88 00:05:02,000 --> 00:05:06,000 She could generate a differential in pressure. 89 00:05:06,000 --> 00:05:11,000 Yeah, the greater pressure inside would actually be trying to push her through the hole. 90 00:05:11,000 --> 00:05:15,000 That theory of toilet terror has one problem. 91 00:05:15,000 --> 00:05:18,000 It could only happen at altitude. 92 00:05:18,000 --> 00:05:27,000 According to the legend and the information that we have, they said that the women actually stayed on the toilet until they were on the ground. 93 00:05:27,000 --> 00:05:30,000 Well, that would rule out the pressure differential area, wouldn't it? 94 00:05:30,000 --> 00:05:31,000 Exactly. 95 00:05:31,000 --> 00:05:34,000 That leaves this vacuum unit. 96 00:05:34,000 --> 00:05:37,000 It has pressure at altitude and on the ground. 97 00:05:37,000 --> 00:05:40,000 The vacuum toilet operates at two different pressures. 98 00:05:40,000 --> 00:05:44,000 On the ground it operates at approximately three psi negative pressure. 99 00:05:44,000 --> 00:05:49,000 And at altitude we operate at eight psi negative pressure. 100 00:05:49,000 --> 00:05:56,000 And that pressure is produced by the differential between inside cabin air and the outside of the aircraft. 101 00:05:56,000 --> 00:05:57,000 This is the one. 102 00:05:57,000 --> 00:06:04,000 But at nine grand, it doesn't come cheap. 103 00:06:04,000 --> 00:06:11,000 One of the biggest problems that I see is that we've got to mimic a woman's butt really well. 104 00:06:11,000 --> 00:06:13,000 It has to be nice and fleshy and soft. 105 00:06:13,000 --> 00:06:17,000 So we've got to decide on what kind of, it's going to be a rubber of some sort. 106 00:06:17,000 --> 00:06:21,000 Well, I've thought of using this rubber that's used in a lot of sex toys because it's very fleshy. 107 00:06:21,000 --> 00:06:23,000 It's called Hot Melt Vinyl. 108 00:06:27,000 --> 00:06:34,000 I'd like to see a sample of the Hot Melt Vinyl you have. 109 00:06:34,000 --> 00:06:35,000 Is this a Hot Melt?

That's no problem at all. 359 00:19:00,000 --> 00:19:03,000 We would want to get the temperature stable 360 00:19:03,000 --> 00:19:06,000 in the car and then move the biscuits right in 361 00:19:06,000 --> 00:19:09,000 and start the timer and see how long it takes them to go off. 362 00:19:11,000 --> 00:19:15,000 Step one in our recipe, getting the dough. 363 00:19:16,000 --> 00:19:19,000 I'm guessing that the different mixes, 364 00:19:19,000 --> 00:19:22,000 like you got your flaky biscuits and you got your, you know, 365 00:19:22,000 --> 00:19:26,000 super-duper buttermilk, whatever, you know, 366 00:19:26,000 --> 00:19:29,000 there's going to be some differences in those things. 367 00:19:29,000 --> 00:19:32,000 That maybe that there's, you know, a certain amount of baking soda 368 00:19:32,000 --> 00:19:37,000 in one as opposed to another that would make it more prone to, you know, 369 00:19:37,000 --> 00:19:39,000 building that high pressure. 370 00:19:39,000 --> 00:19:42,000 The tins are meant to be refrigerated, 371 00:19:42,000 --> 00:19:45,000 so we'll keep them in a cooler until the experiment begins. 372 00:19:46,000 --> 00:19:49,000 I had an idea that, you know, it's not only the car's temperature, 373 00:19:49,000 --> 00:19:52,000 but potentially the freshness of the biscuits 374 00:19:52,000 --> 00:19:55,000 that might have contributed to their exploding. 375 00:19:55,000 --> 00:20:00,000 To that end, we've had this one out for 10 days. 376 00:20:00,000 --> 00:20:03,000 And we'll put that in our, you know, as one of our control groups 377 00:20:03,000 --> 00:20:05,000 to see if it explodes faster. 