- Can a manhole cover be propelled upwards by a methane explosion in a sewer without the cover being destroyed?
Using science as a tool, Hollywood special effects experts attempt to debunk rumours, urban legends and popular myths that have captivated the minds of many individuals.

I think as we've all learned from the cybertruck... you dont actually want a car to be indestructible and crumple zones exist for a reason
Cybertruck has crumple zones and is safe.... for the people inside it. People on the outside though are all dead as they get hit by the stainless steel knife.
Oh don't worry. The Tesla engineers thought of that too, and designed it so it rapidly disassembles itself within a week of use!
The crumple zone is the other car
cybertruck has a better crumble zone than the F150
Can you just shut the fuck up? Tesla has been widely regarded for making extremely safe vehicles (go look at their crash tests).
We don't have any data yet on the CT because the NHTSA hasn't released it but there is no reason to believe Tesla didn't also set out to make the CT just as safe as any other vehicle of theirs.
You're a moron and dullard.
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
but yet cant stop people hacking the computer system
@@ozzykrahn806 It could if they used an axe i guess
@@martinvaldhans3679 - Concete is bad in dealing with tensile forces. The liner helps.
Mythbusters IS a cultural moment, Grant
31:04 "does Cliff like italian?" "he's never had any"
iconic
the cop is so devoid of personality. You're on TV for god's sake, you don't have to seem like a lifeless dolt
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 :(
Man, I love this show. They did a really good job when making these episodes back in the day. Always entertaining and informative 👍
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
landmines?
@@calumsanderson6741 boom boom boxes that bad people can leave on a road to make cars and tanks go boom.
@@calumsanderson6741 There are still parts of Europe that have landmines from WW2
I'd like to know your first one and then how big of an explosion bedliner can hold up against
Απίθανο επεισόδιο όπως όλα !,!
Mythbusters truly is the greatest show ever made.
They should have tested with blast discs… we all miss you all
R.I.P. Grant
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 be rack up costs in repairs so that you don't have to pay it in the hospital.
24:37 - Finally! Someone shows us! You load 16 tons, you get a sewer explosion!
Alr this is a hilariously underrated comment.
Wonder what wouldve happened if they used Number 9 Coal 😂
@@EmilyChuu OOOOOHHHHHHH! We must reunite the Hyneman and Savage to see if they would do it!
Now I realized what you get from 16 tonnes.. 😅
Did anybody else catch that the commands for Cliff are actually German?
It's a German Sheppard bro
If you watch US police stuff most of the dogs get german commands
It's a German shepherd after all
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.
@@goldenpggie9788 well, you will notice if German or French is (one of) your native language(s)
The sewer explosion is my favorite of the whole series. Just amazing.
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.
Saw this too!
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.
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.
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 🤔
I mean, their estimates were at around 20ft so they didn't think it'd go this far
I would love to see these without the duplicated information from the commercial breaks.
Herborn/Germany .... 1987
It RAINED manhole covers for 20 minutes in the whole town.
I was there ....
absolute cap
I was the manhole cover, can confirm, that happened
I have a manhole, but that might not be what y’all are talking about…
Seeing Grant clearly very uncomfortable with the force of the crashes, but apparently being told to continue them makes me feel a certain type of way.
Seems he was hamming it up for the show
36'45" - Adam - "I'm going to start the flow of gas." Jamie - "Let 'er rip." 🤣😂🤣
Gee i love season 8 episodes, those are the best after 4
the body work will still be damaged just u cant see if becuase of the liner
Thanks! I really enjoyed this one.
Exploding manholes is what happens after you and the guys have a night out at the local mexican joint.
I would love to have a car with that coating! Aside from the obvious scratch resistance it looks so cool 😎
Oh full episodes are back.
Weather proofing with bed liner
The fact that the german shepherd has to be issued german commands is so hilarious
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.
It’s been a widely known fact for YEARS that police dogs are trained in German… literally been that way for decades, maybe longer.
If only they'd had camera drones back then!
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.
Uh.... bedliner could protect tank crews from spallation...
40:20 toilet fireball 😂
I miss these people 😢
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.
Perhaps bedliner should be sold as Hurricane protection?
This is the first time i heard them with their original voice, they didn't sound nothing like i expected 😭😭😭😭😭
Wonder if Grant got the aneurysm from the head smash during the car accident in this episode. He seemed pretty rattled.
Not funny
Probably the bedliner can be used to stop zombie bites 😂
Supposedly one of the fastest things to ever be launched into outer space was a manhole cover.
My autism thanks you here goes 6 months at least
They didn't test bed liner against deep sea implosions.
Is anyone else worried about the dog's teeth after biting the bedliner?
Bed liner: high wind (hurricane or tornado) proof?
Wasn't this episode already uploaded a few months ago?
"All in all, it's just another brick in the wall." Love it!
World's Biggest Pipe Bomb
A manhole cover potentially was launched into space during a nuclear test, though.
(It had the velocity, but it's lack of heat shielding is the questionable issue)
Anyone else thinking of the Linex watermelon on How Ridiculous?
ahahah I didn't know american police trains their dogs with german command words. "fass!" (bite) "aus!" (off, finish -> stop), "platz!" (place -> sit)
I don't know about sewer manhole covers but a nuke can yeat a 1-ton manhole cover into outer space!
The nuked manhole cover actually exceeded the escape velocity of our solar system. It’s now the furthest man-made object.
Are we gonna talk about the fact that they basically made a pipe bomb when they closed the system and added a bunch of shrapnel in it?😂 16:03
The only difference is that the pipe bomb has more gas pressure which over comes the pipe and makes it explode😐🙃
Watching grant run into that concrete barrier has got me wondering if that could have possible contributed to his aneurysm
i want to see what would happen to a car that got hit by that sewer grate as it blew sky high. i want to see how far it would launch the car as well lol.
