    Fun fact, the concrete walls of the pentagon are actually coated in the exact bedliner they used. Specifically to protect against explosions. The high tensile strength of the compound works well with the high compressive strength of concrete.
    It got the coating in 2006. Just a few years before this episode was recorded.

      could it be, that the material underneath the coating is still cracked, but held together because of the coating and becoming more and more rubber-like material?

      ​@@martinvaldhans3679 I feel like thats possible maybe? But in the case of an explosion hitting it that doesn't just deglove the wall of its lining, they'd likely have the good sense to check for cracks afterward. In this scenario, the wall isnt coming down immediately either way, which is all its expected to do

    Remember folks: The reason a car crumples on impact is so that you don't; it's supposed to absorb/dissipate energy away from your body.
    The less damage the car takes or shows, the more damage you're probably receiving. Let the car rack up costs in repairs so that you don't have to pay it in the hospital.

    Louisville, KY beat this sewer explosion experiment by 43 years. Several hundred gallons of hexane were dumped in the sewer and set off by a car driving over a manhole cover at 6 am. A manhole cover narrowly missed hitting someone in bed, and several streets looked like they had been bombed.

      He wasn't actually the first mythbuster to die. Jessie, the woman who substituted for Karie for about a season and change while she was pregnant and during her maternity leave, died in a car crash a few years before Grant did. She specifically died trying to set a land speed record in a rocket car, if I'm remembering correctly.

      The blast from Even an anti personnel mine will crush civilian car bodywork like a beer can - dosen't matter what applied coatings it has on it. A no shit anti vehicle mine? Occupants have No chance at all.
      Now, if you painted the INTERIOR side of the car floor pan with a 1/4" thick layer of bed liner... that might catch any spall (pieces of the inside surface of the floor pan dislodged by the blast) from an anti personnel mine blast... but it won't stop any primary projectiles from the mine. And a mine intended to disable or destroy an armored vehicle? It'll do fuck all.
      BUT...
      fun fact - the interior of an armored vehicle is painted with a high build polyurea coating (it might actually BE a milspec line x product in fact) in some applications its also over over a kevlar fabric matrix it's called a "spall liner"
      That is designed to stop pieces of the interior side of the armor from getting dislodged from blast and killing the crew. Even if the armor isn't penetrated - the impact energy can propagate through the armor and break off a disc shaped chunk of the armor at a high enough velocity to kill crew members. Spall liners reduce this possibility
      If you shoot a BB at a thick piece of tempered glass - and it doesn't actually penetrate - but it busts off a cone shaped divot out of the inside surface of the glass? That's the same idea. That's spall.
      Bed liner isn't armor itself. But it can be a part of an armor system.

      ​@@kansaman1a lot of people have modeled it and found that it would have absolutely been destroyed very quickly. You're right that the heat from the nuke itself wouldn't have destroyed it, but when an object is going that fast, it compresses the air in front of it to a huge degree, generating incredible amounts of heat. That, combined with the enormous pressure generated by that collision with the air, would have torn it apart and basically atomized it. If you look up how heat shields for reentry from space work (which is the closest analog we have to this, but is still less extreme as the potential speeds are typically much lower (ranging between orbital velocity at LEO and escape velocity, and they are going that fast in the upper atmosphere, rather than the far denser lower troposphere), you'd see that most of them work by ablation, where basically they are designed so that, as they get heated, the outer layers fall apart and carry away some of that heat. That's because only a few extremely specialized materials can actually survive that type of condition. The space shuttles didn't use an ablative shield, but you can see what happens to something without a very specialized shield if you look up the Columbia disaster, where the heat shield was damaged during launch which caused the shuttle to disintegrate during reentry. A hunk of steel that is not remotely aerodynamically stable would not survive conditions even more extreme than that for more than a few meters, it would be torn apart by the extreme forces while also being vaporized by the heat generated from the collision with the air. Yes it could be argued to be the fastest man-made object, but when you're only going a matter of meters due to not being able to survive those conditions, that's not meaning it made it into space.

      I think he was expressing that the crashes weren't pleasant, not that they felt actively dangerous or were injuring him.
      After the producer from the infamous incident where Adam got shocked by a cattle prod basically, the mythbusters had a lot of control over the risk they personally took. And it seems like they are often being prevented from taking risks by the production team (more often by their insurance lol), rather than being pressured into it. I'm glad they recognized that even a relatively low speed crash could potentially hurt him and had him wearing a proper helmet though. Looking at his head flop around, I think getting whiplash would be a pretty real danger had he not been wearing that

    They didn't put any shock tags on buster to ensure that the sound wave from the blast in effect him by having the bedliner on it.

    If that was six mph, I'm the Pope. It was at least 15 mph.
    Also, @19:50 Grant says "we're going to build a dog-biting robot. No, you're not. That would be a robot that bites dogs. What you're going to build is a "robot", if you can call it that, dog head that bites.

    Historically there are examples of manhole covers flying into the air due to an explosion transmitting into the sewer. The East Ohio Gas explosion is one example.

    Guadalajara, April 22nd, 1992. A series of explosions destroyed 8 kilometers of street killing 252+ people. The cause was a gas buildup in the sewer system starting on the 19th.

      The nuked manhole cover actually exceeded the escape velocity of our solar system. It’s now the furthest man-made object.

    Exploding Manhole is Confirmed big time steam, junk, closed sewer, or a blocked trash rack it can blow up the sewer and launch manholes. Another reason this is confirmed it happened in San Francisco during the quake, it happened in New York when there was a blockage at the Con Edison Steam Plant, it happened in Mexico, and a big one tore through Rio after the sewer got backed up it can happen.

    Manhole covers are round because the holes underneath them are round.
