302 00:15:11,000 --> 00:15:15,000 Very simply because a dimple golf ball travels further than a smooth one. 303 00:15:15,000 --> 00:15:20,000 If we had a smooth ball, this laminar boundary layer tends to leave the surface at the location of the apex of the ball. 304 00:15:20,000 --> 00:15:26,000 This creates a separated region behind the ball, which we call a wake, and that means high drag. 305 00:15:26,000 --> 00:15:32,000 Now if we dimple the ball, then the dimples will make that laminar boundary layer turbulent, 306 00:15:32,000 --> 00:15:34,000 and thereby make it more energetic. 307 00:15:34,000 --> 00:15:38,000 It's able to stay attached to the surface for a longer period. 308 00:15:38,000 --> 00:15:41,000 Therefore, your laying separation is smaller wake, less drag. 309 00:15:41,000 --> 00:15:45,000 So just how much of a difference do those dimples make? 310 00:15:45,000 --> 00:15:51,000 For a top-notch drive, the mythbusters have enlisted pro golfer William Lin. 311 00:15:52,000 --> 00:15:56,000 William alternates between driving the regular and smooth balls. 312 00:15:56,000 --> 00:16:00,000 I claim this golf ball is the name of mythbusters. 313 00:16:00,000 --> 00:16:06,000 The only difference being the dimpling. In every other respect, they're identical. 314 00:16:06,000 --> 00:16:08,000 The smooth one feels like hitting a brick. 315 00:16:08,000 --> 00:16:10,000 I swapped it out when you weren't looking. 316 00:16:10,000 --> 00:16:13,000 Well, first of all, William, nice shooting. 317 00:16:13,000 --> 00:16:14,000 Thank you. 318 00:16:14,000 --> 00:16:16,000 These are all really tightly clustered. 319 00:16:16,000 --> 00:16:19,000 But you'll notice the smooth balls are all here. 320 00:16:19,000 --> 00:16:22,000 Dimpled balls way down that way. 321 00:16:22,000 --> 00:16:24,000 Looks almost twice as far to me. 322 00:16:24,000 --> 00:16:26,000 Yeah, at least. 323 00:16:26,000 --> 00:16:28,000 It's clear those dimples make a huge difference. 324 00:16:28,000 --> 00:16:29,000 I'll be darned. 325 00:16:29,000 --> 00:16:32,000 And just how much of a difference? 326 00:16:32,000 --> 00:16:35,000 Smooth balls, 556 feet. 327 00:16:37,000 --> 00:16:41,000 Dimpled balls, 893 feet. 328 00:16:41,000 --> 00:16:46,000 That's an average of 37% further for the dimpled balls. 329 00:16:46,000 --> 00:16:50,000 The dimples obviously work. I'd like to have a closer look at why. 330 00:16:50,000 --> 00:16:52,000 Yeah, me too. 331 00:16:52,000 --> 00:16:59,000 So to get a bead on exactly how the simple dimple works, the guys are going to need bigger balls. 332 00:16:59,000 --> 00:17:02,000 We need to have a closer look at the aerodynamics of a golf ball. 333 00:17:02,000 --> 00:17:04,000 And to do that, we're going to put it in a wind tunnel. 334 00:17:04,000 --> 00:17:08,000 Now, these balls are kind of small to have a nice look at it. 335 00:17:08,000 --> 00:17:14,000 So I'm going to take this bowling ball and give it dimples like what are on here to scale. 336 00:17:14,000 --> 00:17:17,000 Then we ought to be able to see it clearly. 337 00:17:17,000 --> 00:17:19,000 But while Jamie's going big scale... 338 00:17:19,000 --> 00:17:24,000 Okay, here's the first 360 holes. 339 00:17:24,000 --> 00:17:27,000 Adam's going the opposite way. 340 00:17:27,000 --> 00:17:34,000 So the fact that this effect works so well on a golf ball may mean that it has some application to a full-size automobile. 341 00:17:34,000 --> 00:17:38,000 But we're not going to start dimpling this full-size car just yet. 342 00:17:38,000 --> 00:17:40,000 Now, we're going to work in scale. 343 00:17:40,000 --> 00:17:44,000 And that's where this polycarbonate car will actually come into play. 344 00:17:44,000 --> 00:17:46,000 I'm going to make two castings out of it in resin. 345 00:17:46,000 --> 00:17:49,000 One of which I will dimple, one of which I will not. 346 00:17:49,000 --> 00:17:54,000 And hopefully in the comparison between those two, I might see some of the improvement that I'm looking for. 347 00:17:54,000 --> 00:17:58,000 It's done. It's perfect. 348 00:17:59,000 --> 00:18:02,000 Three hours of drilling holes. 