1 00:00:00,000 --> 00:00:03,000 that or 2 00:00:03,000 --> 00:00:06,000 you 3 00:00:14,000 --> 00:00:16,000 that 4 00:00:22,080 --> 00:00:24,080 Yum 5 00:00:25,080 --> 00:00:28,080 yeah 6 00:00:28,080 --> 00:00:35,080 This guy would be a better way to get through this line. 7 00:00:35,080 --> 00:00:40,640 Look at what we have here. 8 00:00:40,640 --> 00:00:43,080 Zombies in a grocery store? 9 00:00:43,080 --> 00:00:45,380 Lining up in everything. 10 00:00:45,380 --> 00:00:50,380 That gives me an idea. 11 00:00:50,380 --> 00:01:18,460 Okay, Jamie, it's time for a pop quiz. 12 00:01:18,460 --> 00:01:22,940 In all the years we've been making Mythbusters, how many explosions have we caused? 13 00:01:22,940 --> 00:01:25,940 I don't know. 14 00:01:25,940 --> 00:01:27,940 Wow, 900. 15 00:01:27,940 --> 00:01:29,780 Okay, here's another one. 16 00:01:29,780 --> 00:01:35,580 How many cars do you think we've destroyed? 17 00:01:35,580 --> 00:01:36,580 No idea. 18 00:01:36,580 --> 00:01:37,580 Close! 19 00:01:37,580 --> 00:01:38,580 220. 20 00:01:38,580 --> 00:01:41,900 Okay, how many volunteers have we used on Mythbusters? 21 00:01:41,900 --> 00:01:43,060 I know this one. 22 00:01:43,060 --> 00:01:44,060 A lot. 23 00:01:44,060 --> 00:01:45,060 You're darn tootin' it's a lot. 24 00:01:45,060 --> 00:01:49,020 We've used over 3,500 volunteers in the years we've made this show. 25 00:01:49,020 --> 00:01:50,980 We literally couldn't do it without them. 26 00:01:50,980 --> 00:01:55,860 That's why in this final season episode we are paying them homage with two more stories 27 00:01:55,860 --> 00:01:58,060 that require some volunteer help. 28 00:01:58,060 --> 00:01:59,060 Like what? 29 00:01:59,060 --> 00:02:02,260 Well, later we're going to be testing a myth that may prove that we've all been waiting 30 00:02:02,260 --> 00:02:05,420 online at the grocery store wrong. 31 00:02:05,420 --> 00:02:09,820 I felt a little numb on the pride that we just opened our first business and we've 32 00:02:09,820 --> 00:02:11,060 got all these customers. 33 00:02:11,060 --> 00:02:21,060 But first up is a fan favorite that has become a fan favorite to complain about our zombie 34 00:02:21,060 --> 00:02:25,300 episode, specifically Axe vs. Gunn. 35 00:02:25,300 --> 00:02:27,460 I thought we did that in Axe 1. 36 00:02:27,460 --> 00:02:32,140 Well, Axe did win, but fans had to complain about my axe technique. 37 00:02:32,140 --> 00:02:35,140 I think they called it lame. 38 00:02:36,140 --> 00:02:43,380 Yep, in the epic zombie special, Adam's axe killed twice as many zombies as Jamie's 39 00:02:43,380 --> 00:02:47,020 Gunn. 40 00:02:47,020 --> 00:02:51,300 But fans cried foul. 41 00:02:51,300 --> 00:02:57,580 So in this final season, it's now or never for a dawn of the dead do-over. 42 00:02:57,580 --> 00:02:59,140 You remember this axe, don't you? 43 00:02:59,140 --> 00:03:00,700 It's my zombie killing axe. 44 00:03:00,700 --> 00:03:05,460 And while I used it to kill zombies in our zombie episode, fans had problems with the 45 00:03:05,460 --> 00:03:06,780 way I was doing it. 46 00:03:06,780 --> 00:03:10,980 I was touching them and saying they're dead. 47 00:03:10,980 --> 00:03:15,940 Fans pointed out rightly, I might add, that it takes a certain amount of force to embed 48 00:03:15,940 --> 00:03:18,060 an axe in a zombie's head. 49 00:03:18,060 --> 00:03:22,860 And that's something that we're going to try and replicate to make this more realistic. 50 00:03:22,860 --> 00:03:27,900 And to do just that, Adam's starting this volunteer special by breaking the mold. 51 00:03:27,900 --> 00:03:30,140 Oh, check it out! 52 00:03:30,140 --> 00:03:34,580 Dude, are you ready to have your forehead split with an axe? 53 00:03:34,580 --> 00:03:35,980 It's too late. 54 00:03:35,980 --> 00:03:37,900 That's what you were born to do. 55 00:03:37,900 --> 00:03:39,900 Let's go. 56 00:03:39,900 --> 00:03:45,100 Adam's anatomically accurate fake head will help his axe wing be more real. 57 00:03:45,100 --> 00:03:46,100 But how? 58 00:03:46,100 --> 00:03:47,100 This is Jeremy. 59 00:03:47,100 --> 00:03:50,140 He's a friend of mine who has helped me on some projects in the past. 60 00:03:50,140 --> 00:03:53,740 Today he's brought some electronics to help us calibrate our axe hits. 61 00:03:53,740 --> 00:03:54,740 What do we have here, sir? 62 00:03:54,860 --> 00:03:58,140 Well, we have an accelerometer here tied into a microcontroller. 63 00:03:58,140 --> 00:04:02,180 And the accelerometer reads acceleration and deceleration on three axes. 64 00:04:02,180 --> 00:04:07,620 So what I'm hoping to do, if this works, is attach this to the back of our real axe head, 65 00:04:07,620 --> 00:04:11,740 cleave our fake zombie in half, and get a value of how much force that takes. 66 00:04:11,740 --> 00:04:12,740 Yes. 67 00:04:12,740 --> 00:04:13,740 And that's what we'll get with this machine? 68 00:04:13,740 --> 00:04:14,740 Yes, we will. 69 00:04:14,740 --> 00:04:15,740 Awesome. 70 00:04:15,740 --> 00:04:16,740 Let's do it. 71 00:04:16,740 --> 00:04:21,580 With the accelerometer taped into place, it's time to swing for science. 72 00:04:21,580 --> 00:04:23,100 Zombie killing. 73 00:04:23,100 --> 00:04:27,100 This is more gruesome than I thought it would be when we talked about this in the abstract. 74 00:04:31,100 --> 00:04:32,700 That was terrible. 75 00:04:32,700 --> 00:04:34,500 I grazed the side of his skull. 76 00:04:34,500 --> 00:04:37,500 Yep, take one was not a zombie kill. 77 00:04:37,500 --> 00:04:38,500 Look at that. 78 00:04:38,500 --> 00:04:40,620 I peeled off a bit of his flesh. 79 00:04:40,620 --> 00:04:47,500 Take two has accuracy, but lacks the power to penetrate to the brain. 80 00:04:47,500 --> 00:04:48,700 That was not a kill. 81 00:04:48,700 --> 00:04:50,220 You got to hit him harder. 82 00:04:50,340 --> 00:04:51,340 Take three. 83 00:04:51,340 --> 00:04:57,940 Yeah, dead zombies all day long. 84 00:04:57,940 --> 00:05:00,220 Get the kill data Adam needs. 85 00:05:00,220 --> 00:05:03,140 All right, so I successfully killed my zombie head. 86 00:05:03,140 --> 00:05:08,900 And to do so, I swung this axe on a 120 degree arc at 7.8 meters per second. 87 00:05:08,900 --> 00:05:11,980 Now comes the cool part. 88 00:05:11,980 --> 00:05:16,180 We're going to put the same accelerometer onto my original foam axe, along with a special 89 00:05:16,180 --> 00:05:18,020 control unit that Jeremy's been building. 90 00:05:18,020 --> 00:05:19,660 So where do you want that? 91 00:05:19,660 --> 00:05:21,180 Right up here, right up top. 92 00:05:21,180 --> 00:05:26,420 Now when I swing that foam axe through 120 degrees at any speed that is 7.8 meters per 93 00:05:26,420 --> 00:05:31,540 second or higher, then the control unit will let me know I've successfully registered a 94 00:05:31,540 --> 00:05:32,540 kill. 95 00:05:32,540 --> 00:05:33,940 We just made this the coolest toy ever. 96 00:05:33,940 --> 00:05:37,980 But if my swing is not long enough, fast enough or hard enough, it's going to tell me I've 97 00:05:37,980 --> 00:05:39,740 got to swing again. 