182 00:10:15,560 --> 00:10:21,560 After weakening the Fury's driveshaft, they need to find a way to break it on cue. 183 00:10:21,560 --> 00:10:24,560 And Jamie's got an idea. 184 00:10:24,560 --> 00:10:28,560 At high speed he's going to throw the gear into neutral, 185 00:10:28,560 --> 00:10:31,560 rev the engine, then jam it back into drive. 186 00:10:31,560 --> 00:10:36,560 The high rev should snap the weakened U-joint and drop the shaft on cue. 187 00:10:38,560 --> 00:10:40,560 And that's not all. 188 00:10:40,560 --> 00:10:43,560 They'll also be driving by remote control. 189 00:10:43,560 --> 00:10:46,560 Do it a little bit, see what it does. 190 00:10:46,560 --> 00:10:51,560 And Jamie and Adam have 4,000 pounds of V8 Fury to tame. 191 00:10:51,560 --> 00:10:56,560 And this one is by far the most advanced rig we've ever installed in a car. 192 00:10:56,560 --> 00:11:02,560 We're not only just controlling the throttle and the brake as we've done most other times, 193 00:11:02,560 --> 00:11:05,560 but we're also controlling the shifter. 194 00:11:05,560 --> 00:11:12,560 And we've got a brand new steering control using some very high-tech servo drivers for the motor. 195 00:11:12,560 --> 00:11:14,560 I can precisely control that. 196 00:11:14,560 --> 00:11:20,560 And that's right here is straight ahead and now we're turning to the right. 197 00:11:20,560 --> 00:11:22,560 So it works perfectly. 198 00:11:22,560 --> 00:11:29,560 Now that Jamie's got the steering under control, Adam's got the tricky task of figuring out the brakes. 199 00:11:29,560 --> 00:11:32,560 It doesn't matter how many times I build this circuit, I always need to draw it out. 200 00:11:32,560 --> 00:11:34,560 It's always really confusing. 201 00:11:34,560 --> 00:11:36,560 That's the brake, isn't that pretty? 202 00:11:38,560 --> 00:11:46,560 It's arguably the most critical part of the whole operation because you have to be able to stop the car. 203 00:11:46,560 --> 00:11:49,560 I mean, that's just critical. That's the emergency thing. 204 00:11:49,560 --> 00:11:56,560 The entire remote control system is set up so that if it fails, if it loses its signal, it automatically depresses the brake. 205 00:11:56,560 --> 00:12:02,560 The hardest part of the remote rig is calibrating four different control systems. 206 00:12:02,560 --> 00:12:06,560 Steering, throttle, brake, and throttle brake. 207 00:12:06,560 --> 00:12:10,560 We have a servo, a custom-made servo that's mounted to the steering wheel. 208 00:12:10,560 --> 00:12:15,560 We have another servo that is set up to shift. 209 00:12:15,560 --> 00:12:18,560 We can go forward, reverse, neutral. 210 00:12:18,560 --> 00:12:21,560 We have a third servo, which is on the throttle. 211 00:12:21,560 --> 00:12:27,560 And then lastly, we have an electronic piston that pushes on the brake on cueing. 212 00:12:27,560 --> 00:12:31,560 So it can put the brakes on or off or somewhere in between. 213 00:12:32,560 --> 00:12:35,560 The remote rig has got a big job to do. 214 00:12:35,560 --> 00:12:41,560 From a distance, we have to be able to, say, thread a needle with this car. 215 00:12:41,560 --> 00:12:43,560 Tell me when I'm straight. 216 00:12:43,560 --> 00:12:45,560 Okay, a little more, a little more, more, more, more. 217 00:12:45,560 --> 00:12:47,560 More. Perfect. 218 00:12:47,560 --> 00:12:51,560 Surviving this myth might be a victory in itself. 219 00:13:08,560 --> 00:13:16,560 The test site, an abandoned runway, is perfect for playing with two tons of high-powered Detroit steel. 