So I'd pull the whole car off and do a proper job. 196 00:11:39,000 --> 00:11:42,000 But this is one moody machine. 197 00:11:45,000 --> 00:11:47,000 No! 198 00:11:47,000 --> 00:11:51,000 And the curse of the cantakorous boom lift strikes. 199 00:11:51,000 --> 00:11:54,000 Watch out, watch out, sorry. Oh, we got an emergency. 200 00:11:54,000 --> 00:11:56,000 Kari cops an eye full of gas. 201 00:11:56,000 --> 00:11:58,000 Yeah. 202 00:11:58,000 --> 00:12:00,000 Go down, go down, go down. 203 00:12:00,000 --> 00:12:02,000 It's like the ocean. 204 00:12:02,000 --> 00:12:04,000 How long do you do this before it's at home? 205 00:12:04,000 --> 00:12:06,000 You can do it for at least 15 minutes. 206 00:12:06,000 --> 00:12:08,000 Kari'll be okay. 207 00:12:08,000 --> 00:12:10,000 Well, it's a little red. 208 00:12:10,000 --> 00:12:11,000 A little red. 209 00:12:11,000 --> 00:12:17,000 As for the Tosser, it only works in fits and starts. 210 00:12:17,000 --> 00:12:19,000 Want to push that button? 211 00:12:20,000 --> 00:12:24,000 Still, that might be enough to test this myth. 212 00:12:25,000 --> 00:12:31,000 Okay, so our next step is to attach a chain between the engine and the basket with a quick release. 213 00:12:31,000 --> 00:12:35,000 And then we'll pull the quick release when we have it under tension and see how far Buster goes. 214 00:12:35,000 --> 00:12:37,000 Now take a ride. 215 00:12:37,000 --> 00:12:41,000 Not surprisingly, Buster seems a little reluctant to get on the boom lift. 216 00:12:41,000 --> 00:12:43,000 Buster! 217 00:12:43,000 --> 00:12:45,000 Come on, stop climbing around. 218 00:12:45,000 --> 00:12:47,000 What is this? Pants. 219 00:12:53,000 --> 00:12:58,000 As per the myth, a car engine will dangle from a length of chain under the lift. 220 00:12:58,000 --> 00:13:03,000 Just to note, it takes quite a lot of force to move the quick release under load. 221 00:13:03,000 --> 00:13:05,000 How did you guys do it? You need to deal with it? 222 00:13:05,000 --> 00:13:08,000 I did it with a piece of 16th inch cable. 223 00:13:08,000 --> 00:13:09,000 Okay. 224 00:13:09,000 --> 00:13:15,000 And not only that, the quick release requires an up pull or a down pull, so you'll need to rig a pulley in line. 225 00:13:15,000 --> 00:13:18,000 So you can transfer that force from the side. 226 00:13:18,000 --> 00:13:21,000 Because you don't want to be anywhere near it when it goes off. 227 00:13:25,000 --> 00:13:28,000 You're not doing it the Jamie way, obviously. 228 00:13:28,000 --> 00:13:30,000 I know, I'm doing it the Adam way. 229 00:13:30,000 --> 00:13:32,000 Quick and dirty, but it gets done. 230 00:13:32,000 --> 00:13:34,000 It looks like these kind of accidents happen all the time. 231 00:13:34,000 --> 00:13:39,000 It's actually more of a question with this myth whether Buster's going to be shot over a house 232 00:13:39,000 --> 00:13:42,000 or if he's just going to tumble out of the basket under the ground. 233 00:13:42,000 --> 00:13:46,000 For the first test, the tosser's arm won't be extended. 234 00:13:46,000 --> 00:13:50,000 Now, just got to work out who's going to operate the quick release. 235 00:13:50,000 --> 00:13:52,000 Road, sham, butt. 236 00:13:53,000 --> 00:13:55,000 Hot man, now. 237 00:13:55,000 --> 00:13:56,000 Alright, whoa, whoa. 238 00:13:56,000 --> 00:13:59,000 It's face off. Me and Scotty. 239 00:14:03,000 --> 00:14:06,000 Looks like Scotty wins. 240 00:14:06,000 --> 00:14:08,000 Right, it's the moment of truth. 