I'm ready. 249 00:12:59,000 --> 00:13:04,000 MUSIC 250 00:13:04,000 --> 00:13:10,000 Twelve feet away from one pound of exploding C4 will result in serious injury. 251 00:13:10,000 --> 00:13:15,000 But Hollywood would have us believe you could walk away unscathed. 252 00:13:15,000 --> 00:13:17,000 You got this from Jamie's office? 253 00:13:17,000 --> 00:13:23,000 By dropping the ticking time bomb in a handily located, supposedly boom-proof container. 254 00:13:23,000 --> 00:13:26,000 I'm trying to find my contract right now. 255 00:13:26,000 --> 00:13:28,000 Like a filing cabinet. 256 00:13:28,000 --> 00:13:34,000 Okay, so this is our same 13 PSI injury indicating burst disc. 257 00:13:34,000 --> 00:13:39,000 I don't remember agreeing to washing Jamie's mustache. 258 00:13:39,000 --> 00:13:47,000 And remember, with no containment devices, one pound of C4 caused this disc to go off at this 12-foot range. 259 00:13:49,000 --> 00:13:52,000 Well, I'll be damned. I guess I have to wash his mustache. 260 00:13:53,000 --> 00:14:00,000 The goal here is to see if the containment devices serve as some kind of protection. 261 00:14:00,000 --> 00:14:05,000 And to indicate that, if this disc does not go off, then that means, you know what? 262 00:14:05,000 --> 00:14:08,000 There's no injury at this range, and they did their job. 263 00:14:08,000 --> 00:14:13,000 You're probably asking yourself, why do you guys have these Styrofoam cut out blue guys? 264 00:14:13,000 --> 00:14:19,000 Well, those are our shrapnel catchers, because if the shockwave doesn't injure you, the shrapnel might. 265 00:14:19,000 --> 00:14:23,000 In three, two, one. 266 00:14:25,000 --> 00:14:27,000 Oh, my God, your files. 267 00:14:27,000 --> 00:14:29,000 Wow! 268 00:14:29,000 --> 00:14:31,000 That is a mess of paper. 269 00:14:34,000 --> 00:14:36,000 It's just confetti. 270 00:14:36,000 --> 00:14:38,000 Alright, let's see if it helps. 271 00:14:41,000 --> 00:14:46,000 Well, as far as the pressure wave goes, the filing cabinet did offer some protection. 272 00:14:46,000 --> 00:14:51,000 The disc at 12 feet, the dive to survive zone, did not burst. 273 00:14:52,000 --> 00:14:56,000 Okay, so the cabinet did save you from the shockwave, but you're going to be killed by the shrapnel. 274 00:14:56,000 --> 00:14:59,000 I mean, look at that guy's head. It's been ripped off. 275 00:14:59,000 --> 00:15:02,000 Oh, putting the ball in the filing cabinet. 276 00:15:04,000 --> 00:15:06,000 What was I thinking? 277 00:15:17,000 --> 00:15:19,000 Will you take this? 278 00:15:19,000 --> 00:15:21,000 Now we're going to move on to a bed. 279 00:15:21,000 --> 00:15:25,000 Ooh, I kind of want some red silky sheets now. This is nice. 280 00:15:25,000 --> 00:15:27,000 Ooh, these are fancy. 281 00:15:27,000 --> 00:15:32,000 Now you might be asking yourself, how would you use a bed to protect yourself from an explosion? 282 00:15:32,000 --> 00:15:34,000 Cue the dream sequence. 283 00:15:34,000 --> 00:15:37,000 Wait for this. This is a little disturbing. 284 00:15:46,000 --> 00:15:48,000 Ah! Ah! 285 00:15:52,000 --> 00:15:54,000 That could work. 286 00:15:54,000 --> 00:15:58,000 Here we go. In three, two, one. 287 00:16:04,000 --> 00:16:10,000 That's really interesting. All the energy went up and I didn't see any shrapnel go out towards the guys. 288 00:16:11,000 --> 00:16:16,000 I will be so shocked if stuffing a bomb under your bed actually saves you. 289 00:16:16,000 --> 00:16:19,000 You've got to be kidding me. 290 00:16:19,000 --> 00:16:22,000 I think we might have found something that's actually bomb proof. 291 00:16:22,000 --> 00:16:25,000 Yeah, I mean, look, the burst discs aren't even burst. 292 00:16:25,000 --> 00:16:28,000 And the shrapnel catchers? 