Starting gun test in three, two, one. 304 00:14:51,680 --> 00:14:55,680 From the get-go, it's clear that Jamie's semi-auto is fast, 305 00:14:55,680 --> 00:14:59,680 but it's not fast enough to let him shoot his way out of trouble. 306 00:15:00,680 --> 00:15:01,680 I'm down. 307 00:15:03,680 --> 00:15:05,680 It's time. I don't think he got four minutes. 308 00:15:06,680 --> 00:15:10,680 In total, Jamie manages only seven kills, one less than Adam. 309 00:15:11,680 --> 00:15:13,680 One of my favorite things about this show, 310 00:15:13,680 --> 00:15:16,680 one of the most scientific things that we do is we take feedback 311 00:15:16,680 --> 00:15:19,680 after episodes have aired and we go back and re-retest things. 312 00:15:19,680 --> 00:15:21,680 I love that. 313 00:15:21,680 --> 00:15:23,680 Fans did not like my axe technique, 314 00:15:23,680 --> 00:15:26,680 so we rejiggered it, made my axe much more realistic to swing, 315 00:15:26,680 --> 00:15:31,680 and as expected, that radically reduced the number of zombies that I could kill. 316 00:15:32,680 --> 00:15:34,680 But I thought that Jamie was going to mop the floor with me 317 00:15:34,680 --> 00:15:37,680 with his use of his new semi-auto paintball pistol, 318 00:15:38,680 --> 00:15:42,680 and yet he didn't improve his score at all. 319 00:15:42,680 --> 00:15:46,680 I am totally gobsmacked that it seems right now 320 00:15:47,680 --> 00:15:50,680 like axe versus gun, it's axe. 321 00:15:53,680 --> 00:15:54,680 Oh, yeah. 322 00:15:55,680 --> 00:15:59,680 Yep, despite the slowdown, the axe is ahead by a head. 323 00:16:01,680 --> 00:16:04,680 But there's way more to come for our armchair army. 324 00:16:04,680 --> 00:16:05,680 I'm ready. 325 00:16:09,680 --> 00:16:12,680 But only after some retail therapy. 326 00:16:12,680 --> 00:16:15,680 And we are pretty much done. 327 00:16:15,680 --> 00:16:19,680 Five checkout stands each with working cash registers and indicator lights. 328 00:16:19,680 --> 00:16:24,680 Five thousand separate food items are rated on over 750 feet of shelving, 329 00:16:24,680 --> 00:16:26,680 every single one with its own label. 330 00:16:26,680 --> 00:16:30,680 $56,000 in play, myth busters, money. 331 00:16:30,680 --> 00:16:35,680 This is without a doubt the most elaborate experimental setup we have ever implemented, 332 00:16:35,680 --> 00:16:38,680 all to find out which is the more efficient way to wait online. 333 00:16:38,680 --> 00:16:40,680 Now we are pretty much ready to go, 334 00:16:40,680 --> 00:16:42,680 we just got to make sure that everything is properly priced. 335 00:16:42,680 --> 00:16:45,680 This one doesn't have a price, that's a problem. 336 00:16:45,680 --> 00:16:51,680 The guys are testing whether the traditional picolain method is really slower than one long line, 337 00:16:51,680 --> 00:16:54,680 known in the trade as the Serpentine. 338 00:16:56,680 --> 00:16:59,680 And with their 5,000 products all priced, 339 00:17:00,680 --> 00:17:03,680 their elaborate plan is ready to be revealed. 340 00:17:04,680 --> 00:17:06,680 Here's how this experimental setup works. 341 00:17:06,680 --> 00:17:09,680 We've got 120 volunteers and they will enter the store 342 00:17:09,680 --> 00:17:13,680 where they'll receive a shopping list of exactly how many items we want them to buy. 343 00:17:13,680 --> 00:17:14,680 Then they'll go get a cart. 344 00:17:15,680 --> 00:17:17,680 Once they have their cart, they'll enter the store 345 00:17:17,680 --> 00:17:20,680 and choose from the vast selection of myth busters merchandise on display. 