98 00:05:39,740 --> 00:05:45,020 And to let Adam know his swing success, the unit's been rigged with two sensory systems. 99 00:05:45,020 --> 00:05:47,100 Okay, the machine's ready. 100 00:05:47,100 --> 00:05:48,100 Yeah. 101 00:05:48,100 --> 00:05:49,100 Did you see that? 102 00:05:49,100 --> 00:05:50,100 It says kill? 103 00:05:50,100 --> 00:05:51,100 That's brilliant. 104 00:05:51,100 --> 00:05:52,100 Ooh, that's not enough. 105 00:05:52,100 --> 00:05:53,100 That's not enough. 106 00:05:53,100 --> 00:05:54,100 That's not enough. 107 00:05:54,100 --> 00:05:55,100 That's enough. 108 00:05:55,100 --> 00:06:06,100 Okay, killing zombies, I can tell right now, is going to be tiring. 109 00:06:06,100 --> 00:06:09,460 I'm going to do some push-ups. 110 00:06:09,460 --> 00:06:11,740 Adam's rig is really pretty nifty. 111 00:06:11,740 --> 00:06:15,660 Like last time, it's got a foam head, so it's safe to actually swing near people. 112 00:06:15,660 --> 00:06:17,980 This foam just soaks up the bang. 113 00:06:17,980 --> 00:06:21,900 And now it not only weighs the same as a real axe, but it also takes a realistic amount 114 00:06:21,900 --> 00:06:23,400 of effort to swing. 115 00:06:23,400 --> 00:06:25,660 Oh my God. 116 00:06:25,660 --> 00:06:30,980 So me and my gun may yet come out trumps. 117 00:06:30,980 --> 00:06:38,060 But before the zombie volunteers arrive, the guys must first start their store story. 118 00:06:38,060 --> 00:06:42,940 All right, our next volunteer story is one I have literally always wanted to test, and 119 00:06:42,940 --> 00:06:45,460 it involves waiting online at the grocery store. 120 00:06:45,460 --> 00:06:46,460 What's that? 121 00:06:46,460 --> 00:06:47,460 All right. 122 00:06:47,460 --> 00:06:50,980 So you get your items, and then you're confronted with a whole bunch of checkout lanes, and you 123 00:06:50,980 --> 00:06:56,140 try and assess which one is moving faster so you can get out of that grocery store efficiently. 124 00:06:56,140 --> 00:06:57,140 Yeah. 125 00:06:57,140 --> 00:07:00,980 Well, there's a theory out there that that whole system is totally inefficient, that 126 00:07:00,980 --> 00:07:05,780 the best way to move people through a grocery store is to have one long, snaking line that 127 00:07:05,780 --> 00:07:09,060 when you get to the end of it, you're led to the next available cashier. 128 00:07:09,060 --> 00:07:10,980 And that's supposed to be faster. 129 00:07:10,980 --> 00:07:11,980 It is. 130 00:07:11,980 --> 00:07:13,260 Don't you think we should test that? 131 00:07:13,260 --> 00:07:14,260 Sure. 132 00:07:14,260 --> 00:07:15,260 Why not? 133 00:07:16,020 --> 00:07:22,100 Since the 1960s, the average American has spent 80 hours a year standing in line. 134 00:07:22,100 --> 00:07:25,500 But is it true we've been waiting wrong for so long? 135 00:07:29,500 --> 00:07:35,340 Well, in this final season, it's time to answer this classic conundrum once and for all. 136 00:07:35,340 --> 00:07:37,660 To test this myth, we're going to need a market. 137 00:07:37,660 --> 00:07:40,540 Unfortunately, nobody would let us use theirs. 138 00:07:40,540 --> 00:07:41,540 Not surprising. 139 00:07:41,540 --> 00:07:43,860 I mean, if I had one, I wouldn't let us use it either. 140 00:07:46,260 --> 00:07:51,300 This is why we can't have nice things. 141 00:07:51,300 --> 00:07:53,140 So we're going to make our own. 142 00:07:53,140 --> 00:07:54,140 That's right. 143 00:07:54,140 --> 00:07:57,500 In a few short hours, we are going to use little elbow grease to turn this beautiful empty 144 00:07:57,500 --> 00:08:03,140 room into a running grocery store full of aisles, products, check-out stands, and ultimately 145 00:08:03,140 --> 00:08:04,140 customers. 146 00:08:04,140 --> 00:08:07,420 Welcome to MythBus Store. 147 00:08:07,420 --> 00:08:11,860 With no real stores willing to play ball, I'll do the aisles if you do the registers. 148 00:08:11,860 --> 00:08:12,860 Absolutely. 149 00:08:12,860 --> 00:08:13,860 Here you go. 150 00:08:13,860 --> 00:08:15,620 MythBusters are going to have to build their own. 151 00:08:15,620 --> 00:08:18,580 Oh, it doesn't look like much, but it's going to be awesome. 152 00:08:18,580 --> 00:08:23,140 Adam's starting at the business end by assembling their homemade cash registers. 153 00:08:23,140 --> 00:08:24,780 Next one. 154 00:08:24,780 --> 00:08:26,940 He's fabricating five in total. 155 00:08:26,940 --> 00:08:27,940 Lovely. 156 00:08:27,940 --> 00:08:31,060 And they'll form the key part of their MythBusters mini-mart. 157 00:08:31,060 --> 00:08:33,140 Oh, yeah, cash registers. 158 00:08:33,140 --> 00:08:34,140 It's real. 159 00:08:34,140 --> 00:08:35,140 And that's not all. 160 00:08:35,140 --> 00:08:36,140 The coolest part. 161 00:08:36,140 --> 00:08:42,220 Lit up signs that tell the customers which is the next free aisle. 162 00:08:42,340 --> 00:08:44,340 Meanwhile, Jamie's on the shelf. 163 00:08:44,340 --> 00:08:47,060 This is going to take a while. 164 00:08:47,060 --> 00:08:55,700 With almost 800 feet of shelving for the guys to stack and pack, it's up back-breaking business. 165 00:08:55,700 --> 00:08:58,380 But it does have its advantages. 166 00:08:58,380 --> 00:09:02,780 It might seem tedious to have to build our own store, but it allows us to remove variables 167 00:09:02,780 --> 00:09:06,940 that we might find in a real store that would be beyond our control. 168 00:09:06,940 --> 00:09:07,940 Jamie's right. 169 00:09:08,060 --> 00:09:13,220 A real supermarket will already have a layout locked in and won't want anything to slow 170 00:09:13,220 --> 00:09:15,340 down sales. 171 00:09:15,340 --> 00:09:19,980 So MythBus stores is the way to go. 172 00:09:19,980 --> 00:09:22,100 But a build as big as this... 173 00:09:22,100 --> 00:09:24,180 I have always wanted to do this. 174 00:09:24,180 --> 00:09:29,460 ...is something the guys can only pull off because of their experience. 175 00:09:29,460 --> 00:09:30,460 We thought of everything. 176 00:09:30,460 --> 00:09:32,820 We've got baskets too. 177 00:09:32,820 --> 00:09:36,020 This is exactly the kind of episode we never would have attempted in the early days of 178 00:09:36,020 --> 00:09:37,020 MythBusters. 179 00:09:37,020 --> 00:09:41,380 We didn't have the ambition nor the skill to work with large groups of volunteers and 180 00:09:41,380 --> 00:09:44,100 to build our own large-scale experimental spaces. 181 00:09:44,100 --> 00:09:47,100 But we have learned so much over the years. 182 00:09:47,100 --> 00:09:51,300 This is the pinnacle of our ability to work in a budget on a timeline with a whole bunch 183 00:09:51,300 --> 00:09:53,420 of volunteers to test something. 