293 00:16:28,000 --> 00:16:32,000 Well, they caught nothing but a gentle rain of mattress stuffing. 294 00:16:32,000 --> 00:16:37,000 I'm absolutely astounded at how well the mattress worked at both absorbing the shockwave 295 00:16:37,000 --> 00:16:40,000 and preventing deadly shrapnel from hitting our guys. 296 00:16:40,000 --> 00:16:43,000 And if you look at the high speed, you'll see exactly why. 297 00:16:43,000 --> 00:16:46,000 All the energy went straight up into the air. 298 00:16:55,000 --> 00:17:01,000 But up next is a fish tank full of water, and that is a totally different animal. 299 00:17:08,000 --> 00:17:12,000 Welcome back. It's guns versus grenades on mythbusters. 300 00:17:12,000 --> 00:17:19,000 And truth be told, if someone has just thrown one of these at you and you have enough time to see it 301 00:17:19,000 --> 00:17:22,000 and pull a gun to try and shoot at it, pull. 302 00:17:22,000 --> 00:17:26,000 Kind of gun you're going to have ready access to. It's going to be something like this. 303 00:17:26,000 --> 00:17:31,000 But unlike a shotgun, this only fires a single round, a single piece of lead. 304 00:17:31,000 --> 00:17:35,000 Can you even hit this in midair with this? 305 00:17:35,000 --> 00:17:37,000 Well, that's what Jamie and I are about to try and find out. 306 00:17:37,000 --> 00:17:40,000 We've chosen this spot because it's miles away from habitation. 307 00:17:40,000 --> 00:17:45,000 But even so, we're allowed to shoot anything straight up in the air other than bird shot. 308 00:17:45,000 --> 00:17:50,000 And with that in mind, we've chosen paintball pistols to do our test. 309 00:17:50,000 --> 00:17:56,000 Because if we can hit them with those, we should be able to hit them with a real pistol. 310 00:17:56,000 --> 00:17:59,000 All right, sir. I'm ready. 311 00:17:59,000 --> 00:18:01,000 Equally? 312 00:18:01,000 --> 00:18:05,000 Okay, here we go. Throw in the grenade in three. 313 00:18:05,000 --> 00:18:10,000 If they miss with the paintball pistol, they're likely to miss with a real one. 314 00:18:14,000 --> 00:18:17,000 Totally missed it. Let's try again. 315 00:18:17,000 --> 00:18:22,000 The myth is hitting its first hurdle. 316 00:18:22,000 --> 00:18:26,000 Because Adams certainly not hitting any grenades. 317 00:18:32,000 --> 00:18:37,000 I ran out of ammo. I got close, though. 318 00:18:37,000 --> 00:18:42,000 They've proven the wide spray of shotgun shot works. 319 00:18:42,000 --> 00:18:50,000 But the silver screen scene in question usually involves a weapon firing a single bullet at a time. 320 00:18:50,000 --> 00:18:56,000 And that's proving very, very difficult. 321 00:18:57,000 --> 00:19:00,000 Oh! I got it! 322 00:19:00,000 --> 00:19:04,000 But not impossible. 323 00:19:04,000 --> 00:19:08,000 There is paintball paint on that puppy. 324 00:19:08,000 --> 00:19:09,000 It can be done. 325 00:19:09,000 --> 00:19:12,000 It can be done. It can be done. 326 00:19:12,000 --> 00:19:14,000 I'm ready. 327 00:19:17,000 --> 00:19:23,000 Look, if someone's throwing a grenade at me, I'm going to use anything at my disposal to try and save my life. 328 00:19:23,000 --> 00:19:31,000 If that means fruitlessly shooting a whole clip of rounds at that thing with a 1% chance of hitting it... 329 00:19:33,000 --> 00:19:35,000 I got it. 330 00:19:35,000 --> 00:19:38,000 I'm going to take those odds. Nice! 331 00:19:38,000 --> 00:19:41,000 Right in the middle. Beautiful. 332 00:19:43,000 --> 00:19:48,000 But the real question is what happens to a grenade when you hit it with a real bullet? 333 00:19:48,000 --> 00:19:51,000 That's the question we're going to answer next. 334 00:19:53,000 --> 00:20:03,000 We're testing different household items that can mythically contain the blast of a bomb. 335 00:20:03,000 --> 00:20:05,000 You've got to be kidding me. 336 00:20:05,000 --> 00:20:10,000 This test, we're using a pound of C4 and we're throwing it inside of a fish tank. 337 00:20:10,000 --> 00:20:12,000 Candy Graham. 