241 00:14:08,000 --> 00:14:13,000 Will Buster be a far flung dummy or is this myth far fetched? 242 00:14:13,000 --> 00:14:18,000 Five, four, three, two, one. 243 00:14:20,000 --> 00:14:21,000 Wow. 244 00:14:21,000 --> 00:14:22,000 That was cool. 245 00:14:22,000 --> 00:14:23,000 Buster. 246 00:14:24,000 --> 00:14:25,000 He didn't even move. 247 00:14:25,000 --> 00:14:27,000 Buster barely wobbled. 248 00:14:27,000 --> 00:14:30,000 Well, that was the most anemic catapult I've ever seen. 249 00:14:30,000 --> 00:14:32,000 In fact, Buster didn't even budge. 250 00:14:32,000 --> 00:14:35,000 He didn't like quiver hardly on that one. 251 00:14:35,000 --> 00:14:41,000 So now we're going to lift the boom up to where it's kind of in the same position 252 00:14:41,000 --> 00:14:43,000 and extend it all the way out from there. 253 00:14:43,000 --> 00:14:49,000 And I'm hoping that that'll actually create a little bit more of a whip when we let go of the engine. 254 00:14:49,000 --> 00:14:51,000 Alright, I'm going to count down. 255 00:14:51,000 --> 00:14:54,000 49, 48. 256 00:14:54,000 --> 00:14:55,000 Scotty. 257 00:14:55,000 --> 00:14:59,000 Five, four, three, two, one. 258 00:15:01,000 --> 00:15:03,000 And Buster didn't even spill his coffee. 259 00:15:03,000 --> 00:15:05,000 He didn't even drop the cup. 260 00:15:06,000 --> 00:15:09,000 Well, Scotty's had an idea. 261 00:15:09,000 --> 00:15:13,000 Well, I'm thinking that if this guy was pulling it from a car and he was up in the basket, 262 00:15:13,000 --> 00:15:16,000 the engine might have been caught on something. 263 00:15:16,000 --> 00:15:19,000 And he couldn't tell and that would have been enough to break the chain. 264 00:15:20,000 --> 00:15:22,000 So should we get the caddy in here? 265 00:15:22,000 --> 00:15:23,000 It's Earl's turn. 266 00:15:23,000 --> 00:15:25,000 Alright, let's hook it up to the caddy. 267 00:15:25,000 --> 00:15:28,000 Jamie, like Buster, is unmoved. 268 00:15:28,000 --> 00:15:35,000 Even if it was double what it just did, which it won't do, you know, nothing's going to happen. 269 00:15:35,000 --> 00:15:38,000 If Scotty believes it can happen, that means a lot of people believe it can happen, 270 00:15:38,000 --> 00:15:39,000 so we should try to prove it. 271 00:15:39,000 --> 00:15:40,000 It'll be thorough. 272 00:15:40,000 --> 00:15:42,000 Okay, let me know when you're ready. 273 00:15:44,000 --> 00:15:48,000 The size of the boom lift might actually be working against them. 274 00:15:48,000 --> 00:15:52,000 The tosser's big enough to absorb the force of the engine's sudden release. 275 00:15:52,000 --> 00:15:55,000 Will Earl's weight make any difference? 276 00:15:56,000 --> 00:16:00,000 Five, four, three, two, one. 277 00:16:04,000 --> 00:16:05,000 Wow. 278 00:16:05,000 --> 00:16:07,000 Dude, he's still holding onto his coffee. 279 00:16:07,000 --> 00:16:08,000 Well, there you go. 280 00:16:08,000 --> 00:16:10,000 We're going to have to elaborate on the myth. 281 00:16:10,000 --> 00:16:12,000 We're going to have to do this myth busters way? 282 00:16:12,000 --> 00:16:13,000 Yeah. 283 00:16:13,000 --> 00:16:19,000 Doing things the myth busters way usually spells trouble on a tight, tannic scale. 284 00:16:19,000 --> 00:16:23,000 The build team has an idea and it's a biggie. 285 00:16:23,000 --> 00:16:27,000 But before they go big, they've got to go small. 