184 00:09:53,420 --> 00:09:56,940 It's certainly ambitious. 185 00:09:56,940 --> 00:09:59,660 And with 5,000 products to place... 186 00:09:59,660 --> 00:10:01,060 Time to start stacking. 187 00:10:01,060 --> 00:10:06,300 It's the perfect go-big or go-home setup for this fanfare well. 188 00:10:06,300 --> 00:10:12,940 What we are 10 hours in and our check-out stands are complete and ready and wired. 189 00:10:12,940 --> 00:10:14,420 Our shelves are up. 190 00:10:14,420 --> 00:10:17,660 But now it's time to stock and there's a lot to stock. 191 00:10:17,660 --> 00:10:19,660 Eat corn! 192 00:10:19,660 --> 00:10:22,500 We are about halfway there with still a fair bit to go. 193 00:10:22,500 --> 00:10:24,580 Alright, ready on aisle 3. 194 00:10:24,580 --> 00:10:29,020 Oh, we don't have any customers yet. 195 00:10:29,020 --> 00:10:35,420 Still to come in this epic volunteer special, it's the dawn of the dead in Acts vs. Gun. 196 00:10:35,420 --> 00:10:41,260 But next, Adam and Jamie shop till they drop. 197 00:10:41,260 --> 00:10:42,260 MythBustor! 198 00:10:42,260 --> 00:10:45,420 Where shopping is fully experimental. 199 00:10:45,420 --> 00:10:55,540 Our other tagline was, we're making this up as we go along. 200 00:10:55,540 --> 00:11:01,180 From testing the laws of attraction to comparing hand hygiene. 201 00:11:01,180 --> 00:11:04,660 Our test subject group seems to have developed its own ritual. 202 00:11:04,660 --> 00:11:10,820 The MythBusters have spent 14 years sourcing volunteers for stories big and small. 203 00:11:10,820 --> 00:11:16,380 She doesn't want to let go. 204 00:11:16,380 --> 00:11:26,180 And in this farewell season, Adam and Jamie have crowdsourced two final crowds. 205 00:11:26,180 --> 00:11:35,980 Starting with the undead. 206 00:11:35,980 --> 00:11:38,860 Here we are back at the scene of our original experiment. 207 00:11:38,860 --> 00:11:41,380 Our zombie battle dome, if you will. 208 00:11:41,380 --> 00:11:45,900 We've got the same exact experimental setup with some new colors and the same weapons. 209 00:11:45,900 --> 00:11:47,860 Jamie gets a gun, I get an axe. 210 00:11:47,860 --> 00:11:49,860 All we need are zombies. 211 00:11:49,860 --> 00:11:54,580 Oh, crap. 212 00:11:54,580 --> 00:12:00,780 With almost 200 volunteer zombies back from the dead, the guys have everything they need 213 00:12:00,780 --> 00:12:06,540 to retest the myth that fans complained about more than any other. 214 00:12:06,540 --> 00:12:10,460 Their biggest complaint was with my axe, specifically my technique. 215 00:12:10,460 --> 00:12:12,820 They said that it was too lightweight. 216 00:12:12,820 --> 00:12:16,580 They suggested, the fans did, that every time I swing the axe it should be with enough 217 00:12:16,580 --> 00:12:21,820 force to actually kill a zombie. 218 00:12:21,820 --> 00:12:27,380 With the axe able to tell if Adam's using enough force to kill, let's go. 219 00:12:27,380 --> 00:12:28,380 Watch the plan. 220 00:12:28,380 --> 00:12:29,580 So how's this going to work? 221 00:12:29,580 --> 00:12:35,700 Well, when I start the timer and I do this, that lets the zombies know that it's time 222 00:12:35,700 --> 00:12:38,100 to get down to business. 223 00:12:38,100 --> 00:12:42,220 And then when I see that the zombies have overtaken Adam, I use this again. 224 00:12:42,220 --> 00:12:43,340 I stop them. 225 00:12:43,340 --> 00:12:47,740 We do a zombie body count and we see how Adam did with his new axe. 226 00:12:47,740 --> 00:12:51,620 It's time for zombies. 227 00:12:51,620 --> 00:12:58,140 In the original episode, Adam dispatched 14 zombies before getting bit. 228 00:12:58,140 --> 00:13:03,100 But how will his new accurate axe work out? 229 00:13:03,100 --> 00:13:07,180 What a fine looking group of ladies and gentlemen we all are. 230 00:13:07,180 --> 00:13:09,180 Are you hungry? 231 00:13:09,180 --> 00:13:12,980 Okay, here we go. 232 00:13:12,980 --> 00:13:18,300 In three, two, one. 233 00:13:18,300 --> 00:13:24,940 This is go time and as soon as the zombies enter the circle, Adam's off and swinging 234 00:13:24,940 --> 00:13:30,740 hard. 235 00:13:30,740 --> 00:13:36,740 But not for long. 236 00:13:36,740 --> 00:13:44,980 With just eight confirmed kills, barely half that of last time, Adam's total has tanked. 237 00:13:44,980 --> 00:13:48,460 This technique seemed to be to run around the perimeter of the circle as fast as he 238 00:13:48,460 --> 00:13:51,700 could to collect as many zombie bodies as he could. 239 00:13:51,700 --> 00:13:57,900 But he's having to put a lot of effort into getting it going and it actually takes a lot 240 00:13:57,900 --> 00:13:58,900 more time. 241 00:13:58,900 --> 00:14:05,300 From above, it looked like an iris that was closing on Adam and when it got small enough, 242 00:14:05,300 --> 00:14:07,300 he was done for. 243 00:14:07,300 --> 00:14:11,180 The new technique has clearly slowed Adam down. 244 00:14:11,180 --> 00:14:16,060 But the key question remains, how does the axe compare to the gun? 245 00:14:16,060 --> 00:14:17,060 It's time. 246 00:14:17,060 --> 00:14:22,380 Okay, zombies, face masks down. 247 00:14:22,380 --> 00:14:27,500 To find out Jamie's armed with a paintball pistol that, at the request of fans, has been 248 00:14:27,500 --> 00:14:30,500 set to semi-automatic. 249 00:14:30,500 --> 00:14:33,860 Alright zombies, are you ready? 250 00:14:33,860 --> 00:14:39,220 Are you ready for some sweet, sweet Heidemann flush brains? 251 00:14:39,220 --> 00:14:40,780 Alright, here we go. 252 00:14:40,780 --> 00:14:52,060 Starting gun test in three, two, one. 253 00:14:52,060 --> 00:14:57,140 From the get go, it's clear that Jamie's semi-auto is fast. 254 00:14:57,140 --> 00:15:07,540 But it's not fast enough to let him shoot his way out of trouble. 255 00:15:07,540 --> 00:15:13,140 In total, Jamie manages only seven kills, one less than Adam. 256 00:15:13,140 --> 00:15:15,780 One of my favorite things about this show, one of the most scientific things that we 257 00:15:15,780 --> 00:15:21,060 do is we take feedback after episodes have aired and we go back and re-retest things. 258 00:15:21,060 --> 00:15:22,380 I love that. 259 00:15:22,380 --> 00:15:27,180 Fans did not like my axe technique, so we rejiggered it, made my axe much more realistic 260 00:15:27,180 --> 00:15:31,380 to swing and as expected, that radically reduced the number of zombies that I could 261 00:15:31,380 --> 00:15:32,380 kill. 262 00:15:33,220 --> 00:15:36,780 But I thought that Jamie was going to mop the floor with me with his use of his new 263 00:15:36,780 --> 00:15:43,580 semi-auto paintball pistol and yet he didn't improve his score at all. 264 00:15:43,580 --> 00:15:51,180 I am totally gobsmacked that it seems right now like axe versus gun, it's axe. 265 00:15:51,180 --> 00:15:55,180 Oh yeah. 266 00:15:56,140 --> 00:16:02,180 Yep, despite the slowdown, the axe is ahead by a head. 267 00:16:02,180 --> 00:16:05,300 But there's way more to come for our armchair army. 268 00:16:05,300 --> 00:16:07,300 I'm ready. 