338 00:20:15,000 --> 00:20:21,000 To measure it all, we have our Oseco burst discs and our shrapnel catchers. 339 00:20:21,000 --> 00:20:27,000 This will tell us if a fish tank is enough to take on one pound of C4. 340 00:20:27,000 --> 00:20:30,000 So what do I think is going to happen here? 341 00:20:30,000 --> 00:20:35,000 Well, I see an incompressible fluid surrounded by a 3 eighth inch acrylic tank. 342 00:20:35,000 --> 00:20:39,000 The water is not going to really absorb the explosion. 343 00:20:39,000 --> 00:20:47,000 Rather, it's going to transmit that out to the edges of the tank, which is going to shatter into a million razor sharp acrylic pieces. 344 00:20:48,000 --> 00:20:51,000 In three, two, one. 345 00:20:55,000 --> 00:20:58,000 Oh my god, that was awesome. 346 00:21:04,000 --> 00:21:09,000 That did not look good for our diving would-be survivor. But what's the evidence say? 347 00:21:09,000 --> 00:21:12,000 Wow. That was spectacular. 348 00:21:12,000 --> 00:21:14,000 Dude, look at this mess. 349 00:21:15,000 --> 00:21:18,000 The damage is not nearly what I thought it was going to be. 350 00:21:18,000 --> 00:21:23,000 And the Oseco disc survived, which means our hero would have survived the shock wave. 351 00:21:25,000 --> 00:21:30,000 Yeah, and look at the guys. I mean, there's no shrapnel in them. They look relatively unharmed. 352 00:21:33,000 --> 00:21:35,000 I think all of us are pretty surprised by this result. 353 00:21:35,000 --> 00:21:42,000 We thought this was going to shred and they're just be fragging shrapnel and all our guys, but that's not what happened. 354 00:21:42,000 --> 00:21:47,000 They look like all of the energy was focused on the front and the back of the tank, which was elevated. 355 00:21:47,000 --> 00:21:52,000 So if you hit the deck, you might walk away from the sun's scathe. 356 00:21:52,000 --> 00:21:55,000 I think we can actually call this plausible. 357 00:21:55,000 --> 00:21:57,000 Agreed. I think it's plausible as well. 358 00:21:57,000 --> 00:21:58,000 Shocking. 359 00:21:58,000 --> 00:22:00,000 That was awesome. 360 00:22:00,000 --> 00:22:15,000 Welcome to Angels Camp Quarry, because next up, the team is ramping it up. 361 00:22:15,000 --> 00:22:21,000 Now, what's the scenario? That's right. It's a garbage truck. 362 00:22:21,000 --> 00:22:27,000 Imagine this. It's early in the morning. You go to your mailbox and you find- 363 00:22:27,000 --> 00:22:33,000 What is it? A bomb? What am I going to do with it? Oh, I know. It's trash day. 364 00:22:33,000 --> 00:22:34,000 Road in the garbage truck. 365 00:22:34,000 --> 00:22:42,000 Now he has two options. He can jump away from the truck, dive here, or he can jump off to the side and let this steel wall protect it. 366 00:22:42,000 --> 00:22:44,000 Because of that, we're going to have two different setups. 367 00:22:44,000 --> 00:22:49,000 We're going to have a shrapnel catcher with the burst disc here and another shrapnel catcher with the burst disc here. 368 00:22:49,000 --> 00:22:52,000 It's to see whether or not this garbage truck will protect it. 369 00:22:53,000 --> 00:22:59,000 Alright, here we go with one pound of C4 in the trough of a garbage truck. 370 00:22:59,000 --> 00:23:05,000 In three, two, one, fire! 371 00:23:10,000 --> 00:23:13,000 Yeah, that's a pretty big pop. 372 00:23:13,000 --> 00:23:26,000 Well, I think it's obvious you don't want to stand behind the truck. This guy's blown to bits and the seco disc is blown. 373 00:23:26,000 --> 00:23:33,000 Alright, well, over here on the side, looks like you'd fare a whole lot better. In fact, you'd survive without injury. 