378 00:20:06,000 --> 00:20:09,000 Step two, mounting the tins in the car. 379 00:20:11,000 --> 00:20:15,000 I was thinking just in terms of being able to get a reasonable spread, 380 00:20:15,000 --> 00:20:17,000 maybe a rack of six. 381 00:20:20,000 --> 00:20:23,000 Maybe for fun we should like make a thing like, you know, 382 00:20:23,000 --> 00:20:27,000 a holster, like shotgun shells, like you're, you know, you're either... 383 00:20:27,000 --> 00:20:29,000 Nobody moves, nobody gets hurt. 384 00:20:32,000 --> 00:20:35,000 Right, wearing it under your mask, going through our play security. 385 00:20:40,000 --> 00:20:44,000 Step three, determining the right baking temperature. 386 00:20:44,000 --> 00:20:47,000 So it's a rare sunny day in San Francisco. 387 00:20:47,000 --> 00:20:51,000 The skies look really clear and it's nine on the nose. 388 00:20:51,000 --> 00:20:53,000 We're going to place a thermometer in my car. 389 00:20:53,000 --> 00:20:55,000 We're going to check back in a couple of hours 390 00:20:55,000 --> 00:20:57,000 and see where we can get the temperature to. 391 00:21:00,000 --> 00:21:03,000 It's no coincidence that the Biscuit Bullet story 392 00:21:03,000 --> 00:21:07,000 first started making the rounds in the summer of 95, 393 00:21:07,000 --> 00:21:09,000 one of the hottest summers on record. 394 00:21:12,000 --> 00:21:14,000 So it's about three o'clock. 395 00:21:14,000 --> 00:21:17,000 The car's been sitting out here all day with the thermometer in it. 396 00:21:17,000 --> 00:21:20,000 Temperature's hovering right around 140 degrees. 397 00:21:22,000 --> 00:21:25,000 To ensure a consistent baking temperature, 398 00:21:25,000 --> 00:21:28,000 we're going to bring the car inside and heat it artificially. 399 00:21:36,000 --> 00:21:37,000 So Adam, let's load this thing. 400 00:21:37,000 --> 00:21:38,000 Okay. 401 00:21:40,000 --> 00:21:44,000 I'm hoping we see a pretty significant change in the heat kind of fast. 402 00:21:44,000 --> 00:21:49,000 Well, it ought to, these are radiant heaters, so, you know, 403 00:21:49,000 --> 00:21:53,000 this is like the pure form of what the sun gives 404 00:21:53,000 --> 00:21:56,000 as far as just what actually heats it up. 405 00:21:56,000 --> 00:21:58,000 We're up to 105.8. 406 00:21:58,000 --> 00:22:00,000 It's looking good. 407 00:22:00,000 --> 00:22:03,000 Maybe another 15 or 20 minutes. 408 00:22:03,000 --> 00:22:05,000 It's going to be hot in there. 409 00:22:05,000 --> 00:22:07,000 I don't know if you want to sit in the car, 410 00:22:07,000 --> 00:22:09,000 you know, wait for the Biscuit Towel, 411 00:22:09,000 --> 00:22:12,000 you know, or if I sit in the car, you know, maybe we take turns. 412 00:22:12,000 --> 00:22:13,000 All right. 413 00:22:13,000 --> 00:22:15,000 I think from about a foot away, you know, 414 00:22:15,000 --> 00:22:17,000 it's totally safe for us to, you know, 415 00:22:17,000 --> 00:22:19,000 be able to be the subjects in the car. 416 00:22:19,000 --> 00:22:22,000 I wouldn't load my shorts full of these things in a hot car. 417 00:22:23,000 --> 00:22:25,000 That's a scary thought. 418 00:22:27,000 --> 00:22:31,000 It's starting to smell really strong of like almost burning plastic in there. 419 00:22:31,000 --> 00:22:33,000 So I don't think either of us should sit in there. 420 00:22:33,000 --> 00:22:35,000 I think they made up a rack. 421 00:22:35,000 --> 00:22:36,000 All right. 422 00:22:36,000 --> 00:22:39,000 I mean, you don't want to get hot as with yourself. 423 00:22:39,000 --> 00:22:43,000 Oh, you couldn't go climbing there, but it's pretty stinky. 424 00:22:43,000 --> 00:22:44,000 You could suffocate. 425 00:22:44,000 --> 00:22:46,000 120 degrees. 426 00:22:46,000 --> 00:22:48,000 Time to get baking. 427 00:22:48,000 --> 00:22:49,000 Are you ready? 428 00:22:49,000 --> 00:22:50,000 Yeah. 429 00:22:50,000 --> 00:22:51,000 Okay. 430 00:22:51,000 --> 00:22:53,000 Leading brand flaky. 