286 00:16:27,000 --> 00:16:31,000 Tori sets about building a scale model boom lift. 287 00:16:31,000 --> 00:16:34,000 What we're trying to do is turn this boom lift into a catapult. 288 00:16:34,000 --> 00:16:39,000 So an idea we came up with was turning the front axles into an actual pivot point. 289 00:16:39,000 --> 00:16:40,000 Raising... 290 00:16:40,000 --> 00:16:44,000 And then just using the weight of the body of the thing as the catapult weight to. 291 00:16:44,000 --> 00:16:45,000 Exactly. 292 00:16:45,000 --> 00:16:48,000 What we're going to do is we're going to raise it up, grab these points here, 293 00:16:48,000 --> 00:16:52,000 and then let the actual thing swing forward, just like that. 294 00:16:52,000 --> 00:16:54,000 So this is a scale model. 295 00:16:54,000 --> 00:16:59,000 And then we have scale model truck containers that we're going to use to put this on and use it to lift it up. 296 00:16:59,000 --> 00:17:01,000 You think those will be strong enough? 297 00:17:01,000 --> 00:17:02,000 The truck containers? 298 00:17:02,000 --> 00:17:03,000 Yeah. 299 00:17:03,000 --> 00:17:04,000 I don't know. 300 00:17:04,000 --> 00:17:05,000 I mean, how much does this thing weigh? 301 00:17:05,000 --> 00:17:08,000 This thing actually weighs around 25,000 pounds. 302 00:17:08,000 --> 00:17:11,000 I can reinforce those. 303 00:17:11,000 --> 00:17:14,000 Well, it also looks like it's not quite high enough to get a full swing. 304 00:17:14,000 --> 00:17:17,000 If you wanted to catapult something, you needed it to go all the way over, right? 305 00:17:17,000 --> 00:17:18,000 Yeah. 306 00:17:18,000 --> 00:17:20,000 Right now we're hitting right there. 307 00:17:20,000 --> 00:17:21,000 So we've got to go up higher? 308 00:17:21,000 --> 00:17:23,000 We'll probably have to get two containers. 309 00:17:23,000 --> 00:17:24,000 They're totally stacked. 310 00:17:24,000 --> 00:17:26,000 You can stack them and lock them together, right? 311 00:17:26,000 --> 00:17:27,000 Yeah. 312 00:17:27,000 --> 00:17:29,000 Well, no guts, no glory. 313 00:17:29,000 --> 00:17:34,000 How about a little demonstration using a cutout Jamie doll? 314 00:17:34,000 --> 00:17:37,000 Well, that's not too bad. 315 00:17:37,000 --> 00:17:40,000 That might have made it, you know, like 80, 100 feet or something. 316 00:17:40,000 --> 00:17:42,000 I think that's pretty good. 317 00:17:42,000 --> 00:17:47,000 What Tori's proposing to build is called a counterweight trebuchet. 318 00:17:47,000 --> 00:17:52,000 This type of catapult, which was popular in the Middle Ages, lets gravity do the work. 319 00:17:52,000 --> 00:17:56,000 Big rock at one end, even bigger counterweight at the other. 320 00:17:56,000 --> 00:18:01,000 When fired, the counterweight drops and the big rock goes about its business, 321 00:18:01,000 --> 00:18:04,000 certain to cause belligerence on the battlements. 322 00:18:04,000 --> 00:18:08,000 You black-hearted, bespilling dog. 323 00:18:08,000 --> 00:18:11,000 Never you, well-named poacher. 324 00:18:11,000 --> 00:18:15,000 And this would have to be the mother of all trebuchets. 325 00:18:15,000 --> 00:18:19,000 A colossal catapult in the heart of rural England. 326 00:18:19,000 --> 00:18:23,000 Built by a medieval enthusiast with a lot of time on his hands, 327 00:18:23,000 --> 00:18:28,000 this 30-ton monster has no problem flinging fiery fuel bombs. 328 00:18:28,000 --> 00:18:45,000 Oh, and if you're in the area, don't leave your vehicle unattended. 