Go. 256 00:15:19,000 --> 00:15:21,000 Welcome to the Myth Crackers. 257 00:15:21,000 --> 00:15:24,000 Adam and Jamie have hit Springfield again. 258 00:15:24,000 --> 00:15:28,000 Tonight we take on the classic myth that a cat will always land on its feet. 259 00:15:29,000 --> 00:15:34,000 But this time, instead of experimenting as animated characters... 260 00:15:34,000 --> 00:15:36,000 What was it we were trying to prove again? 261 00:15:36,000 --> 00:15:38,000 Don't know, don't care. 262 00:15:40,000 --> 00:15:43,000 They're animatively experimenting. 263 00:15:44,000 --> 00:15:48,000 And with a transparent trio of toilets ready to blow, 264 00:15:49,000 --> 00:15:54,000 they want to know if Bart's bomb could have really gushed multiple geysers. 265 00:15:57,000 --> 00:16:00,000 Now what happens when you flush a cherry bomb down one of these toilets? 266 00:16:00,000 --> 00:16:04,000 Well, it's going to go down through the plumbing and it could blow anywhere. 267 00:16:04,000 --> 00:16:07,000 It could blow here, it could blow here, it could blow down there. 268 00:16:07,000 --> 00:16:09,000 That's actually what these black caps are. 269 00:16:09,000 --> 00:16:14,000 These are places in the plumbing system we can introduce the pressure from the cherry bomb. 270 00:16:14,000 --> 00:16:16,000 But we're not going to use a cherry bomb. 271 00:16:16,000 --> 00:16:17,000 Not in my shop, we're not. 272 00:16:17,000 --> 00:16:19,000 Number one, it's illegal. 273 00:16:19,000 --> 00:16:25,000 And number two, it's potentially dangerous and definitely very messy. 274 00:16:25,000 --> 00:16:28,000 So we're going to need a little bit more control if we're going to do it here. 275 00:16:28,000 --> 00:16:32,000 For that, we have my little pop gun, which has a fast-acting valve on it 276 00:16:32,000 --> 00:16:35,000 that releases a blast of pressurized air. 277 00:16:37,000 --> 00:16:39,000 And that's essentially what an explosion does. 278 00:16:39,000 --> 00:16:43,000 It creates a volume of rapidly expanding gases in a pressure wave. 279 00:16:43,000 --> 00:16:47,000 So we're going to plumb my little pop gun into Adam's rig in various places, 280 00:16:47,000 --> 00:16:50,000 adjust the pressure and see what happens. 281 00:16:50,000 --> 00:16:51,000 20 psi? 282 00:16:51,000 --> 00:16:53,000 Yeah, that's a big fat dump. 283 00:16:54,000 --> 00:16:55,000 Of pressure. 284 00:16:57,000 --> 00:16:58,000 Nice. 285 00:16:58,000 --> 00:16:59,000 Let me know when you're ready. 286 00:16:59,000 --> 00:17:01,000 All right, I'm going to count it down. 287 00:17:01,000 --> 00:17:10,000 Cherry bomb, half-scale toilet experiment, position number one, explosion in three, two, one, go. 288 00:17:13,000 --> 00:17:22,000 A simultaneous tsunami and the physics of Springfield are looking surprisingly accurate. 289 00:17:22,000 --> 00:17:25,000 This first test showed that pressure delivered to the middle toilet 290 00:17:25,000 --> 00:17:29,000 was pretty evenly distributed to the other toilets around it. 291 00:17:29,000 --> 00:17:30,000 It's quite pretty, actually. 292 00:17:30,000 --> 00:17:33,000 Yeah, it's like a little bit of a water ballet. 293 00:17:33,000 --> 00:17:35,000 Some sort of modern art. 294 00:17:36,000 --> 00:17:41,000 Now we want to know what would happen if the cherry bomb and its pressure went here or here. 295 00:17:41,000 --> 00:17:43,000 Would that make any difference? 296 00:17:46,000 --> 00:17:51,000 I don't know about you folks, but whenever I go to the toilet, I always take my umbrella. 297 00:17:51,000 --> 00:18:01,000 Half-scale cherry bomb toilet experiment, position number two, two, explosion in three, two, one, go. 298 00:18:05,000 --> 00:18:07,000 That's very satisfying. 299 00:18:08,000 --> 00:18:11,000 Another successful concurrent eruption. 300 00:18:12,000 --> 00:18:14,000 Position number three, go. 301 00:18:14,000 --> 00:18:18,000 One that's replicated regardless of where the explosion originates. 302 00:18:20,000 --> 00:18:23,000 Which kind of makes sense because there's resistance in each of these toilets, 303 00:18:23,000 --> 00:18:28,000 and so with multiple inlets, that resistance is going to tend to equalize the pressure. 304 00:18:28,000 --> 00:18:29,000 Yeah. 305 00:18:29,000 --> 00:18:33,000 The pressure spread is plausible, but Adam has an issue with volume. 306 00:18:33,000 --> 00:18:38,000 Now, up until now, we've been experimenting with a properly set up plumbing system, 307 00:18:38,000 --> 00:18:41,000 but it's not quite the fountain of water that we see in the show 308 00:18:41,000 --> 00:18:44,000 because there's just not enough water in the system. 309 00:18:44,000 --> 00:18:47,000 But what if there is a clog in the system? 310 00:18:47,000 --> 00:18:48,000 Here we go. 311 00:18:48,000 --> 00:18:53,000 The clog could have water backed up in that system, and the cherry bomb could go in that, 312 00:18:53,000 --> 00:18:55,000 and then it's pushing water. 313 00:18:56,000 --> 00:18:57,000 What do you think? 314 00:18:57,000 --> 00:18:59,000 That's about got it. 315 00:18:59,000 --> 00:19:00,000 All right. 316 00:19:00,000 --> 00:19:02,000 What happens to that water?