349 00:18:03,000 --> 00:18:06,000 Eventually the models are ready for their close-up. 350 00:18:06,000 --> 00:18:09,000 Well, we've got some questions about smoothness and dimples. 351 00:18:09,000 --> 00:18:15,000 And hopefully here at the Fluid Mechanics Lab at NASA Ames Research Center, we'll find the answers that we're looking for. 352 00:18:15,000 --> 00:18:18,000 Hey Curtis, we've got some extra large golf balls for testing. 353 00:18:18,000 --> 00:18:21,000 Ah, fantastic. Why don't we get to work putting these in the wind tunnel? 354 00:18:21,000 --> 00:18:22,000 All right. 355 00:18:25,000 --> 00:18:26,000 Start it up. 356 00:18:27,000 --> 00:18:32,000 Can you really see the area behind the ball? It's like a bubble. 357 00:18:32,000 --> 00:18:36,000 Yeah, really clear how much is happening back in there. 358 00:18:36,000 --> 00:18:39,000 And once both balls have been exposed... 359 00:18:39,000 --> 00:18:41,000 That's pretty cool. I want to see the high speed. 360 00:18:41,000 --> 00:18:42,000 Yeah. 361 00:18:42,000 --> 00:18:44,000 The high speed tells the tale. 362 00:18:44,000 --> 00:18:47,000 Traces smoke patterns from both the smooth and the dimpled ball. 363 00:18:47,000 --> 00:18:50,000 And it's really clear the dimpled ball is making much less of a wake. 364 00:18:50,000 --> 00:18:53,000 It's expending less energy dragging that bubble around. 365 00:18:53,000 --> 00:18:56,000 Which is why it'll travel farther. 366 00:18:56,000 --> 00:19:03,000 The chaotic boundary layer on the dimpled ball created a smaller wake and therefore less drag. 367 00:19:03,000 --> 00:19:08,000 The only question we've now got to answer is, will this effect translate to the shape of a car? 368 00:19:08,000 --> 00:19:11,000 Well, that's a perfect segue to the next sequence. 369 00:19:11,000 --> 00:19:13,000 Almost too perfect. 370 00:19:13,000 --> 00:19:15,000 This thing right here is a water channel. 371 00:19:15,000 --> 00:19:21,000 And the water in it is moving about an inch a second, which allows us to inject fluorescent die streams into it 372 00:19:21,000 --> 00:19:25,000 so we can have a close look at flow patterns around various objects. 373 00:19:25,000 --> 00:19:30,000 Now, given that we're dealing with aerodynamics, why are we using water? 374 00:19:30,000 --> 00:19:34,000 Well, because technically water and air are both fluids. 375 00:19:34,000 --> 00:19:37,000 And for our purposes, they behave the same way. 376 00:19:37,000 --> 00:19:42,000 Well, that's a good thing because Adam's already got the smooth car immersed. 377 00:19:42,000 --> 00:19:44,000 Beauty. Look at that. 378 00:19:44,000 --> 00:19:46,000 I'll turn on the die. 379 00:19:46,000 --> 00:19:47,000 Alright. 380 00:19:47,000 --> 00:19:50,000 Wow, that is so beautiful. 381 00:19:50,000 --> 00:19:54,000 So that dead zone behind the car, that's what's slowing it down, right? 382 00:19:54,000 --> 00:19:58,000 Yeah, that's the wake and the smaller it is, the better off we are as far as mileage. 383 00:19:58,000 --> 00:20:03,000 And once some red dye is added, the static wake is even clearer. 384 00:20:03,000 --> 00:20:06,000 Ah, look at that. 385 00:20:06,000 --> 00:20:09,000 That is so cool. It's just sticking there. 386 00:20:09,000 --> 00:20:12,000 But how will the dimpled car compare? 387 00:20:12,000 --> 00:20:16,000 Okay, that's interesting. It looks like it starts at the same point on the car, but look at the green lines. 388 00:20:16,000 --> 00:20:21,000 They look like they're hugging closer. It looks like that bubble is smaller. 389 00:20:21,000 --> 00:20:26,000 It could be narrower, but to be accurate, we should look at the two images side by side. 390 00:20:26,000 --> 00:20:29,000 Well, it's funny you mentioned that, Jamie, because... 391 00:20:29,000 --> 00:20:34,000 Now, through the magic of post-production, I want to show you each of the cars in its water channel tests. 392 00:20:34,000 --> 00:20:37,000 Here's the smooth car. Here's the dimpled car. 393 00:20:37,000 --> 00:20:40,000 Hold on. I'm going to leave frame so you can see them both as big as possible. 394 00:20:40,000 --> 00:20:41,000 Look at that. 395 00:20:41,000 --> 00:20:49,000 I don't know about you, but it seems subtle, but still somewhat there, that the dimpled car has a smaller wake. 396 00:20:49,000 --> 00:20:54,000 Does that mean that it's more fuel efficient? The only way to tell is for us to go full scale. 