329 00:18:45,000 --> 00:18:57,000 Well, not bad, eh? 330 00:18:57,000 --> 00:18:58,000 Not bad. 331 00:18:58,000 --> 00:19:00,000 Smashed it up pretty nice. 332 00:19:00,000 --> 00:19:02,000 It won't drive again anyway, I don't think. 333 00:19:02,000 --> 00:19:04,000 Not very well, no. 334 00:19:04,000 --> 00:19:09,000 Will the tosser be able to wreak similar havoc? 335 00:19:09,000 --> 00:19:12,000 Turning heavy machinery into a medieval weapon. 336 00:19:13,000 --> 00:19:17,000 It doesn't get any more mythbusters than that. 337 00:19:17,000 --> 00:19:23,000 Still to come, it's all hands on deck as the boom lift becomes the world's biggest catapult. 338 00:19:23,000 --> 00:19:32,000 And next, which sucks up more fuel, raging air conditioning, or rolling down your windows? 339 00:19:42,000 --> 00:19:48,000 With world oil prices on the rise, everyone's looking for ways to save pennies at the pump. 340 00:19:48,000 --> 00:19:51,000 How can you get better fuel economy? 341 00:19:51,000 --> 00:19:54,000 Gentlemen, start your engines. 342 00:19:59,000 --> 00:20:01,000 So is this really an urban legend, Jamie? 343 00:20:01,000 --> 00:20:04,000 No, it's more of an urban puzzle. 344 00:20:04,000 --> 00:20:09,000 Like one of those things you would discuss endlessly, sitting in traffic, or debate on a road trip. 345 00:20:09,000 --> 00:20:20,000 Yeah, the idea is that on a really hot day, it's more efficient to run with your air conditioning on full blast and your windows up than it is to drive with the windows down and the AC off. 346 00:20:20,000 --> 00:20:22,000 Well, that seems pretty logical, that seems right to me. 347 00:20:22,000 --> 00:20:25,000 I don't know about that. AC use is an awful lot of power. 348 00:20:25,000 --> 00:20:29,000 Oh, I think a car with a windows open is creating an awful lot of drag. 349 00:20:29,000 --> 00:20:31,000 That's what makes it a perfect test for mythbusters. 350 00:20:31,000 --> 00:20:33,000 And that would be us. 351 00:20:33,000 --> 00:20:34,000 That would be us. 352 00:20:34,000 --> 00:20:35,000 Alright. 353 00:20:35,000 --> 00:20:42,000 Ever since the first auto air conditioners arrived in the 1940s, drivers have asked the question, 354 00:20:42,000 --> 00:20:48,000 do you get better fuel economy with the AC on or the windows down? 355 00:20:48,000 --> 00:20:54,000 The mythbusters are about to run two tests to find out once and for all. 356 00:20:54,000 --> 00:20:59,000 Auto computer gurus Bob and Jesse are helping out with the first test. 357 00:20:59,000 --> 00:21:05,000 This computer will measure fuel consumption by monitoring the rate of air flow through the SUV's engine. 358 00:21:05,000 --> 00:21:10,000 This is going to calculate our average miles per gallon. This is our estimated miles per gallon. 359 00:21:10,000 --> 00:21:18,000 We've got a computer hooked up to the car. We're going to do 15 laps, 5 with the windows up, 5 with the windows down, and 5 with the windows up and the AC on full. 360 00:21:18,000 --> 00:21:23,000 We're going to see if the computer shows us a significant difference in the mileage of the car in those conditions. 361 00:21:23,000 --> 00:21:25,000 Time to hit the road. 362 00:21:25,000 --> 00:21:32,000 Alright, on my countdown in 5, 4, 3, 2, 1, go. 363 00:21:32,000 --> 00:21:39,000 The first 5 laps will measure fuel consumption with the windows up and the AC off. 364 00:21:39,000 --> 00:21:43,000 Now, this won't be a leisurely Sunday drive. 