431 00:22:53,000 --> 00:22:55,000 Leading brand buttermilk. 432 00:22:55,000 --> 00:22:57,000 Competitor flaky. 433 00:22:57,000 --> 00:23:00,000 Competitor buttermilk. 434 00:23:00,000 --> 00:23:02,000 Unrefrigerated. 435 00:23:02,000 --> 00:23:04,000 Small tin. 436 00:23:06,000 --> 00:23:09,000 And the clock is ticking. 437 00:23:09,000 --> 00:23:13,000 I'll say within eight minutes. 438 00:23:13,000 --> 00:23:16,000 Two hours, maybe three. 439 00:23:16,000 --> 00:23:17,000 Really? 440 00:23:17,000 --> 00:23:18,000 Yeah. 441 00:23:18,000 --> 00:23:23,000 So, do I lose if I go over or if it's closer to eight minutes than two hours? 442 00:23:23,000 --> 00:23:26,000 So we're saying eight minutes or 120 minutes? 443 00:23:26,000 --> 00:23:27,000 Yeah. 444 00:23:27,000 --> 00:23:28,000 All right. 445 00:23:28,000 --> 00:23:30,000 I'll put a dollar down on that. 446 00:23:30,000 --> 00:23:32,000 Put it on the counter. 447 00:23:32,000 --> 00:23:34,000 Put it on the counter. 448 00:23:34,000 --> 00:23:36,000 I'll put a dollar down on that. 449 00:23:36,000 --> 00:23:39,000 Put it on the car. 450 00:23:39,000 --> 00:23:41,000 All right. 451 00:23:41,000 --> 00:23:43,000 Now we wait? 452 00:23:43,000 --> 00:23:44,000 Now we wait. 453 00:23:44,000 --> 00:23:45,000 All right. 454 00:23:45,000 --> 00:23:48,000 Can we see any physical change in them? 455 00:23:48,000 --> 00:23:50,000 Now I don't see any change in them. 456 00:23:50,000 --> 00:23:53,000 Your dashboard's starting to melt though. 457 00:23:53,000 --> 00:23:56,000 I've been working in this area for about 30 years. 458 00:23:56,000 --> 00:24:00,000 I've never heard of this type of thing happening. 459 00:24:00,000 --> 00:24:04,000 But as you think about it, you've got the potential there. 460 00:24:04,000 --> 00:24:10,000 Because if you have enough heat, the pressure that's created by the gas inside 461 00:24:10,000 --> 00:24:14,000 can cause that container to pop. 462 00:24:14,000 --> 00:24:16,000 Come on. 463 00:24:16,000 --> 00:24:18,000 There we go. 464 00:24:19,000 --> 00:24:22,000 Do you think the flakies are going to go first or the buttermilks? 465 00:24:22,000 --> 00:24:25,000 The small one's going to go first because it has less mass. 466 00:24:25,000 --> 00:24:31,000 It's going to take at least probably a half an hour for the interior of those things 467 00:24:31,000 --> 00:24:34,000 to show hardly any change in temperature. 468 00:24:34,000 --> 00:24:36,000 Much less enough to work through. 469 00:24:36,000 --> 00:24:37,000 Yeah. 470 00:24:37,000 --> 00:24:39,000 I mean, it's too much mass. 471 00:24:39,000 --> 00:24:41,000 It's still going to be way less than 120 minutes. 472 00:24:41,000 --> 00:24:43,000 I'll find out. 473 00:24:43,000 --> 00:24:46,000 The leavening agent is sodium bicarbonate. 474 00:24:46,000 --> 00:24:54,000 And it is reacting with an acid to produce carbon dioxide CO2. 475 00:24:54,000 --> 00:24:59,000 If it is not released, you're going to create pressure in that container 476 00:24:59,000 --> 00:25:04,000 to the point where as the reaction continues, that container can burst. 477 00:25:05,000 --> 00:25:07,000 Whoa! 478 00:25:09,000 --> 00:25:12,000 Jamie, do you know what happened? 479 00:25:12,000 --> 00:25:13,000 What? 480 00:25:13,000 --> 00:25:15,000 It jumped out of the rack. 481 00:25:15,000 --> 00:25:17,000 That's the small can that was in the rack. 482 00:25:17,000 --> 00:25:20,000 It jumped out of the rack and into my cup holder. 483 00:25:20,000 --> 00:25:22,000 It'll all be done. 484 00:25:22,000 --> 00:25:25,000 And so where was our clock? Where were we at? 485 00:25:25,000 --> 00:25:28,000 We were at like 58 minutes on the nose. 486 00:25:28,000 --> 00:25:30,000 So you won the bet then? 487 00:25:30,000 --> 00:25:32,000 In fact, I did. 488 00:25:32,000 --> 00:25:36,000 I'd like to win that one before it bakes dough into my cup holder. 