220 00:13:16,560 --> 00:13:18,560 You couldn't ask for a better spot than this. 221 00:13:18,560 --> 00:13:21,560 We have a white line straight as an arrow. 222 00:13:21,560 --> 00:13:28,560 We've got, like, thousands of feet in all directions that we could lose control of the car without causing any damage. 223 00:13:28,560 --> 00:13:30,560 We should be good. 224 00:13:30,560 --> 00:13:33,560 It's a lovely day. We're going to have some fun. 225 00:13:41,560 --> 00:13:45,560 The only ones not having fun are the pothole diggers. 226 00:13:45,560 --> 00:13:51,560 But Tori wants to brighten up Scotty and Carrie's day with his two-wheeled tricks. 227 00:13:51,560 --> 00:13:54,560 Do you smell that? What's that? 228 00:13:54,560 --> 00:13:56,560 Bad things. 229 00:13:56,560 --> 00:13:58,560 Let's sag him on until he hurts himself. 230 00:13:58,560 --> 00:14:00,560 Yeah, it looks like you cleared it. Go for it. 231 00:14:00,560 --> 00:14:01,560 Does it? No. 232 00:14:01,560 --> 00:14:04,560 Scotty's wish is Tori's command. 233 00:14:04,560 --> 00:14:07,560 You wonder why you always see him getting hurt. 234 00:14:16,560 --> 00:14:19,560 Now, that's a pole vault. 235 00:14:19,560 --> 00:14:24,560 It's so disturbing, let's see it again in slow motion. 236 00:14:24,560 --> 00:14:27,560 But kids, remember, don't try this at home. 237 00:14:27,560 --> 00:14:31,560 Why do I always laugh when you get hurt? That looks so bad. 238 00:14:31,560 --> 00:14:34,560 I can't believe you did that. 239 00:14:34,560 --> 00:14:36,560 I thought I was going to make it. 240 00:14:36,560 --> 00:14:40,560 We're doing a hole in a V to help guide it. 241 00:14:40,560 --> 00:14:47,560 Just like a pole vault, the hole should guide and catch the driveshaft, lifting the car into the air. 242 00:14:47,560 --> 00:14:52,560 This is three feet wide here. I measured four feet from inside to inside on the tires. 243 00:14:52,560 --> 00:15:00,560 And the goal is to actually release it back here about 20 feet to try and do that and then have it slide into the hole. 244 00:15:00,560 --> 00:15:05,560 Oh, okay. So what if the friction of the asphalt just kicks it up before you even get to the hole? 245 00:15:05,560 --> 00:15:09,560 We're prepared for all those things, but here's hoping that it works the first time out. 246 00:15:09,560 --> 00:15:12,560 Yeah, as it rarely does. 247 00:15:22,560 --> 00:15:26,560 I have to say, the jackhammer makes you look really tough. A little red wagon? 248 00:15:26,560 --> 00:15:28,560 Not so much. 249 00:15:30,560 --> 00:15:33,560 Big ass pothole. I wouldn't want to go into that. 250 00:15:33,560 --> 00:15:36,560 Boy, this is a crapshoot, isn't it? 251 00:15:37,560 --> 00:15:41,560 This is one of our biggest crapshoots yet. Yeah, without a doubt. 252 00:15:42,560 --> 00:15:46,560 Despite the odds, our crapshooters are staying relaxed. 253 00:15:47,560 --> 00:15:50,560 I can sit here and watch them do that all day. 254 00:15:50,560 --> 00:15:57,560 It's delivery day for the star of the exploding Porta Potti experiment. 255 00:15:57,560 --> 00:16:02,560 One used Porta Potti for a methane demolition. Sign here. 256 00:16:02,560 --> 00:16:05,560 This one empties? Yeah, I hope so. 257 00:16:08,560 --> 00:16:11,560 Oh, man. Do I have to go to the toilet? 258 00:16:11,560 --> 00:16:13,560 No, I don't. 259 00:16:13,560 --> 00:16:15,560 I'm not going to. 260 00:16:16,560 --> 00:16:22,560 Oh, man. Do I have the best job or what? 261 00:16:25,560 --> 00:16:29,560 The build team want to see if methane can fuel a Porta Potti explosion. 262 00:16:29,560 --> 00:16:33,560 So first, they need a hole to pump the methane gas in. 263 00:16:34,560 --> 00:16:36,560 What is on your forehead? 