397 00:20:54,000 --> 00:20:57,000 But that's not going to be a walk in the park. 398 00:20:57,000 --> 00:21:00,000 For that, they'll need to get a little creative. 399 00:21:02,000 --> 00:21:04,000 Next, our hangover guinea pigs... 400 00:21:04,000 --> 00:21:06,000 Everything hurts right now, though. 401 00:21:06,000 --> 00:21:09,000 ...are suffering in science. 402 00:21:12,000 --> 00:21:15,000 Beer. 403 00:21:15,000 --> 00:21:18,000 Supposedly the nectar of the gods. 404 00:21:18,000 --> 00:21:23,000 It's the world's oldest and most widely consumed alcoholic beverage. 405 00:21:23,000 --> 00:21:29,000 But does a night on the amber liquid leave you in a better state the morning after than mixing your drinks? 406 00:21:29,000 --> 00:21:35,000 With their hangover free baseline done and dusted, it's time to wet the whistle. 407 00:21:35,000 --> 00:21:37,000 Alright, time for science. 408 00:21:37,000 --> 00:21:39,000 Finally, we can start drinking. 409 00:21:39,000 --> 00:21:40,000 Alright, so what's the deal? 410 00:21:40,000 --> 00:21:46,000 I'm going to keep track of how many beers you guys drink, drink as many as you think it's going to take for you guys to get hangovers, 411 00:21:46,000 --> 00:21:51,000 and we'll have the same amount of alcohol when we do the beer mixing with the spirits. 412 00:21:51,000 --> 00:21:56,000 With Carrie keeping track, the boys don't waste any time beer-ing up. 413 00:21:56,000 --> 00:21:58,000 Check this out. 414 00:21:58,000 --> 00:22:04,000 I don't always drink beer, but when I do, I prefer mythbusters. 415 00:22:04,000 --> 00:22:07,000 Because the goal of this experiment... 416 00:22:07,000 --> 00:22:09,000 Can't get another round of science from me and my buddy here. 417 00:22:09,000 --> 00:22:12,000 ...is drinking enough to get hungover. 418 00:22:12,000 --> 00:22:14,000 Hey, darling, can I get another one? 419 00:22:14,000 --> 00:22:16,000 Something they're not happy about. 420 00:22:16,000 --> 00:22:17,000 Beer. 421 00:22:17,000 --> 00:22:20,000 We're not even that far in. 422 00:22:20,000 --> 00:22:23,000 I know, but science ain't pretty. 423 00:22:23,000 --> 00:22:27,000 Remember, Tory and Grant don't need to drink the same amount as each other. 424 00:22:27,000 --> 00:22:34,000 The crucial thing is that they drink the same volume of alcohol for this test and the mixed drinks test. 425 00:22:34,000 --> 00:22:36,000 Touch your nose with your left hand. 426 00:22:36,000 --> 00:22:38,000 Very good. 427 00:22:38,000 --> 00:22:40,000 Now with your right. 428 00:22:40,000 --> 00:22:44,000 After a solid session of 11 beers for Tory and five for Grant, 429 00:22:44,000 --> 00:22:48,000 it's clear that tomorrow morning is going to be bad. 430 00:22:48,000 --> 00:22:53,000 Okay, so they've had enough beers to get them sufficiently hungover for tomorrow. 431 00:22:53,000 --> 00:22:54,000 Not even close. 432 00:22:54,000 --> 00:22:56,000 Almost. 433 00:22:57,000 --> 00:23:00,000 So I'm going to leave the EMT in charge. 434 00:23:00,000 --> 00:23:03,000 I'm going to go home and get a good night's sleep. 435 00:23:03,000 --> 00:23:07,000 Make sure they don't hurt themselves, Kevin. 436 00:23:07,000 --> 00:23:14,000 At midnight with the final beer tally at 14 for Tory and six for Grant, they turn in. 437 00:23:14,000 --> 00:23:21,000 Hopefully, in the best case scenario, I have a hangover and I'm ready to test tomorrow morning, 438 00:23:21,000 --> 00:23:24,000 which is going to suck. 439 00:23:25,000 --> 00:23:26,000 Good night. 440 00:23:26,000 --> 00:23:33,000 And just like the control, after six hours of peaceful slumber, Carrie returns. 441 00:23:34,000 --> 00:23:36,000 Rise and shine. 442 00:23:37,000 --> 00:23:39,000 It's morning time. 443 00:23:41,000 --> 00:23:43,000 Good morning, Mythbusters. 444 00:23:44,000 --> 00:23:47,000 There's no denying that the boys are hungover. 445 00:23:48,000 --> 00:23:51,000 Ugh, everything hurts right now though. 446 00:23:56,000 --> 00:24:00,000 It is physically throbbing.