365 00:21:43,000 --> 00:21:50,000 SUV's aren't built for racetracks. Their tires certainly aren't. Also, the track is banked. 366 00:21:50,000 --> 00:21:53,000 And Jamie will have to concentrate all the way. 367 00:21:53,000 --> 00:22:02,000 Jamie's going to hate this a lot more than I am. I mean, I'm not going to find it pleasant, but I get so much pleasure out of his discomfort. 368 00:22:02,000 --> 00:22:07,000 You know, Jamie, they regularly pull 160 miles per hour on the track. 369 00:22:07,000 --> 00:22:11,000 I'm not going to be laughing in a couple of minutes when I'm plowing one of these behemoths across the lanes. 370 00:22:11,000 --> 00:22:15,000 Jamie keeps the needle hovering at around 55 miles per hour. 371 00:22:15,000 --> 00:22:20,000 After 5 laps with the windows up, the fuel consumption figures are in. 372 00:22:20,000 --> 00:22:24,000 Right now we're averaging 11.7 miles to a gallon. 373 00:22:24,000 --> 00:22:27,000 Now it's time to roll the windows down. 374 00:22:27,000 --> 00:22:35,000 It looks like we're averaging about 11.4 to 11.3 with all the windows down in the vehicle. 375 00:22:35,000 --> 00:22:41,000 Jamie, you're doing great. You are a tribute to American individualism. 376 00:22:41,000 --> 00:22:43,000 I wish I could see his face right now. 377 00:22:43,000 --> 00:22:48,000 It would be completely impassive. You wouldn't see a single change on it. 378 00:22:49,000 --> 00:22:57,000 That's windows up and AC on. Repeat, windows up and AC on. This is the last 5 laps. 379 00:23:03,000 --> 00:23:05,000 We're averaging 11.7. 380 00:23:08,000 --> 00:23:10,000 So we're averaging 11.7. 381 00:23:12,000 --> 00:23:17,000 Jamie gets the checkered flag, but that SUV is no race car. 382 00:23:19,000 --> 00:23:24,000 I gotta say it's pretty intense and I'm going to be ill. 383 00:23:24,000 --> 00:23:29,000 We are going to be dead after this is over as far from exhaustion. 384 00:23:29,000 --> 00:23:35,000 I was starting to get a little more relaxed in it trying to lay back and go, 385 00:23:35,000 --> 00:23:38,000 you know, no big deal. 386 00:23:38,000 --> 00:23:44,000 You have to focus. It was a real stretch for me even to open and close the windows doing that. 387 00:23:44,000 --> 00:23:47,000 What was the difference in actual miles per gallon? 388 00:23:47,000 --> 00:23:52,000 With the windows up and AC on, it was right around 11.7 and 11.8. 389 00:23:52,000 --> 00:23:55,000 With AC on and off, it didn't make a difference that much. 390 00:23:55,000 --> 00:24:01,000 With the windows down, it was 11.3 and that's where it was making a difference with the drag of the wind. 391 00:24:01,000 --> 00:24:04,000 Wow. That seems pretty significant over a full tank of gas. 392 00:24:04,000 --> 00:24:05,000 Oh yeah. Big time. 393 00:24:05,000 --> 00:24:10,000 So clearly it's more efficient to drive with the windows up and the air conditioning on 394 00:24:10,000 --> 00:24:12,000 than to drive with the windows down. 395 00:24:12,000 --> 00:24:14,000 Yeah, definitely. 396 00:24:14,000 --> 00:24:15,000 That's what the computer said. 397 00:24:15,000 --> 00:24:17,000 So that's that all figured out. 398 00:24:17,000 --> 00:24:20,000 Not quite. There's still a question mark. 399 00:24:20,000 --> 00:24:23,000 See, those figures are based on a computer model. 400 00:24:23,000 --> 00:24:26,000 That model assumes ideal conditions. 401 00:24:26,000 --> 00:24:31,000 Adam and Jamie like to test things out for themselves. 