374 00:23:33,000 --> 00:23:36,000 If you jump off to the side, you would survive. 375 00:23:39,000 --> 00:23:41,000 This one's looking plausible. 376 00:23:41,000 --> 00:23:43,000 So plausible by proximity. 377 00:23:48,000 --> 00:23:50,000 So what have we learned from this experiment? 378 00:23:50,000 --> 00:23:57,000 Well, when selecting a household item as a potential bomb disposal area, it's important to look at where the energy is going to go. 379 00:23:57,000 --> 00:24:00,000 Completely containing all that energy is a very bad idea. 380 00:24:00,000 --> 00:24:06,000 But if you find an item that can focus the energy in one direction, like the mattress or the aquarium, 381 00:24:06,000 --> 00:24:15,000 or in the garbage truck, and you jump away from that direction and hit the deck, you significantly increase your chances of survival. 382 00:24:15,000 --> 00:24:22,000 You guys, we're here, we have a truck, we have experts, and we have a lot of explosives. I say we do this myth buster style. 383 00:24:22,000 --> 00:24:23,000 Let's make it disappear. 384 00:24:23,000 --> 00:24:25,000 It's time to go boom. 385 00:24:25,000 --> 00:24:29,000 Fire in the hole! Fire in the hole! Fire in the hole! 386 00:24:29,000 --> 00:24:35,000 Five, four, three, two, one! 387 00:24:37,000 --> 00:24:43,000 Please do not try what you're about to see at home. 388 00:24:43,000 --> 00:24:46,000 The things that we do on this show are extremely dangerous. 389 00:24:46,000 --> 00:24:48,000 We have experts to keep us safe. 390 00:24:52,000 --> 00:24:53,000 Pull! 391 00:24:57,000 --> 00:25:00,000 We're done with our target practice on fake grenades. 392 00:25:02,000 --> 00:25:04,000 So now it's time to break out the real ones. 393 00:25:06,000 --> 00:25:08,000 It looks pretty innocuous, doesn't it? 394 00:25:08,000 --> 00:25:13,000 It is, in fact, pretty small compared to some of the things we've blown up over the history of myth busters. 395 00:25:18,000 --> 00:25:26,000 But in fact, these grenades are incredibly dangerous and have all of us in our bomb techs quite nervous. 396 00:25:26,000 --> 00:25:33,000 So in order to properly experiment with these, we have come to a large tract of private land in Gold Country, east of the Myth Busters shop. 397 00:25:33,000 --> 00:25:40,000 We have thousands of acres of clear land all around us in order to experiment with these. 398 00:25:41,000 --> 00:25:43,000 God, I love operating the big machinery. 399 00:25:47,000 --> 00:25:54,000 Countless times on this show, we have armored ourselves behind these blast chamber panels to watch dangerous things happen, hopefully right on the other side. 400 00:25:54,000 --> 00:25:56,000 Perfect. That's perfect. I love it. 401 00:25:56,000 --> 00:26:03,000 This is the setup where our blast chamber panel is bordered on both sides by inch thick plates of steel. 402 00:26:03,000 --> 00:26:07,000 This is the most armored we have ever required ourselves to be out in the field. 403 00:26:08,000 --> 00:26:12,000 That's because it's not just an explosive pressure wave they're dealing with. 404 00:26:13,000 --> 00:26:22,000 The steel body of the grenade is designed to spray lethal fragments at over 25,000 feet per second in every direction. 405 00:26:22,000 --> 00:26:30,000 And the nightmare scenario is a misfire. To prepare for that, Jamie's recreated his own nightmare. 406 00:26:30,000 --> 00:26:38,000 Normally, bomb disposal robots cost around 100 grand or so. This is my version. Behold the bomb, baby. 407 00:26:38,000 --> 00:27:04,000 This is about a $200 remote control truck. I put some servos for arms, a baby head, and most importantly, through this camera, I'll be able to see what's going on from the safety of our reinforced bunker. 