346 00:17:20,680 --> 00:17:22,680 Personally, I hope we get cookies. 347 00:17:23,680 --> 00:17:25,680 Once our customer gets in line for the cashier, 348 00:17:25,680 --> 00:17:27,680 that's when the data collection actually begins. 349 00:17:27,680 --> 00:17:32,680 They will pull out their timestamp card and enter the precise moment they got in line. 350 00:17:32,680 --> 00:17:35,680 Then they'll proceed right towards the cashier. 351 00:17:35,680 --> 00:17:37,680 Once our customer reaches the cashier, 352 00:17:37,680 --> 00:17:39,680 that's when they enter the second data point, 353 00:17:39,680 --> 00:17:41,680 the time they got to the checkout stand. 354 00:17:41,680 --> 00:17:44,680 Thus we will have the precise length of time 355 00:17:44,680 --> 00:17:46,680 they spend waiting in line. 356 00:17:47,680 --> 00:17:49,680 Our last stop is here, data collection, 357 00:17:49,680 --> 00:17:52,680 where we not only gather our customers' timestamps, 358 00:17:52,680 --> 00:17:54,680 but we're also interested in their experience. 359 00:17:54,680 --> 00:17:56,680 So on the back of each time card, 360 00:17:56,680 --> 00:17:59,680 they will grade their overall satisfaction with the line. 361 00:18:01,680 --> 00:18:04,680 With five experienced register operators 362 00:18:05,680 --> 00:18:08,680 and a stats table staffed by experts, 363 00:18:09,680 --> 00:18:11,680 everything set to release the volunteers 364 00:18:11,680 --> 00:18:14,680 for first a full systems check. 365 00:18:15,680 --> 00:18:16,680 All right shoppers, 366 00:18:16,680 --> 00:18:20,680 starting in three, two, one, go for the run through. 367 00:18:24,680 --> 00:18:26,680 I felt a little moment of pride 368 00:18:26,680 --> 00:18:28,680 that we just opened our first business 369 00:18:28,680 --> 00:18:30,680 and we've got all these customers. 370 00:18:32,680 --> 00:18:34,680 The guys are starting with a trial run 371 00:18:34,680 --> 00:18:37,680 to make sure their newly built store can cope, 372 00:18:37,680 --> 00:18:39,680 which at first it can. 373 00:18:39,680 --> 00:18:42,680 And the total comes to $9. 374 00:18:43,680 --> 00:18:45,680 But ten minutes later, 375 00:18:45,680 --> 00:18:48,680 the lines have become unrealistically long. 376 00:18:48,680 --> 00:18:51,680 We're already seeing some problems with our experimental design 377 00:18:51,680 --> 00:18:56,680 because our entire customer base ended up in long lines 378 00:18:56,680 --> 00:18:59,680 and that's not realistically like what we would have in a store. 379 00:18:59,680 --> 00:19:02,680 So we're going to have to figure out some way 380 00:19:02,680 --> 00:19:04,680 of pacing things a little bit 381 00:19:04,680 --> 00:19:07,680 to get lines that are more realistically sized 382 00:19:07,680 --> 00:19:09,680 to what you would see in a supermarket. 383 00:19:09,680 --> 00:19:12,680 Yep, with just too many shoppers, 384 00:19:12,680 --> 00:19:15,680 all at once, their commercial space can't cope. 385 00:19:15,680 --> 00:19:19,680 So the guys kick out their customers and reset. 386 00:19:19,680 --> 00:19:23,680 All right shoppers, commence entering the store. 387 00:19:24,680 --> 00:19:27,680 This time with 25% fewer people. 