402 00:24:31,000 --> 00:24:34,000 That's why they're doing the Average Joe test. 403 00:24:34,000 --> 00:24:37,000 Okay everybody from Jamie's car, come on, get on the scale. 404 00:24:37,000 --> 00:24:43,000 Two identical SUVs, two full tanks and two identical payloads. 405 00:24:43,000 --> 00:24:46,000 Everybody in Adam's car, let's get weighed in. Come on. 406 00:24:46,000 --> 00:24:50,000 One SUV has the AC on and the other has the window down. 407 00:24:50,000 --> 00:24:56,000 The logic is simple. The vehicle that uses the most gas will stop first. 408 00:24:56,000 --> 00:25:01,000 It'll be a seven hour marathon and the boys have to be prepared. 409 00:25:01,000 --> 00:25:06,000 I got a whole regimen. I got bananas, I got cookies, I got candies, I got lots of coffee 410 00:25:06,000 --> 00:25:08,000 and I got lots of music. 411 00:25:08,000 --> 00:25:10,000 Come on Jamie. 412 00:25:10,000 --> 00:25:13,000 Don't knock it till you've tried it. 413 00:25:13,000 --> 00:25:17,000 Think twice before accepting a dinner invitation to Jamie's house. 414 00:25:17,000 --> 00:25:19,000 This is lunch. 415 00:25:19,000 --> 00:25:22,000 Question is, has he already eaten it? 416 00:25:22,000 --> 00:25:28,000 This particular batch, I call the 440 Fort, has four fruits, four vegetables and four grains. 417 00:25:28,000 --> 00:25:32,000 It actually tastes quite nice. It's sort of like a spacho. 418 00:25:32,000 --> 00:25:35,000 Sure it does Jamie, but how do you actually eat it? 419 00:25:35,000 --> 00:25:39,000 Split the corner of it. This is sort of dripping because I had to thaw it. 420 00:25:39,000 --> 00:25:43,000 And you just kind of go like that and it down it goes. 421 00:25:43,000 --> 00:25:48,000 Don't know how he's going to manage that while driving around a racetrack at 55 miles per hour. 422 00:25:51,000 --> 00:25:53,000 Let's suffer together brother. 423 00:25:53,000 --> 00:26:01,000 Well, you know, and also remember going at that speed on this track, if you have a blowout, it may not be a safe thing. 424 00:26:01,000 --> 00:26:02,000 Later. 425 00:26:02,000 --> 00:26:04,000 And away we go. 426 00:26:04,000 --> 00:26:10,000 Jamie's got the AC on. Adam has the windows down. Who will run out of gas first? 427 00:26:10,000 --> 00:26:14,000 I would not have called that at all. I'm really surprised. I'm shocked even. 428 00:26:14,000 --> 00:26:20,000 And up next, the danger levels reach critical as the boom lift catapult prepares to fire. 429 00:26:20,000 --> 00:26:23,000 Once this thing is up in the air, we're not going to hear it. 430 00:26:35,000 --> 00:26:37,000 To work. 431 00:26:37,000 --> 00:26:39,000 The boom lift myths already been busted. 432 00:26:39,000 --> 00:26:41,000 And Buster didn't even spill his coffee. 433 00:26:41,000 --> 00:26:48,000 There's no way a person could be hurled 200 feet from a 60 foot boom lift under normal circumstances. 434 00:26:48,000 --> 00:26:51,000 But how about abnormal circumstances? 435 00:26:59,000 --> 00:27:01,000 I'm getting my pork lift lesson for the day. 436 00:27:05,000 --> 00:27:07,000 I'm going to get some gas. 437 00:27:11,000 --> 00:27:20,000 Here's the plan. The 30,000 pound boom lift will be placed on top of four storage containers with its front axle acting as a pivot point. 438 00:27:20,000 --> 00:27:30,000 The arm will be cocked and when it's released, the massive weight of the swinging machine will catapult poor old Buster through space like Mitty Vellamo. 