408 00:27:08,000 --> 00:27:14,000 Those are the safety precautions. But what's the first test? Time to wire up a little control. 409 00:27:15,000 --> 00:27:19,000 Before we get to shooting guns at these things, they have a timed fuse. 410 00:27:19,000 --> 00:27:21,000 All right, go ahead and make it go up. 411 00:27:21,000 --> 00:27:28,000 I.e., after you pull the pin and release the spoon, there's a few seconds before they blow up. How many seconds? 412 00:27:29,000 --> 00:27:35,000 That's what we need to determine by blowing one up. I knew that was a dead. 413 00:27:36,000 --> 00:27:48,000 But this one isn't. Blame the bomb tech pulls the pin and then traps the spoon of the live grenade in the tube. When it's raised, the spoon will pop and we're hot. 414 00:27:48,000 --> 00:27:54,000 The delay fuse will light and we'll find out exactly how long it takes a grenade to go boom. 415 00:27:54,000 --> 00:27:56,000 I feel quite tense about this. 416 00:27:56,000 --> 00:27:57,000 We're all ready? 417 00:27:57,000 --> 00:27:58,000 Yep. 418 00:27:58,000 --> 00:28:02,000 Everybody's clear? Here we go. Going up. 419 00:28:05,000 --> 00:28:12,000 I heard the cap go. 420 00:28:12,000 --> 00:28:16,000 Wow. 421 00:28:16,000 --> 00:28:19,000 I heard stuff hit us. 422 00:28:19,000 --> 00:28:23,000 That was intense, man. 423 00:28:36,000 --> 00:28:47,000 The key reason for this test was to check our timing because we need to know how much time it takes for the grenade to go off once the spoon pops up. 424 00:28:47,000 --> 00:28:50,000 That was five seconds exactly. 425 00:28:50,000 --> 00:28:54,000 Time for some guns. 426 00:28:54,000 --> 00:29:04,000 We're just about to start firing guns at grenades and we've been thinking about it and we think one of three things is going to happen for each of these shots. 427 00:29:04,000 --> 00:29:09,000 Either the round will render the grenade inert and maybe decimate it. That's one. 428 00:29:09,000 --> 00:29:13,000 Two is it could actually detonate it and explode it in midair. 429 00:29:13,000 --> 00:29:18,000 Or three, it could bring enough energy to the equation to actually send the grenade back to where it came. 430 00:29:18,000 --> 00:29:21,000 I'm curious as to what the result is actually going to be. 431 00:29:21,000 --> 00:29:26,000 To find out the setup is simple. 432 00:29:26,000 --> 00:29:28,000 Alright then. 433 00:29:28,000 --> 00:29:35,000 It's been established an oncoming grenade can be taken out, but with live ammo they're taking no chances. 434 00:29:35,000 --> 00:29:39,000 Three, two, one, go. 435 00:29:39,000 --> 00:29:40,000 Perfect. 436 00:29:40,000 --> 00:29:46,000 These are the weapons we'll be using on our grenade today and we'll be firing four kinds of ammunition out of these three weapons. 437 00:29:46,000 --> 00:29:53,000 We've got a .308 round, a .45 caliber pistol round and a 12 gauge double-aught buck round. 438 00:29:53,000 --> 00:29:59,000 That looks pretty dead on. I'll leave the rest to the bomb squad. 439 00:29:59,000 --> 00:30:07,000 Now here's where things get interesting. I think the .308 round is going to be by far the most effective round against the grenade. 440 00:30:07,000 --> 00:30:12,000 But its rifle is by far the most difficult one to hit a grenade in midair with. 441 00:30:12,000 --> 00:30:19,000 While at the other end of the spectrum we've got the shotgun used for trap shooting, the easiest weapon to use to hit a grenade in midair. 442 00:30:19,000 --> 00:30:24,000 But I think this, the double-aught buck round, will be the least effective against the grenade. 443 00:30:24,000 --> 00:30:28,000 First up, the shotgun and the lightweight buck shot. 444 00:30:28,000 --> 00:30:31,000 Okay. 445 00:30:31,000 --> 00:30:33,000 Arming. 