388 00:19:27,680 --> 00:19:30,680 There's a special on Jamie's Untiled Ford. 389 00:19:31,680 --> 00:19:34,680 Which soon results in cues that are much more realistic. 390 00:19:34,680 --> 00:19:37,680 Jamie, this is working beautifully. 391 00:19:37,680 --> 00:19:40,680 Meaning that the testing can shortly begin. 392 00:19:40,680 --> 00:19:43,680 We have done countless destructive stories over the years, 393 00:19:43,680 --> 00:19:45,680 but I also love myths like this one. 394 00:19:45,680 --> 00:19:47,680 I mean, I think when we do something like this, 395 00:19:47,680 --> 00:19:49,680 we might make the world a slightly better place 396 00:19:49,680 --> 00:19:51,680 by improving people's shopping experience. 397 00:19:51,680 --> 00:19:52,680 That's cool. 398 00:19:52,680 --> 00:19:55,680 That doesn't mean there can't be any destruction like this. 399 00:19:55,680 --> 00:19:57,680 Clean up on aisle 5. 400 00:20:08,680 --> 00:20:11,680 The Mythbusters have helped drivers save dollars. 401 00:20:11,680 --> 00:20:15,680 The dimpled car, 29.65 miles to the gallon. 402 00:20:15,680 --> 00:20:18,680 And revealed ways to save lives. 403 00:20:18,680 --> 00:20:20,680 It's going down. 404 00:20:20,680 --> 00:20:21,680 Oh boy. 405 00:20:21,680 --> 00:20:26,680 In fact, they've always armed viewers with important information. 406 00:20:26,680 --> 00:20:29,680 Did you know what was lurking in your basement? 407 00:20:31,680 --> 00:20:34,680 But at an apocalyptic warehouse, 408 00:20:34,680 --> 00:20:38,680 let's hope this myth's strange stats aren't ever needed. 409 00:20:38,680 --> 00:20:40,680 So where do we stand? 410 00:20:40,680 --> 00:20:42,680 Well, so far it still looks like 411 00:20:42,680 --> 00:20:46,680 Axe is edging out gun as a method for dispatching zombies. 412 00:20:46,680 --> 00:20:50,680 However, our testing scenario where zombies are coming from all sides, 413 00:20:50,680 --> 00:20:55,680 that is genuinely like the worst possible case scenario 414 00:20:55,680 --> 00:20:57,680 under which you could encounter zombies. 415 00:20:57,680 --> 00:21:00,680 In movies, it's much more likely that they're like trying to get in 416 00:21:00,680 --> 00:21:04,680 and they get through something, like a breach or a doorway. 417 00:21:04,680 --> 00:21:07,680 So that is the scenario we're going to set up next. 418 00:21:07,680 --> 00:21:10,680 It may sound like an oxymoron, 419 00:21:10,680 --> 00:21:14,680 but the guys are trying to up the realism of their zombie methodology. 420 00:21:14,680 --> 00:21:15,680 Nice. 421 00:21:15,680 --> 00:21:19,680 To do that, they're ditching the circle surround test 422 00:21:19,680 --> 00:21:22,680 and going instead with the classic fence breach. 423 00:21:23,680 --> 00:21:24,680 Keep out. 424 00:21:27,680 --> 00:21:31,680 The question is, will the axe still be the winning weapon? 425 00:21:35,680 --> 00:21:39,680 Three, two, one. 426 00:21:43,680 --> 00:21:48,680 Like film folklore, the undead start by coming through one by one. 427 00:21:49,680 --> 00:21:50,680 This is working great. 428 00:21:50,680 --> 00:21:57,680 But what Adam doesn't know is that Jamie's about to release the zombies en masse. 429 00:21:57,680 --> 00:21:58,680 Reaching the fence. 430 00:21:59,680 --> 00:22:00,680 Oh no! 431 00:22:01,680 --> 00:22:04,680 With walkers now pouring forward. 