489 00:25:36,000 --> 00:25:39,000 Although I was right about which one was going to go first. 490 00:25:39,000 --> 00:25:41,000 You were absolutely right. 491 00:25:46,000 --> 00:25:48,000 Whoa! 492 00:25:49,000 --> 00:25:51,000 That was kind of spectacular. 493 00:25:51,000 --> 00:25:54,000 I mean, we're missing a whole tin. I don't even see it in there. 494 00:25:54,000 --> 00:25:56,000 Adam, which tin was it? 495 00:25:56,000 --> 00:25:59,000 That was the unrefrigerated. 496 00:25:59,000 --> 00:26:03,000 That was the unrefrigerated flaky dough. 497 00:26:05,000 --> 00:26:07,000 Well, now, there you go. 498 00:26:07,000 --> 00:26:10,000 I mean, it blew the top right off of that thing. 499 00:26:10,000 --> 00:26:13,000 That was the unrefrigerated leading brand. 500 00:26:13,000 --> 00:26:17,000 I mean, this is stupefyingly boring, but, you know, things are blowing up in my car. 501 00:26:17,000 --> 00:26:19,000 What could be better? 502 00:26:22,000 --> 00:26:24,000 Whoa! 503 00:26:24,000 --> 00:26:27,000 It's 137 degrees right now. 504 00:26:27,000 --> 00:26:31,000 Well, that seems to be the butter zone.

573 00:29:59,000 --> 00:30:02,000 Well, we're going to need a pane of glass. 574 00:30:02,000 --> 00:30:05,000 We've got to build a mock-up body. 575 00:30:05,000 --> 00:30:12,000 We have to create some sort of a track and a means of loading this dummy body. 576 00:30:12,000 --> 00:30:17,000 We'll probably use some of, I've got a bunch of surgical rubber tubing that we can make a big sling shot. 577 00:30:17,000 --> 00:30:18,000 Okay. 578 00:30:18,000 --> 00:30:24,000 And we'll have to also rig various ways of measuring, so we're consistent about it, 579 00:30:24,000 --> 00:30:26,000 how much force we're putting on him. 580 00:30:26,000 --> 00:30:32,000 Right, I mean the figure we want to come up with is whether or not it's possible for a person running at a reasonable clip 581 00:30:32,000 --> 00:30:37,000 into the window has enough pounds of force behind him to actually break the window. 582 00:30:39,000 --> 00:30:43,000 The first reaction is complete disbelief, and then the second reaction is, 583 00:30:43,000 --> 00:30:48,000 well I heard that happened in New York or Moscow or Hong Kong or something like that. 584 00:30:48,000 --> 00:30:53,000 It's just one of those stories that seems to have kind of gone around the world. 585 00:30:57,000 --> 00:31:01,000 First we need to decide what kind of track it is, whether we want. 586 00:31:01,000 --> 00:31:05,000 I'm thinking that we should roll it along the ground kind of track rather than hang it. 587 00:31:05,000 --> 00:31:09,000 You've got the great, the dolly track for the skateboard wheels. 588 00:31:09,000 --> 00:31:10,000 Okay. 589 00:31:10,000 --> 00:31:12,000 That's got a really low friction. 590 00:31:18,000 --> 00:31:21,000 I've only broken one bone in my body. 591 00:31:21,000 --> 00:31:23,000 My neck. 592 00:31:23,000 --> 00:31:26,000 So, how to build a lawyer. 593 00:31:26,000 --> 00:31:30,000 We're going to assume that this guy wasn't a fat cat. 594 00:31:30,000 --> 00:31:33,000 Make him say 160 pounds. 595 00:31:33,000 --> 00:31:35,000 Well they're going to be about, call him 20 pounds a piece. 596 00:31:35,000 --> 00:31:39,000 They're 20 pounds each, so it's going to be eight. 597 00:31:41,000 --> 00:31:51,000 Now I'm about to weld a steel frame that will hold up the sandbags to distribute their mass roughly like a person's body. 598 00:31:51,000 --> 00:31:58,000 These wooden blocks will stop our lawyer from falling backwards when he accelerates. 599 00:31:58,000 --> 00:32:03,000 But he'll be free to fall when the cart stops at the end of the track. 