269 00:16:10,620 --> 00:16:13,940 But only after some retail therapy. 270 00:16:13,940 --> 00:16:16,460 And we are pretty much done. 271 00:16:16,460 --> 00:16:20,780 Five checkout stands each with working cash registers and indicator lights. 272 00:16:20,780 --> 00:16:25,980 Five thousand separate food items are rated on over 750 feet of shelving, every single 273 00:16:25,980 --> 00:16:28,140 one with its own label. 274 00:16:28,140 --> 00:16:31,740 $56,000 in play, myth busters, money. 275 00:16:31,740 --> 00:16:36,380 This is without a doubt the most elaborate experimental setup we have ever implemented, 276 00:16:36,380 --> 00:16:39,740 all to find out which is the more efficient way to wait online. 277 00:16:39,740 --> 00:16:43,140 Now we are pretty much ready to go, we just got to make sure that everything is properly 278 00:16:43,140 --> 00:16:44,140 priced. 279 00:16:44,140 --> 00:16:46,540 This one doesn't have a price, that's a problem. 280 00:16:46,540 --> 00:16:51,300 The guys are testing whether the traditional picolain method is really slower than one 281 00:16:51,300 --> 00:16:57,500 long line, known in the trade as the serpentine. 282 00:16:57,500 --> 00:17:05,740 And with their 5000 products all priced, their elaborate plan is ready to be revealed. 283 00:17:05,740 --> 00:17:07,220 Here's how this experimental setup works. 284 00:17:07,220 --> 00:17:11,340 We've got 120 volunteers and they will enter the store where they'll receive a shopping 285 00:17:11,340 --> 00:17:16,460 list of exactly how many items we want them to buy, then they'll go get a cart. 286 00:17:16,460 --> 00:17:19,660 Once they have their cart they'll enter the store and choose from the vast selection of 287 00:17:19,660 --> 00:17:21,460 myth busters merchandise on display. 288 00:17:21,460 --> 00:17:24,420 Personally, I hope we get cookies. 289 00:17:24,420 --> 00:17:28,780 Once our customer gets in line for the cashier, that's when the data collection actually begins. 290 00:17:28,780 --> 00:17:33,820 They will pull out their timestamp card and enter the precise moment they got in line. 291 00:17:33,820 --> 00:17:36,720 Then they'll proceed right towards the cashier. 292 00:17:36,720 --> 00:17:40,740 Once our customer reaches the cashier, that's when they enter the second data point, the 293 00:17:40,740 --> 00:17:42,980 time they got to the checkout stand. 294 00:17:42,980 --> 00:17:48,580 Thus we will have the precise length of time they spend waiting in line. 295 00:17:48,580 --> 00:17:53,140 Our last stop is here, data collection, where we not only gather our customers' timestamp, 296 00:17:53,140 --> 00:17:55,620 but we're also interested in their experience. 297 00:17:55,620 --> 00:17:59,740 So in the back of each time card they will grade their overall satisfaction with the 298 00:17:59,740 --> 00:18:02,980 line. 299 00:18:02,980 --> 00:18:10,860 With five experienced register operators and a stats table staffed by experts, everything 300 00:18:10,860 --> 00:18:15,860 set to release the volunteers for first a full systems check. 301 00:18:15,860 --> 00:18:25,740 Alright shoppers, starting in three, two, one, go for the run through. 302 00:18:25,740 --> 00:18:30,820 I felt a little moment of pride that we just opened our first business and we've got all 303 00:18:30,820 --> 00:18:34,220 these customers. 304 00:18:34,220 --> 00:18:39,100 The guys are starting with a trial run to make sure their newly built store can cope, 305 00:18:39,100 --> 00:18:45,220 which at first it can. 306 00:18:45,220 --> 00:18:49,900 But ten minutes later, the lines have become unrealistically long. 307 00:18:49,900 --> 00:18:55,140 We're already seeing some problems with our experimental design because our entire customer 308 00:18:55,140 --> 00:19:00,940 base ended up in long lines and that's not realistically like what we would have in a 309 00:19:00,940 --> 00:19:05,420 store so we're going to have to figure out some way of pacing things a little bit to 310 00:19:05,420 --> 00:19:11,300 get lines that are more realistically sized to what you would see in a supermarket. 311 00:19:11,300 --> 00:19:17,140 Yep with just too many shoppers, all at once, their commercial space can't cope. 312 00:19:17,140 --> 00:19:21,060 So the guys kick out their customers and reset. 313 00:19:21,060 --> 00:19:25,700 Alright shoppers, commence entering the store. 314 00:19:25,700 --> 00:19:28,860 This time with 25% fewer people. 315 00:19:28,860 --> 00:19:32,580 There's a special on Jamie Beans on aisle four. 316 00:19:32,580 --> 00:19:36,740 Which soon results in queues that are much more realistic. 317 00:19:36,740 --> 00:19:38,980 Jamie this is working beautifully. 318 00:19:38,980 --> 00:19:41,980 Meaning that the testing can shortly begin. 319 00:19:41,980 --> 00:19:46,500 We have done countless destructive stories over the years, but I also love myths like 320 00:19:46,500 --> 00:19:47,500 this one. 321 00:19:47,500 --> 00:19:50,540 I mean I think when we do something like this we might make the world a slightly better place 322 00:19:50,540 --> 00:19:53,260 by improving people's shopping experience. 323 00:19:53,260 --> 00:19:54,260 That's cool. 324 00:19:54,260 --> 00:19:59,420 That doesn't mean there can't be any destruction like this. 325 00:19:59,420 --> 00:20:09,980 Clean up on aisle five. 326 00:20:09,980 --> 00:20:12,980 The mythbusters have helped drivers save dollars. 327 00:20:12,980 --> 00:20:17,780 The dimpled car, 29.65 miles to the gallon. 328 00:20:17,780 --> 00:20:20,180 And revealed ways to save lives. 329 00:20:20,180 --> 00:20:21,980 It's going down. 330 00:20:21,980 --> 00:20:23,500 Oh boy. 331 00:20:23,500 --> 00:20:27,940 In fact they've always armed viewers with important information. 332 00:20:27,940 --> 00:20:33,580 Did you know what was lurking in your basement? 333 00:20:33,580 --> 00:20:40,500 But at an apocalyptic warehouse let's hope this myth's strange stats aren't ever needed. 334 00:20:40,500 --> 00:20:41,780 So where do we stand? 335 00:20:41,780 --> 00:20:48,020 Well so far it still looks like Axe is edging out gun as a method for dispatching zombies. 336 00:20:48,020 --> 00:20:51,940 However our testing scenario where zombies are coming from all sides. 337 00:20:51,940 --> 00:20:57,380 That is genuinely like the worst possible case scenario under which you could encounter 338 00:20:57,380 --> 00:20:58,380 zombies. 339 00:20:58,380 --> 00:21:02,060 In movies it's much more likely that they're like trying to get in and they get through 340 00:21:02,060 --> 00:21:05,940 something like a breach or a doorway. 341 00:21:05,940 --> 00:21:09,180 So that is the scenario we're going to set up next. 342 00:21:09,180 --> 00:21:14,900 It may sound like an oxymoron but the guys are trying to up the realism of their zombie 343 00:21:14,900 --> 00:21:15,900 methodology. 