432 00:22:05,680 --> 00:22:06,680 A living wall! 433 00:22:07,680 --> 00:22:10,680 Adam's swing frequency has to rapidly rise, 434 00:22:12,680 --> 00:22:15,680 which causes him to get fatigued fast. 435 00:22:16,680 --> 00:22:23,680 So much so that the power of his swing starts to fall below the kill threshold. 436 00:22:25,680 --> 00:22:30,680 Adam is about exhausted and he's slowly losing the battle. 437 00:22:34,680 --> 00:22:35,680 This is exhausting. 438 00:22:41,680 --> 00:22:42,680 I'm dead. 439 00:22:46,680 --> 00:22:50,680 That was the hardest thing I've done in a long time. 440 00:22:51,680 --> 00:22:53,680 Looks like that was quite the workout. 441 00:22:54,680 --> 00:22:56,680 While Adam recovers, I might have pulled a muscle. 442 00:22:57,680 --> 00:22:59,680 Jamie counts up the dead. 443 00:22:59,680 --> 00:23:01,680 21, 22, 23, 24. 444 00:23:02,680 --> 00:23:04,680 To reveal a final tally that's terrifying. 445 00:23:05,680 --> 00:23:06,680 66, 67. 446 00:23:07,680 --> 00:23:11,680 Might be another body or so buried under there, but I'll call it 67. 447 00:23:12,680 --> 00:23:13,680 67, Tommy. 448 00:23:16,680 --> 00:23:17,680 67, Tommy. 449 00:23:19,680 --> 00:23:25,680 With 67, the benchmark to beat, it's time for Jamie to come out all guns blazing. 450 00:23:28,680 --> 00:23:29,680 I'm ready. 451 00:23:30,680 --> 00:23:33,680 Arm to the teeth and then some. 452 00:23:33,680 --> 00:23:35,680 You want a piece of me? 453 00:23:35,680 --> 00:23:37,680 That the carnage commenced. 454 00:23:37,680 --> 00:23:42,680 Please remember zombies that Jamie's flesh comes from Indiana, 455 00:23:42,680 --> 00:23:44,680 which means it's especially tasty. 456 00:23:47,680 --> 00:23:48,680 All right, here we go. 457 00:23:48,680 --> 00:23:51,680 In three, two, one. 458 00:23:53,680 --> 00:23:54,680 From the get go. 459 00:23:56,680 --> 00:23:57,680 He's not even moving. 460 00:23:58,680 --> 00:24:04,680 Jamie has a clear advantage over Adam as he takes down zombies on both sides of the fence. 461 00:24:08,680 --> 00:24:10,680 But when the fence gets breached, 462 00:24:11,680 --> 00:24:14,680 Jamie must really start firing on all cylinders. 463 00:24:20,680 --> 00:24:21,680 Excellent. 464 00:24:22,680 --> 00:24:23,680 He's doing good. 465 00:24:26,680 --> 00:24:27,680 Come on, Jamie, you can do it. 466 00:24:28,680 --> 00:24:32,680 Jamie may not be tiring, but the odd gun jam is slowing him down. 467 00:24:33,680 --> 00:24:35,680 Oh, he's going to run around the whole other side of this. 468 00:24:35,680 --> 00:24:36,680 This is kind of great. 469 00:24:36,680 --> 00:24:40,680 So much so that his days in the land of the living are numbered. 470 00:24:42,680 --> 00:24:43,680 He might be dead. 471 00:24:43,680 --> 00:24:44,680 Calm down. 472 00:24:49,680 --> 00:24:53,680 Jamie's dead and buried, but did he shoot more than 67? 473 00:24:53,680 --> 00:24:54,680 Mr. Heidemann. 474 00:24:54,680 --> 00:24:55,680 Yes. 475 00:24:55,680 --> 00:24:56,680 Stand up. 476 00:24:59,680 --> 00:25:01,680 He took 57 zombies with you. 477 00:25:02,680 --> 00:25:04,680 Well, I guess Axe beats gun, huh? 478 00:25:04,680 --> 00:25:05,680 That's fascinating. 479 00:25:05,680 --> 00:25:06,680 I would not have called that. 480 00:25:06,680 --> 00:25:07,680 All right, let's clean up this mess. 481 00:25:10,680 --> 00:25:11,680 All I got to say, I was surprised. 