446 00:30:33,000 --> 00:30:36,000 Will it detonate the electronically triggered grenade? 447 00:30:36,000 --> 00:30:38,000 Arms. 448 00:30:38,000 --> 00:30:39,000 Or render it inert? 449 00:30:39,000 --> 00:30:40,000 Three. 450 00:30:40,000 --> 00:30:43,000 Or even knock it back 30 feet. 451 00:30:43,000 --> 00:30:44,000 Two. 452 00:30:44,000 --> 00:30:48,000 Cartoon style. 453 00:30:48,000 --> 00:30:53,000 One. Fire. 454 00:30:53,000 --> 00:30:55,000 Where'd it go? 455 00:30:55,000 --> 00:30:57,000 I don't know. 456 00:30:57,000 --> 00:30:58,000 It didn't go off. 457 00:30:58,000 --> 00:31:00,000 Crap. 458 00:31:00,000 --> 00:31:01,000 Yeah. 459 00:31:01,000 --> 00:31:03,000 We've got ourselves a situation now. 460 00:31:03,000 --> 00:31:10,000 The grenade's delay fuse was remotely triggered, Adam fired the shotgun and the grenade was knocked off the stand. 461 00:31:10,000 --> 00:31:13,000 But there was no explosion. 462 00:31:13,000 --> 00:31:18,000 And now somewhere out there we have a live grenade. 463 00:31:18,000 --> 00:31:22,000 We cannot leave this bunker until we deal with this situation. You want to fire up the baby? 464 00:31:22,000 --> 00:31:25,000 The Garbage Truck 465 00:31:30,000 --> 00:31:34,000 Turns out that the garbage truck is plausible. 466 00:31:34,000 --> 00:31:37,000 Our hero would have survived that blast. 467 00:31:37,000 --> 00:31:43,000 But now it's my favorite time where we ramp it up and see if we can make that garbage truck not so bombproof. 468 00:31:43,000 --> 00:31:49,000 So we're going to load it up with 200 pounds of Ampho. See if we can make this thing disappear. 469 00:31:49,000 --> 00:31:51,000 Now does this remind you of anything? 470 00:31:51,000 --> 00:31:54,000 This is like cement truck all over again. 471 00:31:54,000 --> 00:31:57,000 And this is the quarry where we actually blew it up. 472 00:32:00,000 --> 00:32:05,000 Now one thing everybody complains about is you guys don't have a high speed shot. 473 00:32:05,000 --> 00:32:09,000 We don't have to worry about that this time. We have our high speed camera standing by and we're going to get that shot. 474 00:32:09,000 --> 00:32:11,000 In that right, Willie. 475 00:32:12,000 --> 00:32:14,000 No pressure. 476 00:32:21,000 --> 00:32:23,000 The Garbage Truck 477 00:32:30,000 --> 00:32:33,000 This is Garbage Truck versus a whole lot of Ampho. 478 00:32:35,000 --> 00:32:37,000 In three. 479 00:32:39,000 --> 00:32:40,000 Two. 480 00:32:41,000 --> 00:32:42,000 One. 481 00:32:45,000 --> 00:32:46,000 Whoa! 482 00:32:46,000 --> 00:32:48,000 Oh my God! 483 00:32:52,000 --> 00:32:58,000 The Shrangle got up to the same height as us! 484 00:32:59,000 --> 00:33:01,000 Whoa! 485 00:33:04,000 --> 00:33:07,000 That was intense. 486 00:33:07,000 --> 00:33:09,000 Now that's an explosion. 487 00:33:11,000 --> 00:33:16,000 No CGI. No unlikely survivors. Just a whole load of... 488 00:33:17,000 --> 00:33:23,000 Big boom in glorious 5,000 frames a second high speed. 489 00:33:23,000 --> 00:33:26,000 Wow! Way to wrap things up guys. 490 00:33:26,000 --> 00:33:28,000 Well that's one way to take out the trash. 491 00:33:28,000 --> 00:33:30,000 You know what the best part about all this is? 492 00:33:30,000 --> 00:33:35,000 Through the magic of editing we can watch this experiment over and over again. 493 00:33:46,000 --> 00:33:48,000 The Shrangle 494 00:33:56,000 --> 00:34:00,000 Since this story is about grenades, I'm going to map out how these things work. 495 00:34:00,000 --> 00:34:07,000 This thing on the outside is called the Spoon and it's retained by this ring and a pin. 496 00:34:07,000 --> 00:34:14,000 Now underneath that is a spring-loaded striker which once the Spoon is released, the striker is also released 497 00:34:14,000 --> 00:34:18,000 and it flips over and creates a spark like so. 498 00:34:18,000 --> 00:34:26,000 Underneath that spark is a fuse. It's called a delay fuse which is engineered to burn for a specific period of time. 499 00:34:26,000 --> 00:34:36,000 Once it burns to its end which is down somewhere in the middle of the grenade, it ignites a small amount of high explosive that's relatively unstable. 