344 00:21:15,900 --> 00:21:16,900 Nice. 345 00:21:16,900 --> 00:21:22,700 To do that they're ditching the circle surround test and going instead with the classic fence 346 00:21:22,700 --> 00:21:25,180 breach. 347 00:21:25,180 --> 00:21:45,300 The question is will the axe still be the winning weapon? 348 00:21:45,300 --> 00:21:50,500 Like film folklore the undead start by coming through one by one. 349 00:21:50,500 --> 00:21:52,140 This is working great. 350 00:21:52,140 --> 00:21:58,900 But what Adam doesn't know is that Jamie's about to release the zombies en masse. 351 00:21:58,900 --> 00:22:00,900 Reaching the fence. 352 00:22:00,900 --> 00:22:02,900 Oh no. 353 00:22:02,900 --> 00:22:05,900 With walkers now pouring forward. 354 00:22:05,900 --> 00:22:08,740 A living wall. 355 00:22:08,740 --> 00:22:20,100 Adam's swing frequency has to rapidly rise which causes him to get fatigued fast. 356 00:22:20,100 --> 00:22:27,500 So much so that the power of his swing starts to fall below the kill threshold. 357 00:22:27,500 --> 00:22:33,220 Adam is about exhausted and he's slowly losing the battle. 358 00:22:33,220 --> 00:22:37,540 This is exhausting. 359 00:22:37,540 --> 00:22:41,100 I'm dead. 360 00:22:41,100 --> 00:22:45,100 I'm dead. 361 00:22:45,100 --> 00:22:53,020 That was the hardest thing I've done in a long time. 362 00:22:53,020 --> 00:22:55,420 Looks like that was quite the workout. 363 00:22:55,420 --> 00:22:58,940 While Adam recovers I might have pulled a muscle. 364 00:22:58,940 --> 00:23:01,100 Jamie counts up the dead. 365 00:23:01,100 --> 00:23:03,540 21, 22, 23, 24. 366 00:23:03,540 --> 00:23:06,820 To reveal a final tally that's terrifying. 367 00:23:06,820 --> 00:23:08,900 66, 67. 368 00:23:08,900 --> 00:23:13,500 It could be another body or so buried under there but I'll call it 67. 369 00:23:13,500 --> 00:23:20,620 67's on me. 370 00:23:20,620 --> 00:23:29,620 With 67 the benchmark to beat it's time for Jamie to come out all guns blazing. 371 00:23:29,620 --> 00:23:32,140 I'm ready. 372 00:23:32,140 --> 00:23:34,620 Arm to the teeth and then some. 373 00:23:34,620 --> 00:23:36,980 You want a piece of me? 374 00:23:36,980 --> 00:23:41,340 What the carnage commits. 375 00:23:41,340 --> 00:23:46,020 Please remember zombies that Jamie's flesh comes from Indiana which means it's especially 376 00:23:46,020 --> 00:23:47,020 tasty. 377 00:23:47,020 --> 00:23:51,020 All right, here we go. 378 00:23:51,020 --> 00:23:56,220 In three, two, one. 379 00:23:56,220 --> 00:23:58,980 From the get go. 380 00:23:58,980 --> 00:24:00,540 He's not even moving. 381 00:24:00,540 --> 00:24:03,780 Jamie has a clear advantage over Adam. 382 00:24:03,780 --> 00:24:08,580 As he takes down zombies on both sides of the fence. 383 00:24:08,580 --> 00:24:18,340 But when the fence gets breached, Jamie must really start firing on all summoners. 384 00:24:18,340 --> 00:24:21,020 Excellent. 385 00:24:21,020 --> 00:24:24,700 He's doing good. 386 00:24:24,700 --> 00:24:29,620 Come on Jamie, you can do it. 387 00:24:29,620 --> 00:24:33,660 Jamie may not be tiring but the odd gun jam is slowing him down. 388 00:24:33,660 --> 00:24:36,180 He's going to run around the whole other side of me. 389 00:24:36,180 --> 00:24:37,540 This is kind of great. 390 00:24:37,540 --> 00:24:41,380 So much so that his days in the land of the living are numbered. 391 00:24:41,380 --> 00:24:43,380 He might be dead. 392 00:24:43,380 --> 00:24:50,380 Calm down. 393 00:24:50,380 --> 00:24:54,620 Jamie's dead and buried but did he shoot more than 67? 394 00:24:54,620 --> 00:24:55,620 Mr. Heidemann. 395 00:24:55,620 --> 00:24:56,620 Yes. 396 00:24:56,620 --> 00:24:57,620 Stand up. 397 00:24:58,620 --> 00:25:02,380 You took 57 zombies with you. 398 00:25:02,380 --> 00:25:04,980 Well, I guess Axe beats gun, huh? 399 00:25:04,980 --> 00:25:05,980 That is fascinating. 400 00:25:05,980 --> 00:25:06,980 I would not have called that. 401 00:25:06,980 --> 00:25:08,980 All right, let's clean up this mess. 402 00:25:08,980 --> 00:25:12,980 All I got to say, I was surprised. 403 00:25:12,980 --> 00:25:15,700 You would think that this would be like shooting fish in a barrel. 404 00:25:15,700 --> 00:25:19,580 But these guns are more complex than something like an axe. 405 00:25:19,580 --> 00:25:20,900 They have to be reloaded. 406 00:25:20,900 --> 00:25:22,400 They can jam. 407 00:25:22,400 --> 00:25:26,220 And a second or two is enough to make everything go haywire. 408 00:25:26,220 --> 00:25:28,980 So I ended up scoring less than Adam. 409 00:25:28,980 --> 00:25:31,660 But I was expecting exactly the opposite. 410 00:25:31,660 --> 00:25:35,140 Yep, it's a result to confound the critics. 411 00:25:35,140 --> 00:25:40,780 When the apocalypse comes, folks, Axe does beat gun and then some. 412 00:25:40,780 --> 00:25:47,380 After beating Jamie twice, both in the round and in the breach test, I'm like, damn, Axe, 413 00:25:47,380 --> 00:25:49,740 you are the proper tool. 414 00:25:49,740 --> 00:25:56,180 Not only good for a quest through Middle Earth, but also good against zombies. 415 00:25:56,180 --> 00:26:02,900 But before disbanding their undead army, there's one more zombie request to test. 416 00:26:02,900 --> 00:26:07,020 Carove me. 417 00:26:07,020 --> 00:26:12,740 Meanwhile, back at MythBus stores. 418 00:26:12,740 --> 00:26:15,780 Our employee of the month is James Franklin Heinemann. 419 00:26:15,780 --> 00:26:18,580 He hails from Columbus, Indiana. 420 00:26:18,580 --> 00:26:24,260 The lineup trial run has been such a success that the data collection can now begin. 421 00:26:25,020 --> 00:26:26,860 All right, timer ready. 422 00:26:26,860 --> 00:26:27,860 Here we go. 423 00:26:27,860 --> 00:26:30,100 Commence shopping test. 424 00:26:30,100 --> 00:26:35,540 Individual lines in three, two, one, go. 425 00:26:35,540 --> 00:26:41,220 This first test, the standard choose your lane method will last exactly 30 minutes. 426 00:26:41,220 --> 00:26:44,620 It looks pretty much like a busy normal store. 427 00:26:44,620 --> 00:26:49,940 And to make their data as reliable as possible, the MythBusters are cranking the realism up 428 00:26:49,940 --> 00:26:51,780 to the max. 429 00:26:51,780 --> 00:26:54,900 Now some of you who've been watching up to this point might be thinking that we haven't 430 00:26:54,900 --> 00:26:58,820 set a totally real world shopping scenario because we don't have people who slow the 431 00:26:58,820 --> 00:27:01,300 lines down with special requests. 432 00:27:01,300 --> 00:27:03,500 Yee of little faith. 433 00:27:03,500 --> 00:27:06,700 We've actually built two bogies into our testing procedure. 434 00:27:06,700 --> 00:27:07,980 One is a price check. 