This happens in china all the time there was one not too long ago where the manhole covers on the free way exploded thay went super high up u guys should see it eas pretty crazy
Operation plumbbob.
But in the long term wouldn't you be breathing in particulate of the bed liner if it is protecting your home? I'm wondering if it is carcinogenic.
Its made of a polyurethane mix which can cause allergic reactions but as far as I know is not carcinogenic. We're not looking at a new asbestos or anything. I'm not sure there would be much particulate, as when cured its basically a plastic. I don't think anyone should actually go out there and spray it on but it also shouldn't like, kill you. Another commenter mentioned they use a similar coating in the pentagon so at the very least its safe enough for the US' military officers.
the math is wrong in this one. german sheperds only produce 291 lbs of force.
This kind of Methana blew up the main street In gauteng CBD in South Africa. It flipped cars over and killing people. Footage on youtube.
Jamie is wrong with his gun example, recoilless rifles aren't actually a closed system and they vent gas out the back and yet their projectile still fires. Thats how theyre "recoilless" by equalling out the recoil from the projectile with the force from the gas venting backwards.
Thats because recoilless rifles are not guns, they are just a way to aim a rocket. Hence, "Rocket Launcher"
@@dreadnaught688Recoiles rifles and rocket launchers are two different weapons. Rocket launchers like an RPG7 use a rocket or series of rockets to excelarate their projectiles.
Rechoiless rifled like the Carl gustav are indeed oversized guns which use gunpowder to fire large projectiles. By very carefully sizing holes in the rear of the casting and the rifle itself they vent an amount of gas backwards equal to the force of the projectile coming out the other end. For this reason they commonly use more than double the amount of gunpowder necessary to fire a round.
Well drat... the SueAge we live in wont allow them to destroy an actual sewage. Tsk. :p
34:48 works for turtles
@31:34 did he say "fass"? it sound like the german command for the dog.
@31:55 "aus, platz" yes. they are german words
Well yeah, it's a German Sheppard what did you expect
Haha! Yeah, but I'd GUESS the idea being using other languages so people talking won't confuse the dog.
@@Savahax Hmm, right. ^^
so commands to the dog are direct and not mistaken for commands to someone else or every day speech
"Fass" = get it (coming from etwas fassen or anfassen - to touch something)
"Aus" = Stop it
"Platz" = sit down (from get onto your place (Platz))
19:33 I missed out on this. What is this referring to?
Grant is referencing a line from Hamlet written by William Shakespeare. Hope this helps!
10:36 foreshadowing 😅
Well as we recently found out, explosions underground can send a manhole cover into literal space
Of course the irl actual incident included nuclear explosion testing underground and not accounting for air pressure, sending said cover straight past escape velocity
Yes. I have seen one.
The only time I saw it (let's say I was watching the event, but since it happened under the race car I never saw it,) the race was stopped while crews went out onto the track and rewelded down just the failed cover before resuming the race. My memory seems to think the race was in Canada maybe even in Quebec but that is just basically a random thought at this point since the race was ages ago. Sorry I get that this is kind of off-topic, but a manhole cover is a heavy chunk of steel.
Dog was HORRIBLY trained, took the cop like 5 calls at least to stop him.
Can the german shepard only speak german?
Yeah was kinda surprised to hear that. Maybe the dog was originally trained in German so it was easier to keep using the German commands he had already gotten used to?
Also French
Happy SnowFurfee i hope everyone is having a beauitful EarthRise..&.EarthSet i hope you ALL get more likes comments subscribers
🥶StayFurfee🥶
There is an issue with the link to your channel !! I can't open the channel to see the other videos. ruclips.net/user/MythBusters does not work.
And www.youtube.com/@Mythbusterstvshow redirects you to the other one, which does not work.
It has been like that for me for the past view days. Sometimes it works, sometimes it doesn't. Almost like RUclips can't figure out if those Episodes are legal or not...
The @ link is just because YT wants us to use new names, but they're both the name of the channel, just like mine is Games_and_Music, while my channel really is called DethstruXioN™.
It's stupid anyway, because in the chats they still show the old name, but here in the comments they show the new one, it has never made any sense.
But yeah, i'm not sure what is going on with the link here.
It does work if i click on it directly, but i get the "404" when i want to open the link in a new window/tab.
It has also been messing with the adblocker even more as well, might be related, but i don't know.
@@Games_and_Music yours does not have this issue
@@nikroth Fair point, i just checked with a video of mine and clicking the channel link and there was no issue indeed.
I had noticed that glitch before a couple of days ago, but thought it was just a random short glitch and instead opened the channel in the same tab and opened new tabs to watch episodes in.
But i hadn't binged in the week so i hadn't run into that glitch again, but it's apparently still there, weird indeed.
Garbage?
Please add English subtitles for foreigners like me.
Do a show on hollywood hacking of lifts, cameras and other stuff. Let me know if you need help on same 😊
The fact that you can’t tell the show is old and that you think they would consult you is actually impressive
@@iLaCorelol, i guess if they do a youtube version of it in coming future they may 😂
Lol
FIRST
No views in 1 min, channel fell off
I got into Discovery Channel as a kid for this show and How it's Made.
Be happy this bullS....t is over
11:51 Look how hard his head, neck, and body are jarred here. I wouldn't be surprised if this had something to do with his premature death.
A 55 gal barrel will also stop a dog bite get in
There is an issue with the links to your channel ! /MythBusters does not work. /@Mythbusterstvshow redirects you to the other one which does not work.
same happens for me. in most places clicking on the channel link on the desktop site leads nowhere. i wonder if RUclips messed up some channels when they transitioned to @usernames not long ago
My autism thanks you here goes 6 months at least