500 00:34:36,000 --> 00:34:41,000 That creates a small blast which ignites the rest of the high explosive that fills the grenade. 501 00:34:41,000 --> 00:34:48,000 At this point you basically got a small pipe bomb which has a kill zone of about 45 feet. 502 00:34:52,000 --> 00:34:53,000 Fire! 503 00:34:56,000 --> 00:34:57,000 Where'd it go? 504 00:34:57,000 --> 00:34:58,000 It didn't go off. 505 00:34:59,000 --> 00:35:05,000 But why? Before they fire up the bomb baby, Adam fires up the high speed camera. 506 00:35:05,000 --> 00:35:07,000 Oh, crime-idy, Jamie, come here. 507 00:35:08,000 --> 00:35:09,000 Dude. 508 00:35:11,000 --> 00:35:12,000 Watch this. 509 00:35:15,000 --> 00:35:16,000 No more grenades. 510 00:35:17,000 --> 00:35:21,000 We don't have a live grenade out there. We've got a bunch of dust. 511 00:35:22,000 --> 00:35:23,000 Wow. 512 00:35:23,000 --> 00:35:24,000 I totally did not see that coming. 513 00:35:26,000 --> 00:35:28,000 Darn, I wanted to wake the baby up. 514 00:35:32,000 --> 00:35:33,000 That's a result. 515 00:35:33,000 --> 00:35:40,000 Unbelievably, it seems that you can indeed shoot a live grenade and render it inert. 516 00:35:41,000 --> 00:35:51,000 It's amazing. It disintegrated the outer casing and then even though this was in its five second range, did not let it explode the caps so the TNT didn't blow up. 517 00:35:51,000 --> 00:35:52,000 Wow. 518 00:35:52,000 --> 00:35:55,000 I would not have called that. That's amazing. 519 00:35:56,000 --> 00:36:10,000 The double-odd buck completely disintegrated the grenade and that frankly surprised us all because double-odd buck is their little 38 caliber lead balls and you wouldn't think it would be able to do a whole lot to a steel grenade. 520 00:36:10,000 --> 00:36:17,000 But it did. It took it completely apart and it even took apart the blasting cap before it could go off. 521 00:36:17,000 --> 00:36:26,000 An astonishing result. The fuse was lit electronically but before it could detonate, the buck shot broke up the TNT party. 522 00:36:30,000 --> 00:36:34,000 Next up is a 45 caliber round pointed at the grenade. 523 00:36:34,000 --> 00:36:43,000 If you remember, only very recently we discovered it's a lot harder to hit a mid-air grenade with one of these than it is with one of those easy shotgun rounds. 524 00:36:43,000 --> 00:36:46,000 As to what it's going to do to the grenade, you ready? 525 00:36:46,000 --> 00:36:51,000 Okay. 45 ACP. Three. 526 00:36:51,000 --> 00:36:55,000 I expect it to have a very similar effect as the double-odd buck. 527 00:36:55,000 --> 00:36:56,000 Two. 528 00:36:56,000 --> 00:37:00,000 I think that the 45 caliber round is going to turn that thing right into dust. 529 00:37:00,000 --> 00:37:02,000 One. Fire. 530 00:37:04,000 --> 00:37:07,000 Hey! It shot it right off the thing. 531 00:37:08,000 --> 00:37:10,000 The cap went off but the grenade didn't. 532 00:37:10,000 --> 00:37:13,000 We knocked the grenade off the stand. It looks like we split it in half. 533 00:37:13,000 --> 00:37:17,000 So we didn't stop the cap from going off but we did stop the grenade from blowing up. 534 00:37:17,000 --> 00:37:18,000 That's cool. 535 00:37:18,000 --> 00:37:19,000 That is very cool. 536 00:37:28,000 --> 00:37:34,000 Compared to the buck shot, the 45 millimeter round removed the blasting cap with surgical precision. 537 00:37:35,000 --> 00:37:39,000 Either way, it's another myth-confirming result. 