439 00:27:30,000 --> 00:27:34,000 It's audacious. It's ludicrous. It's myth busters. 440 00:27:39,000 --> 00:27:42,000 First, the containers have to be stacked. 441 00:27:46,000 --> 00:27:48,000 Let's go up. 442 00:27:51,000 --> 00:27:54,000 You need to pull it so we get parallel. 443 00:27:54,000 --> 00:27:56,000 Yeah. 444 00:27:56,000 --> 00:27:57,000 Okay. 445 00:28:01,000 --> 00:28:02,000 Good. 446 00:28:02,000 --> 00:28:04,000 I hope the rest of it is that easy. 447 00:28:04,000 --> 00:28:07,000 You just totally jinxed us. 448 00:28:07,000 --> 00:28:09,000 This is going to be awesome. 449 00:28:09,000 --> 00:28:14,000 Can you imagine that 30,000 pound man lift just swinging through here? 450 00:28:14,000 --> 00:28:16,000 It's going to be ridiculous. 451 00:28:16,000 --> 00:28:20,000 This is what I like. There's so much potential for a huge disaster. 452 00:28:20,000 --> 00:28:23,000 I would plant it from the top. 453 00:28:23,000 --> 00:28:27,000 The containers will have to be reinforced to take the weight of the boom lift. 454 00:28:27,000 --> 00:28:29,000 All right. 455 00:28:29,000 --> 00:28:35,000 The engineering that we're doing here is just kind of gut by gut and by seated at the pants. 456 00:28:35,000 --> 00:28:44,000 You know, we know how much this lift over here, the tosser weighs and we know how much the weight of the boom lift is. 457 00:28:44,000 --> 00:28:52,000 We know how much this lift over here, the tosser weighs and we know how much those things weigh. 458 00:28:52,000 --> 00:28:57,000 We're eyeballing the thickness of the steel and the way that they're built and everything. 459 00:28:57,000 --> 00:29:01,000 And my money says that it'll hold just fine. 460 00:29:01,000 --> 00:29:06,000 This whole thing is just really one of the more extravagant stunts that we've done, I think. 461 00:29:09,000 --> 00:29:12,000 Hey, Carrie, make sure we've extended all the way out. 462 00:29:12,000 --> 00:29:14,000 No problem. 463 00:29:14,000 --> 00:29:18,000 Yeah, now let's see whether we can do the same thing here. 464 00:29:18,000 --> 00:29:21,000 The boom arm will be caulked by anchoring it to a weight. 465 00:29:21,000 --> 00:29:24,000 I gotta say, you know, I don't think anybody's ever done this before. 466 00:29:24,000 --> 00:29:29,000 You know, this has to be a world first, either that or it's just stupid. 467 00:29:30,000 --> 00:29:34,000 Next, steel tubes have to be welded onto the front wheels. 468 00:29:34,000 --> 00:29:39,000 These have to support the whole boom lift as it swings down. 469 00:29:39,000 --> 00:29:41,000 So it'd be nice if they didn't come off. 470 00:29:41,000 --> 00:29:44,000 Measuring that hub, it's exactly 11 inches. 471 00:29:44,000 --> 00:29:49,000 And measuring this is exactly 12 inches and you've got exactly half inch stuff there. 472 00:29:49,000 --> 00:29:51,000 There's like no margin of error. 473 00:29:51,000 --> 00:29:54,000 That's why we have a round surface, round stock for shimming the... 474 00:29:54,000 --> 00:29:58,000 Good thing Scotty's on the case. She's a welding wonder. 475 00:30:04,000 --> 00:30:07,000 He's getting through it. He's a good student. 476 00:30:07,000 --> 00:30:09,000 Thank you, Scotty. 477 00:30:09,000 --> 00:30:14,000 It's easy to do things, not easy to think about what to do. 478 00:30:16,000 --> 00:30:18,000 Oh yeah, oh yeah. 479 00:30:18,000 --> 00:30:19,000 Very nice. 480 00:30:19,000 --> 00:30:22,000 We're nearing launch. Where's our catapult seat? 481 00:30:22,000 --> 00:30:27,000 Alright, Buster. No more yoga.