435 00:27:07,980 --> 00:27:12,220 A certain number of our shoppers will require one and they'll call us on the radio and Jamie 436 00:27:12,220 --> 00:27:15,540 or I will go out and give the actual price. 437 00:27:15,540 --> 00:27:16,540 There you go. 438 00:27:16,540 --> 00:27:17,540 One happened right there. 439 00:27:17,540 --> 00:27:18,540 Oh, OK. 440 00:27:18,540 --> 00:27:19,540 That's $3.99. 441 00:27:19,660 --> 00:27:22,980 The other one is the most dreaded of shopping scenarios. 442 00:27:22,980 --> 00:27:24,260 Bum, bum, bum. 443 00:27:24,260 --> 00:27:27,780 The person who pays with a bank check. 444 00:27:27,780 --> 00:27:33,460 This combined with the price check ought to make our scenario very, very realistic. 445 00:27:33,460 --> 00:27:38,420 There's no doubt that their super store is super real. 446 00:27:38,420 --> 00:27:42,020 And halfway through, there's already a deluge of data. 447 00:27:42,020 --> 00:27:44,020 OK, check on two. 448 00:27:44,020 --> 00:27:45,020 Roger that. 449 00:27:45,020 --> 00:27:46,660 Mr. Heiden, the price check on two. 450 00:27:46,660 --> 00:27:49,540 Not because Adam's so excited about this store story. 451 00:27:49,540 --> 00:27:51,580 How much is this apple, sir? 452 00:27:51,580 --> 00:27:52,580 $0.99. 453 00:27:52,580 --> 00:27:53,580 Thank you. 454 00:27:53,580 --> 00:27:58,140 He's volunteering to not just observe but to participate too. 455 00:27:58,140 --> 00:27:59,940 Got my card, got my timestamp. 456 00:27:59,940 --> 00:28:01,740 Now it's time to go shopping. 457 00:28:01,740 --> 00:28:04,380 He's been randomly allocated six items. 458 00:28:04,380 --> 00:28:05,980 Grits, yep. 459 00:28:05,980 --> 00:28:08,660 Which he selects based on taste. 460 00:28:08,660 --> 00:28:10,660 Lab grade gravy. 461 00:28:10,660 --> 00:28:11,660 Delicious. 462 00:28:11,660 --> 00:28:14,220 And packaging. 463 00:28:14,220 --> 00:28:19,660 I only buy these because the label features the handsomeest man I've ever seen. 464 00:28:19,660 --> 00:28:24,220 Then like all the other shoppers, he chooses a queue and notes down the time. 465 00:28:24,220 --> 00:28:25,220 24.36. 466 00:28:25,220 --> 00:28:29,620 24.36. 467 00:28:29,620 --> 00:28:33,820 And that's when the boring part, the waiting, begins. 468 00:28:33,820 --> 00:28:36,220 No magazines to read. 469 00:28:36,220 --> 00:28:38,220 I need to know about what's going on with their Kardashians. 470 00:28:38,220 --> 00:28:42,420 This is the only place in the world I can find that out. 471 00:28:42,420 --> 00:28:47,700 Three minutes, 18 seconds after joining the queue, Adam finally reaches the register. 472 00:28:47,700 --> 00:28:49,180 27.54. 473 00:28:49,180 --> 00:28:50,180 27.54. 474 00:28:50,180 --> 00:28:51,180 Thank you. 475 00:28:51,180 --> 00:28:52,180 All right. 476 00:28:52,180 --> 00:28:54,820 Here, I'm buying that banana peel. 477 00:28:54,820 --> 00:29:00,060 But how will that time compare to his fellow shoppers who continue to collect their data 478 00:29:00,060 --> 00:29:05,300 with destiny until, luckily for them, time's up? 479 00:29:05,300 --> 00:29:10,500 Well after a couple of hiccups, we have completed test number one of our line waiting test. 480 00:29:10,500 --> 00:29:12,340 Thank you very much. 481 00:29:12,340 --> 00:29:14,100 I'm very happy with how it went. 482 00:29:14,100 --> 00:29:18,940 In fact, I even participated as a customer during this one and it felt like a very authentic 483 00:29:18,940 --> 00:29:21,940 shopping experience, which is what we want. 484 00:29:21,940 --> 00:29:24,140 Next up, set up the serpentine. 485 00:29:24,140 --> 00:29:34,220 You want a piece of me? 486 00:29:34,220 --> 00:29:39,540 In the Mythbusters Volunteer Special, the guys have shown that Axe does trump gun. 487 00:29:39,700 --> 00:29:44,540 That was the hardest thing I've done in a long time. 488 00:29:44,540 --> 00:29:50,700 But fans also want to know if its gasoline-powered bigger brother is even better. 489 00:29:50,700 --> 00:29:55,260 And for that, Adam's taking up pit stop at the shop. 490 00:29:55,260 --> 00:29:59,220 While we've been playing around with guns and axes, I have to say I feel we have neglected 491 00:29:59,220 --> 00:30:04,100 perhaps the most spectacular of zombie killing tools and no zombie apocalypse would be complete 492 00:30:04,100 --> 00:30:09,340 without it, the humble chainsaw. 493 00:30:09,340 --> 00:30:16,260 Although the Axe was awesome, viewers want to know if the iconic chainsaw is really a 494 00:30:16,260 --> 00:30:21,740 zombie's ultimate enemy. 495 00:30:21,740 --> 00:30:26,780 To find out, first Adam must calibrate his weapon so that it can reliably register a 496 00:30:26,780 --> 00:30:29,280 kill. 497 00:30:29,280 --> 00:30:32,180 And for that, he's switching things up. 498 00:30:32,180 --> 00:30:39,300 When I take a chainsaw and I touch a zombie, there's a certain length of time I touch him 499 00:30:39,300 --> 00:30:42,060 for before I've cut through his skull and his cranium. 500 00:30:42,060 --> 00:30:44,820 I'm guessing three quarters of a second. 501 00:30:44,820 --> 00:30:49,340 So what I've done is I've set a switch into this chainsaw that will start a timer going 502 00:30:49,340 --> 00:30:52,460 that will go BING every time I've killed a zombie. 503 00:30:52,460 --> 00:30:53,460 And this is the switch. 504 00:30:53,460 --> 00:30:58,660 It's a little bit of a UHMW guide, a micro switch, and when I touch a zombie, it clicks 505 00:30:58,660 --> 00:31:00,860 the switch. 506 00:31:00,860 --> 00:31:02,360 Hear that? 507 00:31:02,360 --> 00:31:07,700 Adam's timer switch will ensure that he can kill zombies unrealistically fast. 508 00:31:07,820 --> 00:31:09,020 Dead zombie. 509 00:31:09,020 --> 00:31:10,020 Dead zombie. 510 00:31:10,020 --> 00:31:11,940 That's how this is going to work. 511 00:31:11,940 --> 00:31:17,180 But so as to not really harm our volunteers, he's also swapping out the blade for something 512 00:31:17,180 --> 00:31:19,460 significantly less sharp. 513 00:31:19,460 --> 00:31:21,820 I've got to kill zombies without hurting them. 514 00:31:21,820 --> 00:31:25,420 Next comes the predictable paint job. 515 00:31:25,420 --> 00:31:32,220 Before one last addition, a blood spatter system to crank the realism to the max. 516 00:31:32,220 --> 00:31:33,500 Everyone knows zombie blood isn't red. 517 00:31:33,500 --> 00:31:35,100 It's a family show. 518 00:31:35,100 --> 00:31:39,660 And with that, it's finally ready for a full systems check. 519 00:31:39,660 --> 00:31:41,980 This is test number one. 520 00:31:41,980 --> 00:31:42,980 Zombie killing chainsaw. 521 00:31:42,980 --> 00:31:55,860 Let's go kill some zombies. 522 00:31:55,860 --> 00:32:01,300 But before we start that mayhem, it's back to the MythBest store shopping spectacular, 523 00:32:01,420 --> 00:32:06,020 Adam and Jamie are tackling a classic queuing conundrum. 