600 00:32:03,000 --> 00:32:04,000 Hey. 601 00:32:04,000 --> 00:32:09,000 On to the next task, finding the right pane of glass. 602 00:32:09,000 --> 00:32:13,000 Something that would be suitable for the 24th floor of a skyscraper. 603 00:32:13,000 --> 00:32:19,000 It's normally a thickness, which is greater than the thickness of the floor. 604 00:32:19,000 --> 00:32:23,000 It's greater than the thickness that you see in house glass. 605 00:32:23,000 --> 00:32:27,000 You're talking about six millimeter or ten millimeter. 606 00:32:27,000 --> 00:32:33,000 At three quarters of an inch, this four foot by eight foot pane seems to be the standard size. 607 00:32:33,000 --> 00:32:37,000 So we successfully have a piece of glass for the falling lawyer. 608 00:32:37,000 --> 00:32:38,000 Thanks. 609 00:32:40,000 --> 00:32:43,000 I think I'll build the frame out of just plywood. 610 00:32:43,000 --> 00:32:47,000 And we'll seal it up with some caulk just like we would in aquarium. 611 00:32:47,000 --> 00:32:53,000 And we may want to put the tempered glass in the front. 612 00:32:53,000 --> 00:32:55,000 Look at that. 613 00:32:57,000 --> 00:32:58,000 Ready? 614 00:32:58,000 --> 00:33:00,000 Yeah, okay. 615 00:33:00,000 --> 00:33:03,000 Whoa. Could have counted three. 616 00:33:03,000 --> 00:33:05,000 Glass comes in sealed units. 617 00:33:05,000 --> 00:33:09,000 And they're set into recesses in frames. 618 00:33:09,000 --> 00:33:13,000 So that they're supported around the total perimeter usually. 619 00:33:13,000 --> 00:33:16,000 Our frame won't just support the glass. 620 00:33:16,000 --> 00:33:22,000 It'll also allow us to reproduce some of the forces at work inside tall buildings. 621 00:33:22,000 --> 00:33:28,000 And then we also have to think of things like, you know, if there's pressure in the building 622 00:33:28,000 --> 00:33:34,000 or that would either tend to, you know, make things different. 623 00:33:34,000 --> 00:33:36,000 Inside of a building, there's a lot of things happening. 624 00:33:36,000 --> 00:33:40,000 There's mechanical equipment, which is exhausting air. 625 00:33:40,000 --> 00:33:44,000 And there's mechanical equipment, which is pushing air into the building. 626 00:33:44,000 --> 00:33:49,000 And if you don't get the same amount of air going out as you're pushing in 627 00:33:49,000 --> 00:33:52,000 then you start to build up pressures within the building. 628 00:33:52,000 --> 00:33:58,000 This stack effect is just 1.47 pounds per square inch. 629 00:33:58,000 --> 00:34:01,000 But we think that's going to be crucial. 630 00:34:01,000 --> 00:34:08,000 Because the glass has, you know, it's like 4,600 square inches, the amount of force, there's not much of a... 631 00:34:08,000 --> 00:34:13,000 Yeah, well you wouldn't think so, but it's a funny thing about pressures like that. 632 00:34:13,000 --> 00:34:18,000 When you're thinking in terms of PSIs and so on, it adds up. 633 00:34:18,000 --> 00:34:25,000 Even a very small fraction of a PSI times 4,600 starts to get into, you know, 1,000 pounds of air. 634 00:34:25,000 --> 00:34:27,000 Oh right, across the whole face of the glass. 635 00:34:27,000 --> 00:34:31,000 So it could have played a significant factor in the windows breaking on that particular day. 636 00:34:31,000 --> 00:34:37,000 4,600 pounds of pressure is definitely something we want to factor in. 637 00:34:37,000 --> 00:34:43,000 So that means that our frame that the window is going in actually has to be a chamber. 638 00:34:43,000 --> 00:34:50,000 Right, we'll seal it off in the back and we'll hook a vacuum or a pressure pump up to it. 639 00:34:53,000 --> 00:34:58,000 Jamie doesn't have a pump large enough to increase the air pressure in the shop. 640 00:34:58,000 --> 00:35:04,000 Instead, he'll reproduce the stack effect by sucking air out of the chamber. 