538 00:37:39,000 --> 00:37:40,000 What's next? 539 00:37:48,000 --> 00:37:54,000 Now we're going to bring some real energy to the equation by using a .308 sniper round full metal jacket. 540 00:37:55,000 --> 00:37:56,000 There we go. 541 00:37:56,000 --> 00:38:01,000 As to what this is going to do to the grenade, I've been wrong for everything so far. 542 00:38:01,000 --> 00:38:04,000 So I'm going to say I have no freaking idea. 543 00:38:06,000 --> 00:38:09,000 Three, two, one. Fire. 544 00:38:11,000 --> 00:38:15,000 The grenade went boom. We didn't disintegrate it. It blew up. 545 00:38:17,000 --> 00:38:18,000 I think so. 546 00:38:20,000 --> 00:38:21,000 Let's look at high speed. 547 00:38:21,000 --> 00:38:22,000 Okay. 548 00:38:25,000 --> 00:38:29,000 The high speed camera, the scalpel, the microscope, the light, 549 00:38:29,000 --> 00:38:32,000 the multi-tool for tackling time. 550 00:38:32,000 --> 00:38:33,000 There it is. 551 00:38:33,000 --> 00:38:38,000 And what it shows is the grenade ignited the second thing it penetrated. 552 00:38:39,000 --> 00:38:40,000 That is a thing. 553 00:38:43,000 --> 00:38:47,000 The blasting cap inside a grenade is actually somewhat shock-sensitive. 554 00:38:47,000 --> 00:38:51,000 And the .308 round is a very, very high speed round. 555 00:38:51,000 --> 00:38:56,000 And that speed translates directly to a certain amount of energy being brought to the equation. 556 00:38:56,000 --> 00:39:02,000 And in our case, the .308 round, the very instant it touched the exterior of our grenade, 557 00:39:02,000 --> 00:39:06,000 that shock caused the entire thing to detonate early. 558 00:39:06,000 --> 00:39:10,000 It was a very, very powerful reaction and an instant one. 559 00:39:11,000 --> 00:39:13,000 Yep, it's the second of three potential results. 560 00:39:14,000 --> 00:39:18,000 And the most common of the cinematic techniques, the mid-air explosion. 561 00:39:19,000 --> 00:39:21,000 But let's think about that for a second. 562 00:39:21,000 --> 00:39:26,000 Because if that ignited the grenade at any closer than 45 feet, 563 00:39:27,000 --> 00:39:30,000 which is the kill zone for a grenade, you're dead. 564 00:39:30,000 --> 00:39:37,000 Further than 45 feet, it starts to become almost impossible to make a shot like that. 565 00:39:38,000 --> 00:39:43,000 Yes, in theory it's possible, but I would duck. 566 00:39:43,000 --> 00:39:45,000 Personally, I would just duck. 567 00:39:49,000 --> 00:39:50,000 That worked! 568 00:39:50,000 --> 00:39:55,000 So to recap our final results, the high-powered rounds, the .308, 569 00:39:55,000 --> 00:40:01,000 actually detonated the grenade, which means that if it's within 50 feet of you, you're dead sucker. 570 00:40:01,000 --> 00:40:07,000 But the low-powered rounds, the .45, and especially the shotgun, both rendered the grenades inert. 571 00:40:07,000 --> 00:40:11,000 The shotguns even kept the blasting cap from going off. 572 00:40:11,000 --> 00:40:15,000 Pretty much the exact polar opposite of what we thought was going to happen. 573 00:40:15,000 --> 00:40:16,000 Isn't that cool? 574 00:40:21,000 --> 00:40:27,000 So where did we stand with the original question of whether you can protect yourself from a grenade using a gun? 575 00:40:27,000 --> 00:40:30,000 I think we found hand-lead that that is totally the case. 576 00:40:30,000 --> 00:40:36,000 Moreover, the weapon that rendered the grenade the most inert was the one that was easiest to shoot it out of the air with, the shotgun. 577 00:40:36,000 --> 00:40:38,000 Yep, so it's plausible. 578 00:40:38,000 --> 00:40:40,000 Totally plausible. Let's get out of here. 579 00:40:42,000 --> 00:40:43,000 Uh-oh. Bad baby. 580 00:40:43,000 --> 00:40:44,000 Run! 581 00:40:50,000 --> 00:40:51,000 Bad baby.