Jamie's AC-cooled SUV is slowing down. 568 00:36:20,000 --> 00:36:22,000 Yeah, I'm coasting now. 569 00:36:22,000 --> 00:36:27,000 Jamie's car just cracked out and mine's still going strong at 45 miles per hour. 570 00:36:27,000 --> 00:36:32,000 Looks like it's more fuel efficient to drive with your windows down than with your AC on. 571 00:36:34,000 --> 00:36:35,000 I don't get it. 572 00:36:35,000 --> 00:36:40,000 So Adam, what do you think? Are you going to keep running for another half hour or what? 573 00:36:40,000 --> 00:36:47,000 I don't know. When I come in I think we're just going to have to bust this myth and say that the fuel efficiency is better with your windows down than with your AC on. 574 00:36:47,000 --> 00:36:50,000 Yeah, that's sort of what the test says, isn't it? Over. 575 00:36:50,000 --> 00:36:54,000 I would not have called that at all. I'm really surprised. I'm shocked even. 576 00:36:57,000 --> 00:37:03,000 30 laps later, Adam's naturally ventilated vehicle finally runs out of gas. 577 00:37:04,000 --> 00:37:09,000 Oh man. I feel like I'm leaning like this. 578 00:37:09,000 --> 00:37:11,000 That totally confounded my expectations. 579 00:37:11,000 --> 00:37:16,000 There's no other way of interpreting it. We've gone over all of the facts of what went on here. 580 00:37:16,000 --> 00:37:18,000 I ran out first by running the AC. 581 00:37:18,000 --> 00:37:23,000 Yeah, 15 miles ago. That's 30 laps that I did that you didn't do. I mean, I'm just like... 582 00:37:28,000 --> 00:37:30,000 Windows versus AC. What's the verdict? 583 00:37:30,000 --> 00:37:36,000 Well, the computer showed that it was actually better to run with the AC on. Not by much, but it was better. 584 00:37:36,000 --> 00:37:41,000 I've got a little bit of a problem with that, which is the computer's actually measuring the air flow into the engine, 585 00:37:41,000 --> 00:37:44,000 not the fuel consumption of the engine. 586 00:37:44,000 --> 00:37:49,000 And it's basing its assessment on a computerized model under ideal circumstances. 587 00:37:49,000 --> 00:37:54,000 Yeah, our average Joe test was pretty straightforward and kind of foolproof. 588 00:37:54,000 --> 00:37:56,000 We put so much gas in, we ran for so long. 589 00:37:56,000 --> 00:38:02,000 And it pretty definitively showed by almost 15% that running with the windows down was a lot more fuel efficient. 590 00:38:02,000 --> 00:38:04,000 Yeah, that's a pretty significant difference. 591 00:38:04,000 --> 00:38:08,000 So, AC being more fuel efficient, I'd say busted. 592 00:38:08,000 --> 00:38:09,000 Busted. 593 00:38:09,000 --> 00:38:10,000 Yeah. 594 00:38:12,000 --> 00:38:15,000 After the break, is this the world's biggest human catapult? 595 00:38:15,000 --> 00:38:18,000 Find out, because we're going to fire it any second now. 596 00:38:28,000 --> 00:38:31,000 The boom lift catapults approaching critical mass. 597 00:38:31,000 --> 00:38:35,000 Five, four, three, two, one. 598 00:38:35,000 --> 00:38:37,000 This myth has already been busted. 599 00:38:37,000 --> 00:38:42,000 There's no way anyone could be thrown 200 feet from a 60 foot boom lift. 600 00:38:42,000 --> 00:38:50,000 Unless, of course, the boom lift happens to be balanced on some shipping containers and rigged to go off like a medieval catapult. 601 00:39:01,000 --> 00:39:11,000 Busters hanging on for dear life. 602 00:39:11,000 --> 00:39:14,000 It's looking good, man.
