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.
I once accidentally drove into the base of a concrete light pole at 5 or 6 mph and I had never been so thankful that dashboards were made of plastic in my life.
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.
The American Govt got Kentucky beat by like 2 to 3 years after the people wanted them to stop underwater nuclear test they set a nuclear war head about 400ft in the ground with a explosive just large enough to set the warhead off and it launched the manhole cover at like 123,000 mp/h it was only on camera for a frame
i never in my life woulda pegged grant as the first one to leave this world and thought its been a bit and i just saw the dude ont tv its one of them things that has stuck with me
I like to think he was working on something really important and using his genius brain he was thinking too hard which caused the aneurysm. He was too smart for this world :(
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.
@@auroraourania7161 I've clearly been watching too many comic book videos recently, because after the initial 'that's sad' I read 'testing a rocket car,' recalled 'maternity leave,' and thought, 'that's a superhero backstory.' RIP Jessie, I hope your kid's doing well.
I wish that they could check two more things 1. Actually check what would happen to Buster sitting on a toilet conected to closed system sever 2. Paint the bottom of a car with that red stuff and check it for landmines
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.
Makes me wonder how effective that bed liner would be against medieval weapons, if you layer/articulate it like steel plate you should still be fairly mobile.
New sewer explosion video came out about a month ago from china. Blew every one in a city of like 40k people. One video of it shows the right lane of light traffic, at the fogline they are just getting rocked for like a mile, over 20. Some covers took most of the lane with them. Guy drives past them all after in the same vid.
Hold on they are trying to make the car "crash proof"? Why is no one mentioning that *removing the crumple zones by reinforcing them* is a sure-fire way to DIE?
I never understood why in some tests like the manhole one they did not have an extreme wide shot to be able to see the full height these thing got to, was it missing foresight or maybe they lost the footage as it happened sometimes 🤔
It wouldn't surprise me if they had it, but the resolution wasn't good enough to actually be able to see them in the wide shot so they didn't include it in the cut
The fastest man-made object in history was actually a “manhole”cover used during the Plumbob experiment in the Nevada desert. look it up!!!! It’s pretty cool and estimated 150,000 miles an hour.
TH-camr Kyle Hill just posted a video about this experiment where he posits that the cover was annihilated rather than launched up. He brings good evidence for that hypothesis. I don’t think we will ever know.
@@RangerMcFriendly it was launched specifically due to the expanding gases, so the heat wouldn’t have reached it in time to vaporize it before the gas propelled it upward, so it wasn’t annihilated from the explosion itself, and because of its speed, it was not able to gather up enough heat while going through the atmosphere to be destroyed. That way only logical conclusion is that it is still traveling through space
30,000 years from now a manhole cover screams into an alien atmosphere and hits a building killing a family of 4. The War of the Worlds begins and the Emperor of Man makes his presence known to combat the alien menace.
@@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.
All of the cast pours it on for the entertainment factor. As well as to dissuade the audience from mimicking their experiments. They'll all often feign surprise or fear. When someone with a background in engineering or other applied sciences. Would have a fairly clear idea of the outcome.
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
IIRC thats due to not wanting any potential outsiders influencing the dog with commands besides the handler. If you're on the run, you're not going to try see if the dog responds to french or german or whatever.
a friend of mine used bed liner to line the interior flooring of his convertible classic car which actually turned out great and helped him to not have to worry about it getting rained on plus added strength to the body.
I've gotten kinda old, is that a Ford Tempo or Escort? I'm thinking Escort. Either way, wooww 😮😮😮 , I haven't seen one of either of them in such a long time. It sucks how easy it is to forget things.
They should have done two more explosion on the bedliner and coated only the outside surface and only on the inside surface see what the results would have been.
When I was 8 years old I saw a sewer explosion it sent the storm sewer grates high in the air and also shot two children out of the discharge pipe into the dry creek bed. They both lived but where badly burned one spent 6 months in the hospital the other a year.
Back in 2005, the city of Mt. Clemens, MI had an incident where utility workers accidentally set off the gases in the sewer. It did indeed blow manhole covers into the sky, damaging vehicles, buildings, and people. Source: I was standing outside the Emerald Theater waiting to get into a concert when it happened. Shit was wild. Band canceled and bailed because, at the time, people were still pretty nervous about terrorism.
Police and rescue dogs are usually trained in Germany or The Netherlands. There are a couple companies based there that are considered the best in the world. It also helps to train the dogs in a language not commonly spoken in the country they're intended to be working in, to avoid confusing the dog with potential accidental counter commands.
Before vented covers it was so common the fire dept had written rule no parking on manholes.When I was a new guy we were still riding on the back.Then there was an explosion. The old guys I was with, had a heads or tails bet before it landed.
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.
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.
I guess its a good thing Jamie could not build an atom bomb and get permission to fire it off in the desert or they could have done the ultimate manhole explosion experiment. ;)