524 00:32:06,020 --> 00:32:10,940 Just remember shoppers, there's also a special on Jamie beans in aisle four. 525 00:32:10,940 --> 00:32:17,020 They're trying to find out whether it's quicker to wait in individual lanes or one giant line. 526 00:32:17,020 --> 00:32:19,980 Here's a little something for your trouble. 527 00:32:19,980 --> 00:32:27,020 And with the 30 minute choose your lane test ticked off, the store manager has the stats. 528 00:32:27,020 --> 00:32:30,700 Well test one is done, the results are in, and I have this handy palm full of figures. 529 00:32:31,100 --> 00:32:33,140 The process 138 shoppers. 530 00:32:33,140 --> 00:32:36,620 They averaged a wait time of five minutes and 39 seconds. 531 00:32:36,620 --> 00:32:38,820 The fastest was two minutes 16 seconds. 532 00:32:38,820 --> 00:32:41,300 The slowest nine minutes and 21 seconds. 533 00:32:41,300 --> 00:32:43,140 That was an unhappy shopper. 534 00:32:43,140 --> 00:32:47,380 And they had an average satisfaction level of 3.48 out of five. 535 00:32:47,380 --> 00:32:49,220 I think that's a little bit above average. 536 00:32:49,220 --> 00:32:52,500 Now what does this mean when the serpentine line happens? 537 00:32:52,500 --> 00:32:55,260 I can't see it changing it that much. 538 00:32:55,260 --> 00:32:56,460 I could be wrong. 539 00:32:56,460 --> 00:33:01,500 To find out, the guys set up their serpentine, which is pretty simple. 540 00:33:01,500 --> 00:33:05,540 Basically the serpentine line is just a single line. 541 00:33:05,540 --> 00:33:10,380 It may snake around like a serpent, but that's just to fit in the store more conveniently. 542 00:33:10,380 --> 00:33:12,460 Darn right it's a long line. 543 00:33:12,460 --> 00:33:18,020 The customer at the head of the line simply waits for the next available cashier and he 544 00:33:18,020 --> 00:33:19,740 goes there. 545 00:33:19,740 --> 00:33:23,020 That's the concept, but to see if it's faster. 546 00:33:23,020 --> 00:33:24,020 Cashiers are you ready? 547 00:33:24,020 --> 00:33:25,020 Yeah. 548 00:33:25,020 --> 00:33:30,500 The guys open for business for their 90 volunteers. 549 00:33:30,500 --> 00:33:31,500 Go. 550 00:33:31,500 --> 00:33:34,300 But the test won't start straight away. 551 00:33:34,300 --> 00:33:39,180 You might be wondering at this point why we're letting our store run before starting to gather 552 00:33:39,180 --> 00:33:40,180 any data. 553 00:33:40,180 --> 00:33:43,540 And the reason is, well it's best to think of our store like a marble run. 554 00:33:43,540 --> 00:33:46,020 It looks like I'll choose the other player here. 555 00:33:46,020 --> 00:33:50,420 So if you have a marble run with tracks and wheels and you dump 50 marbles in all at once, 556 00:33:50,420 --> 00:33:54,820 you're going to start in a clump and then slowly disperse throughout the machine as it 557 00:33:54,820 --> 00:33:55,820 goes. 558 00:33:55,820 --> 00:33:57,140 That's exactly what we're doing here. 559 00:33:57,140 --> 00:33:59,780 We're bringing in our people and then letting them disperse. 560 00:33:59,780 --> 00:34:04,260 And once they're dispersed, that's when our data is going to be more accurate because 561 00:34:04,260 --> 00:34:06,540 it's more averaged across the system. 562 00:34:06,540 --> 00:34:12,100 It takes five minutes to achieve an optimum dispersal and then it's all systems go. 563 00:34:12,100 --> 00:34:18,700 All right let's start the clock in three, two, one, commence continuing shopping. 564 00:34:18,700 --> 00:34:22,980 To ensure a valid comparison, they're using the same number of volunteers. 565 00:34:22,980 --> 00:34:25,300 Looks like number two is up for you, man. 566 00:34:25,300 --> 00:34:28,220 With the same number of wildcarts. 567 00:34:28,220 --> 00:34:33,660 But by studying the dynamics of the queue, Jamie's already spotted something serious. 568 00:34:33,660 --> 00:34:39,100 So the amount of time that it took that customer to get from the middle of the line to the 569 00:34:39,100 --> 00:34:44,620 cashier is time that didn't exist if that person was standing in line the conventional 570 00:34:44,620 --> 00:34:45,620 way. 571 00:34:45,620 --> 00:34:50,500 That travel distance that I think has to be making this whole thing take more time. 572 00:34:50,500 --> 00:34:55,660 According to the Heinemann, this extra travel to the till will slow the system. 573 00:34:55,660 --> 00:34:57,520 But Adam's not so sure. 574 00:34:57,520 --> 00:35:01,060 When we first started writing out the methodology for this test, I have to tell you I had some 575 00:35:01,060 --> 00:35:04,060 bias and I thought serpentine was totally going to win. 576 00:35:04,060 --> 00:35:08,820 But now after watching this in action, I'm not so sure that I'm right about that because 577 00:35:08,820 --> 00:35:14,700 it may be that this just makes it fairer for everybody but not necessarily faster for 578 00:35:14,780 --> 00:35:15,780 everybody. 579 00:35:15,780 --> 00:35:16,780 Price check on two. 580 00:35:16,780 --> 00:35:18,780 Oh, price check on two. 581 00:35:18,780 --> 00:35:19,780 Excuse me. 582 00:35:19,780 --> 00:35:20,780 Still to come. 583 00:35:20,780 --> 00:35:22,300 Jamie shops for signs. 584 00:35:22,300 --> 00:35:27,700 It's a good known fact that Heinemann can live for months on nothing but eggs and beer. 585 00:35:27,700 --> 00:35:30,700 And Adam goes in for the kill. 586 00:35:30,700 --> 00:35:32,700 Prove me. 587 00:35:32,700 --> 00:35:36,700 Here, yes, yes, ah! 588 00:35:36,700 --> 00:35:42,700 To celebrate this farewell season, this is Mythbusters by the Numbers. 589 00:35:43,700 --> 00:35:56,700 From viewers with terrific talents to hordes of human guinea pigs, the Mythbusters have 590 00:35:56,700 --> 00:36:05,700 relied on audience participation for 14 years in change. 591 00:36:05,700 --> 00:36:11,700 So to all our 3,500 intrepid volunteers, we literally 592 00:36:12,700 --> 00:36:14,700 couldn't have done it without you. 593 00:36:14,700 --> 00:36:18,700 Yo, I'm Jesse Pikman and it's time to science this Bia chop. 594 00:36:27,700 --> 00:36:32,700 Adam and Jamie are testing a super story about the Superstore. 595 00:36:32,700 --> 00:36:38,700 Is it better to line up in individual lanes or in one long line? 596 00:36:38,700 --> 00:36:45,700 Halfway through the long line test and their Mythbust store data is coming in in droves, 597 00:36:45,700 --> 00:36:48,700 which is Jamie's cue to join in. 598 00:36:48,700 --> 00:36:50,700 It's time for you to be a customer. 599 00:36:50,700 --> 00:36:51,700 Okay. 600 00:36:51,700 --> 00:36:53,700 Like Adam before him, 10 items. 601 00:36:53,700 --> 00:36:56,700 Jamie's volunteered to collect data. 602 00:36:56,700 --> 00:36:58,700 Fresh produce is good for you. 603 00:36:58,700 --> 00:37:01,700 As he sources a randomly allocated 10 items. 604 00:37:01,700 --> 00:37:04,700 And some peanut butter. 605 00:37:04,700 --> 00:37:09,700 Before standing in line, which is too hard for Adam to resist. 