482 00:25:11,680 --> 00:25:14,680 You would think that this would be like shooting fish in a barrel, 483 00:25:14,680 --> 00:25:18,680 but these guns are more complex than something like an axe. 484 00:25:18,680 --> 00:25:19,680 They have to be reloaded. 485 00:25:19,680 --> 00:25:24,680 They can jam, and a second or two is enough to make everything go haywire. 486 00:25:24,680 --> 00:25:30,680 So I ended up scoring less than Adam, but I was expecting exactly the opposite. 487 00:25:30,680 --> 00:25:33,680 Yep, it's a result to confound the critics. 488 00:25:33,680 --> 00:25:38,680 When the apocalypse comes, folks, Axe does beat gun, and then some. 489 00:25:38,680 --> 00:25:43,680 After beating Jamie twice, both in the round and in the breach test, 490 00:25:43,680 --> 00:25:47,680 I'm like, damn, Axe, you are the proper tool. 491 00:25:47,680 --> 00:25:52,680 Mwah, not only good for a quest through Middle Earth, but also good against zombies. 492 00:25:54,680 --> 00:26:01,680 But before disbanding their undead army, there's one more zombie request to test. 493 00:26:01,680 --> 00:26:02,680 Groovy. 494 00:26:04,680 --> 00:26:09,680 Meanwhile, back at MythBus stores... 495 00:26:09,680 --> 00:26:13,680 Our employee of the month is James Franklin Heinemann. 496 00:26:13,680 --> 00:26:15,680 He hails from Columbus, Indiana. 497 00:26:15,680 --> 00:26:21,680 The lineup trial run has been such a success that the data collection can now begin. 498 00:26:21,680 --> 00:26:24,680 All right, timer ready? 499 00:26:24,680 --> 00:26:25,680 Here we go. 500 00:26:25,680 --> 00:26:27,680 Commence shopping test. 501 00:26:27,680 --> 00:26:32,680 Individual lines in three, two, one, go. 502 00:26:33,680 --> 00:26:39,680 This first test, the standard choose your lane method will last exactly 30 minutes. 503 00:26:39,680 --> 00:26:42,680 That looks pretty much like a busy normal store. 504 00:26:42,680 --> 00:26:49,680 And to make their data as reliable as possible, the MythBusters are cranking the realism up to the max. 505 00:26:49,680 --> 00:26:55,680 Now, some of you who've been watching up to this point might be thinking that we haven't said a totally real world shopping scenario, 506 00:26:55,680 --> 00:26:59,680 because we don't have people who slow the lines down with special requests. 507 00:26:59,680 --> 00:27:01,680 Ye of little faith. 508 00:27:01,680 --> 00:27:04,680 We've actually built two bogies into our testing procedure. 509 00:27:04,680 --> 00:27:06,680 One is a price check. 510 00:27:06,680 --> 00:27:13,680 A certain number of our shoppers will require one, and they'll call us on the radio, and Jamie or I will go out and give the actual price. 511 00:27:13,680 --> 00:27:14,680 There you go. 512 00:27:14,680 --> 00:27:15,680 One happened right there. 513 00:27:15,680 --> 00:27:16,680 Oh, okay. 514 00:27:16,680 --> 00:27:17,680 That's $3.99. 515 00:27:17,680 --> 00:27:21,680 The other one is the most dreaded of shopping scenarios. 516 00:27:21,680 --> 00:27:22,680 Bum, bum, bum. 517 00:27:22,680 --> 00:27:25,680 The person who pays with a bank check. 518 00:27:25,680 --> 00:27:31,680 This combined with the price check ought to make our scenario very, very realistic. 519 00:27:31,680 --> 00:27:35,680 There's no doubt that their super store is super real. 520 00:27:35,680 --> 00:27:40,680 And halfway through, there's already a deluge of data. 521 00:27:40,680 --> 00:27:42,680 Sorry, check on two. 522 00:27:42,680 --> 00:27:44,680 Roger that.