264 00:16:37,560 --> 00:16:41,560 Is it poop? Oh, there's some crust on the side of your head. I'm not getting it for you. 265 00:16:42,560 --> 00:16:45,560 Oh, right there. Yeah, wipe that off. 266 00:16:46,560 --> 00:16:49,560 A vent hole will help blow the gas out if it doesn't ignite. 267 00:16:50,560 --> 00:16:52,560 Oh, it is nut-prick! 268 00:16:55,560 --> 00:16:58,560 Tori needs an ignition source for the methane. 269 00:16:58,560 --> 00:17:04,560 And what could be better than Adam's lighter rig from the original exploding toilet myth? 270 00:17:05,560 --> 00:17:07,560 See how well it works now? 271 00:17:08,560 --> 00:17:10,560 With my modifications. 272 00:17:12,560 --> 00:17:14,560 There we go. 273 00:17:15,560 --> 00:17:17,560 Tori thinks he can improve on Adam's rig. 274 00:17:17,560 --> 00:17:21,560 And the master has some advice for his lighting apprentice. 275 00:17:21,560 --> 00:17:27,560 Go to a store that sells a bunch of, like, a smoke shop and get five or six different kinds of lighters. 276 00:17:27,560 --> 00:17:30,560 Choose the one we think is most reliable and most available. 277 00:17:31,560 --> 00:17:36,560 Adam is keen for Tori to build a protective casing for the lighter rig. 278 00:17:36,560 --> 00:17:38,560 But something that can handle an explosion. 279 00:17:38,560 --> 00:17:40,560 That way we don't burn Jamie's servo. 280 00:17:40,560 --> 00:17:41,560 We don't burn the servo we don't. 281 00:17:41,560 --> 00:17:42,560 On the lighter. 282 00:17:44,560 --> 00:17:47,560 Oh, God! Somebody's showering today. 283 00:17:48,560 --> 00:17:49,560 In disinfectant. 284 00:17:50,560 --> 00:17:57,560 So after many hours of rethinking and re-figuring, I came up with the new ignition system. 285 00:17:57,560 --> 00:17:59,560 I call it Block O Wood. 286 00:17:59,560 --> 00:18:02,560 It's a little simpler than Adam's. I hope it works. 287 00:18:08,560 --> 00:18:23,560 Yeah! See? Simple can always be better. 288 00:18:24,560 --> 00:18:26,560 Adam just needs to learn that. 289 00:18:27,560 --> 00:18:29,560 You know when I woke up this morning, I thought, what do I really want to do? 290 00:18:29,560 --> 00:18:31,560 I want to test Adam's poo. 291 00:18:32,560 --> 00:18:36,560 Carrie has her second date with Adam's methane producing flasks. 292 00:18:36,560 --> 00:18:41,560 It has a slightly higher reading than control, but it's still not registering. 293 00:18:41,560 --> 00:18:45,560 There's really not a good enough methane gas buildup in here. 294 00:18:46,560 --> 00:18:54,560 With a second low methane reading, it's looking unlikely that human waste caused the methane blast in the West Virginia Portapotty. 295 00:18:55,560 --> 00:18:59,560 They'll use commercial bottled methane gas for the next test. 296 00:19:00,560 --> 00:19:06,560 And at Portapotty Central, there's a lot to get right. 297 00:19:07,560 --> 00:19:10,560 There's myth busters. Of course I'm expecting problems. 298 00:19:12,560 --> 00:19:17,560 The San Francisco Fire Department will deal with any toilet infernos. 299 00:19:17,560 --> 00:19:18,560 Come on, Lazy! 300 00:19:19,560 --> 00:19:23,560 And Scotty and Christine will deal with any grass that needs watering. 301 00:19:24,560 --> 00:19:34,560 The gas will be pumped into the toilet, and it can also be ventilated out from a safety zone 100 feet away. 302 00:19:34,560 --> 00:19:35,560 Go ahead. 303 00:19:35,560 --> 00:19:37,560 Okay, I'm just turning the tank on now. 304 00:19:37,560 --> 00:19:39,560 I'm already getting a reading. 305 00:19:39,560 --> 00:19:45,560 The methane meter will be critical.