606 00:37:09,700 --> 00:37:11,700 Yes, yes, yes, yes. 607 00:37:11,700 --> 00:37:17,700 You can see him that he's blending in with the average populace, not even a little bit. 608 00:37:17,700 --> 00:37:23,700 You can spot him by his absurd mustache and self-referential hat. 609 00:37:23,700 --> 00:37:31,700 Whereas Adam Attenborough Savage cued for 3 minutes 18, Jamie's wait is way longer, 610 00:37:31,700 --> 00:37:33,700 a whopping 5 minutes 29. 611 00:37:33,700 --> 00:37:34,700 There you go. 612 00:37:34,700 --> 00:37:36,700 Keep the change. 613 00:37:36,700 --> 00:37:39,700 But that's still less than the Piccolane average. 614 00:37:39,700 --> 00:37:41,700 So what will the rest of the data say? 615 00:37:41,700 --> 00:37:49,700 Well, 6 minutes and 32 transactions later, the guys have all the numbers they need. 616 00:37:49,700 --> 00:37:51,700 All right, everybody, freeze where you are. 617 00:37:51,700 --> 00:37:52,700 Freeze where you are. 618 00:37:52,700 --> 00:37:54,700 That will conclude test number two. 619 00:37:54,700 --> 00:37:55,700 You guys are awesome. 620 00:37:55,700 --> 00:37:56,700 Thank you. 621 00:37:56,700 --> 00:37:59,700 Give it a great jump. 622 00:38:00,700 --> 00:38:03,700 All right, the results of our serpentine tests are in. 623 00:38:03,700 --> 00:38:10,700 And if you remember, the average wait time for our five individual lane shoppers was 5 minutes and 39 seconds. 624 00:38:10,700 --> 00:38:16,700 The average wait time for the serpentine shoppers was 6 minutes and 56 seconds. 625 00:38:16,700 --> 00:38:22,700 Yes, 77 seconds on average per shopper slower. 626 00:38:22,700 --> 00:38:23,700 What the hey? 627 00:38:23,700 --> 00:38:25,700 That's absolutely kind of mind-blowing to me. 628 00:38:25,700 --> 00:38:26,700 That's right. 629 00:38:26,700 --> 00:38:28,700 But here's where it gets interesting. 630 00:38:28,700 --> 00:38:33,700 Even though the serpentine moved slower, the customers actually liked it better. 631 00:38:33,700 --> 00:38:37,700 In fact, twice as many gave it a five the top rating. 632 00:38:37,700 --> 00:38:39,700 Go figure. 633 00:38:39,700 --> 00:38:43,700 It's a result that's the complete opposite of the myth. 634 00:38:43,700 --> 00:38:47,700 The serpentine was slower, yet also more popular. 635 00:38:47,700 --> 00:38:49,700 And Adam thinks he knows why. 636 00:38:49,700 --> 00:38:52,700 So why is serpentine slower? 637 00:38:52,700 --> 00:38:54,700 Well, let's look at the individual lines first. 638 00:38:54,700 --> 00:38:58,700 The fastest time through those lines was 2 minutes and 16 seconds. 639 00:38:58,700 --> 00:38:59,700 That is blazing fast. 640 00:38:59,700 --> 00:39:01,700 No bogies, quick cashier. 641 00:39:01,700 --> 00:39:02,700 Everyone's happy. 642 00:39:02,700 --> 00:39:07,700 But our fastest time in the serpentine was almost twice as slow, 4 minutes and 33 seconds. 643 00:39:07,700 --> 00:39:12,700 That's because the speed of the lines is averaged out across the entire group. 644 00:39:12,700 --> 00:39:13,700 And it brings it down. 645 00:39:13,700 --> 00:39:18,700 And when you add in the length of time it takes to get from the end of the line over to the next available cashier, 646 00:39:18,700 --> 00:39:22,700 well, it turns out you've added almost a minute to everyone's time. 647 00:39:22,700 --> 00:39:23,700 That's pretty amazing. 648 00:39:23,700 --> 00:39:25,700 Yep, it's slower for sure. 649 00:39:25,700 --> 00:39:29,700 But because it's also fairer, it's got the volunteer thumbs up. 650 00:39:34,700 --> 00:39:37,700 So how to call this myth is actually kind of interesting. 651 00:39:37,700 --> 00:39:38,700 How so? 652 00:39:38,700 --> 00:39:43,700 Well, the myth as stated is that the serpentine method, the single long line is faster. 653 00:39:43,700 --> 00:39:46,700 And the implication is that it's therefore better. 654 00:39:46,700 --> 00:39:47,700 Right. 655 00:39:47,700 --> 00:39:50,700 But even though we found it was 23% slower. 656 00:39:50,700 --> 00:39:51,700 The customers liked it better. 657 00:39:51,700 --> 00:39:55,700 Yeah, so we're in this weird position of saying serpentine method is busted. 658 00:39:55,700 --> 00:39:56,700 But it's also better. 659 00:39:56,700 --> 00:39:57,700 Yeah, busted but better. 660 00:39:57,700 --> 00:39:58,700 That's cool. 661 00:39:58,700 --> 00:39:59,700 Let's get out of here. 662 00:39:59,700 --> 00:40:00,700 Okay. 663 00:40:09,700 --> 00:40:11,700 Back at their apocalyptic location. 664 00:40:12,700 --> 00:40:15,700 It's time for this last season's last stand. 665 00:40:16,700 --> 00:40:19,700 Against the zombies ultimate nemesis. 666 00:40:23,700 --> 00:40:31,700 But will the legendary chainsaw beat the course record of 67 kills? 667 00:40:31,700 --> 00:40:32,700 Okay, Adam. 668 00:40:32,700 --> 00:40:35,700 Three, two, one, go. 669 00:40:35,700 --> 00:40:38,700 Remember, Adam's rigged his replica. 670 00:40:38,700 --> 00:40:40,700 Zombie blood all over me. 671 00:40:40,700 --> 00:40:44,700 With a switch that lets him kill a zombie in three quarters of a second. 672 00:40:44,700 --> 00:40:46,700 Come on, come on, zombies, yes. 673 00:40:46,700 --> 00:40:52,700 Which means he's able to rack up his score faster than a death metal montage. 674 00:40:52,700 --> 00:40:53,700 Oh, yes. 675 00:40:53,700 --> 00:40:56,700 Oh, this is awesome. 676 00:40:56,700 --> 00:40:59,700 Ah, ah, ah. 677 00:40:59,700 --> 00:41:00,700 Yes. 678 00:41:00,700 --> 00:41:02,700 Oh, this is awesome. 679 00:41:02,700 --> 00:41:06,700 Ah, ah, ah, yes. 680 00:41:06,700 --> 00:41:09,700 Ah, ah, ah. 681 00:41:09,700 --> 00:41:12,700 With minimal reset time and little fatigue. 682 00:41:12,700 --> 00:41:15,700 Ah, oh, I'm falling into zombies. 683 00:41:15,700 --> 00:41:21,700 It's only four manic minutes until Adam is the last man standing. 684 00:41:21,700 --> 00:41:26,700 Ah, ah, ah, yes. 685 00:41:26,700 --> 00:41:28,700 Woo. 686 00:41:28,700 --> 00:41:32,700 I killed all the zombies. 687 00:41:32,700 --> 00:41:36,700 It's a final season scene of utter devastation. 688 00:41:36,700 --> 00:41:42,700 All 190 zombie volunteers are dead and buried. 689 00:41:42,700 --> 00:41:45,700 It's been a few decades since I was a mediocre student, 690 00:41:45,700 --> 00:41:50,700 but I remember enough to remember that a really good score is 100%. 691 00:41:50,700 --> 00:41:54,700 That's how many zombies I killed, and it feels good. 692 00:41:55,700 --> 00:41:58,700 With a success rate that's second to none, 693 00:41:58,700 --> 00:42:04,700 the chainsaw status as the ultimate end of the world weapon is well and truly confirmed. 694 00:42:04,700 --> 00:42:09,700 But that's not the only top tip from the misbusters. 695 00:42:09,700 --> 00:42:12,700 So after all that we've learned with dealing with zombies, 696 00:42:12,700 --> 00:42:14,700 what's your plan in the zombie apocalypse? 697 00:42:14,700 --> 00:42:16,700 Run.