641 00:35:07,000 --> 00:35:10,000 I can see the plexiglass falling. 642 00:35:10,000 --> 00:35:17,000 This pump is too powerful. It's threatening to rip the plexiglass out of the chamber. 643 00:35:17,000 --> 00:35:23,000 And our vacuum gauge isn't sensitive enough. 644 00:35:23,000 --> 00:35:30,000 You know what I think we should do is that we should just rig our own gauge in terms of inches of water. 645 00:35:30,000 --> 00:35:36,000 I believe inches of water is going to be a lot more sensitive than inches of mercury because it's a lot lighter. 646 00:35:36,000 --> 00:35:42,000 And then what mercury is, I mean it's literally we put a tube in there like a U-shaped tube. 647 00:35:42,000 --> 00:35:49,000 It's just like a barometer and that's the kind of scale that we're dealing with is like barometric pressure. 648 00:35:49,000 --> 00:35:55,000 It'll be an interesting thing for us. With a tube of water we'll get all the sensitivity we want. 649 00:35:57,000 --> 00:36:02,000 So it should be about 4 inches of water for the minimum. 650 00:36:02,000 --> 00:36:05,000 No, no, no. Oh, point 0.0. 651 00:36:05,000 --> 00:36:08,000 So you're right. That's magnificent. 652 00:36:08,000 --> 00:36:11,000 We've rigged this leaf blower to suck. 653 00:36:11,000 --> 00:36:16,000 Hooked up to a variable switch, it should also be easier on the plexiglass. 654 00:36:16,000 --> 00:36:19,000 There we go. 655 00:36:19,000 --> 00:36:22,000 Alright. You want it? Okay. 656 00:36:22,000 --> 00:36:24,000 I'll tell you when we're... let's sit here. 657 00:36:24,000 --> 00:36:25,000 Oh, look at that. 658 00:36:25,000 --> 00:36:28,000 Oh, that's beautiful. We got sensitivity, baby. 659 00:36:28,000 --> 00:36:31,000 Keep going. 660 00:36:31,000 --> 00:36:34,000 Little more, little more, little more. 661 00:36:34,000 --> 00:36:37,000 Scotty, I need power. 662 00:36:37,000 --> 00:36:39,000 Do you want more?

That's it. 0.145 negative PSI. 667 00:36:55,000 --> 00:36:58,000 We've proved the principle. 668 00:36:58,000 --> 00:37:05,000 Now, with the addition of some glass tube, a scale, and food dye, we have a working gauge. 669 00:37:05,000 --> 00:37:10,000 Mr. Savage, if I could suggest that you put a drop of the coloring in there first. 670 00:37:10,000 --> 00:37:15,000 No, I was thinking I'd put it in after and then I'd go and like, fix it up. 671 00:37:15,000 --> 00:37:17,000 Thought that would be kind of cool. 672 00:37:17,000 --> 00:37:18,000 Okay. 673 00:37:18,000 --> 00:37:23,000 With the stack effect problem solved, it's time to rig the slingshot. 674 00:37:24,000 --> 00:37:26,000 Grrr. 675 00:37:26,000 --> 00:37:32,000 We'll rig our slingshot somehow on, you know, we can tie to the side of the shop or something like that. 676 00:37:32,000 --> 00:37:33,000 Right. 677 00:37:36,000 --> 00:37:42,000 So I was thinking for, to figure out his velocity, to figure out how fast he's traveling, we don't have a radar gun or anything like that. 678 00:37:42,000 --> 00:37:46,000 I was thinking we could take some flats and actually grid them. 679 00:37:46,000 --> 00:37:47,000 Okay. 680 00:37:47,000 --> 00:37:54,000 We can shoot from the side with one of the cameras, which give us, you know, 25 frames per second. 681 00:37:54,000 --> 00:37:57,000 And then we can, you know, slow them out through the tape. 682 00:37:57,000 --> 00:38:02,000 We can frame by frame through the tape and see exactly how fast that he's traveling. 683 00:38:03,000 --> 00:38:06,000 Finally, everything's in place. 684 00:38:09,000 --> 00:38:11,000 Three yards, that's my bet. 685 00:38:12,000 --> 00:38:14,000 I guess that it's going to go five yards. 686 00:38:14,000 --> 00:38:15,000 Five yards?