518 00:28:42,000 --> 00:28:45,000 Well, there did seem to be a small effect in the water tunnel. 519 00:28:45,000 --> 00:28:47,000 Right, well, you know what that means. 520 00:28:47,000 --> 00:28:48,000 No, what? 521 00:28:48,000 --> 00:28:52,000 Well, if there was a small effect on the small scale car. 522 00:28:52,000 --> 00:28:56,000 It follows that there would be a big effect on a bigger car. 523 00:28:56,000 --> 00:28:59,000 Right, if we're going to find out whether or not that's true, we need to go full scale with this thing. 524 00:28:59,000 --> 00:29:00,000 I'm there. 525 00:29:00,000 --> 00:29:02,000 But that ain't going to be easy. 526 00:29:02,000 --> 00:29:08,000 How exactly do you dimple a full scale car without ruining it? 527 00:29:08,000 --> 00:29:13,000 So this 1,000 pounds of clay is hopefully our solution to dimpling this car. 528 00:29:13,000 --> 00:29:19,000 In order to do that, we need to start by covering the entire body in a perfectly even layer of clay. 529 00:29:19,000 --> 00:29:23,000 So we went to the automotive design department of a local design college 530 00:29:23,000 --> 00:29:27,000 and conscripted some of the students to assist us in this endeavor. 531 00:29:27,000 --> 00:29:29,000 We're going to set up a whole assembly line. 532 00:29:29,000 --> 00:29:32,000 Some people are going to be cutting slabs of clay all the same thickness. 533 00:29:32,000 --> 00:29:33,000 Some people are going to be applying it. 534 00:29:33,000 --> 00:29:36,000 Some people are going to be smoothing the clay that's already applied. 535 00:29:36,000 --> 00:29:43,000 And hopefully by the end of the day, we're going to have a car that looks just like this, except this color. 536 00:29:43,000 --> 00:29:47,000 Right, well, with the clay nation in motion, it won't be long. 537 00:29:47,000 --> 00:29:49,000 But why clay? 538 00:29:49,000 --> 00:29:55,000 We decided to use clay on this car because actually dimpling the car is rather difficult. 539 00:29:55,000 --> 00:30:02,000 An impact on the sheet metal of the car would make a big cavity rather than just a nice little divot. 540 00:30:02,000 --> 00:30:08,000 The divots we can do on the clay and that'll happen after we do the task with it smooth. 541 00:30:08,000 --> 00:30:11,000 And that's a whole lot of smoothing. 542 00:30:11,000 --> 00:30:13,000 But eventually... 543 00:30:13,000 --> 00:30:19,000 Six guys, 850 pounds of clay and six hours later, we've got a control car. 544 00:30:19,000 --> 00:30:24,000 Indeed, but the weight of the clay will likely lower the car's fuel efficiency. 545 00:30:24,000 --> 00:30:30,000 So before any dimpling begins, they'll need a new control with its smooth mileage. 546 00:30:30,000 --> 00:30:34,000 Here I am back at the start line of our one-mile test track. 547 00:30:34,000 --> 00:30:36,000 At the other end, I've got a car covered in clay. 548 00:30:36,000 --> 00:30:40,000 I'm going to run it several times down this track smooth. 549 00:30:40,000 --> 00:30:46,000 Then I'm going to carve some golf ball-like dimples into its surface and do several more runs. 550 00:30:46,000 --> 00:30:53,000 This test ought to answer once and for all whether golf ball-like dimples in a car makes it more fuel efficient. 551 00:30:53,000 --> 00:30:57,000 Great, but this time they're doing things slightly different. 552 00:30:57,000 --> 00:30:59,000 This is going to be our test procedure. 553 00:30:59,000 --> 00:31:07,000 We've replaced the window-mounted gas tank with a trunk-mounted fuel cell, which we will weigh before we do the test. 554 00:31:07,000 --> 00:31:09,000 10.056 kilograms of fuel. 555 00:31:09,000 --> 00:31:15,000 We'll get up to 65 miles per hour using our regular fuel tank, and when we hit the start line... 556 00:31:15,000 --> 00:31:16,000 Right here! 557 00:31:16,000 --> 00:31:18,000 ...we'll switch to the fuel cell. 558 00:31:18,000 --> 00:31:20,000 When we cross the finish line... 559 00:31:20,000 --> 00:31:22,000 One mile later... 560 00:31:22,000 --> 00:31:31,000 ...we turn off the fuel cell, we weigh it again, and then we determine the miles per gallon by the drop in weight of the fuel cell. 561 00:31:31,000 --> 00:31:35,000 And with that sorted, it's go time for the smooth car. 562 00:31:35,000 --> 00:31:37,000 You ready to do some driving?
