Unironically, one of the best things of my year has been the uploads of Mythbusters to KZfaq ❤️

Loved Adam's reaction to Jamie's geese joke. 😀 "Was that a joke?! I think that was a joke! [pause] Fascinating!"

What a glorious alternate future we missed out on where cars could suffer catastrophic magazine detonations

24:53 Probably another instance of the infamous producer instigating bad behavior for "better television", like the electric shock Adam got from the golden statue.

I have been waiting for this episode... I can't wait for the 22,000 feet drop episode. That is the one I am most excited for.

20:49 Adam's laughter there :))))))

Air Cylinder Rocket and the Blackpowder Motor are two Classic, nice Episode.

20:54 that's agent walrus's favorite phrase "It was the lard that did it" /:€

The thing about lawnmower engines is that the grass cutting blades act as the flywheel. The flywheel keeps the engine rotating between ignitions as well as smoothing out the action of the engine. If you take those blades off, you have less to work with than if you used an internal combustion engine from any other application.

25:09 u can see that Grant was legit mad. He had his fists closed for a second, but he remembered he was on camera hahaa

instead of the valves into the water they could have had the air pressure firing at a paddle wheel pushing them forward

Tori’s engine looks wheely good

They should have added a diverging nozzle to the air cylinders in the first configuration, would have given way more thrust

“Can you feel that?the vaccume is pulling me in” *”Yep,it sure does suck” 😂

25:20 As someone with chronic tinnitus, I know that pranks like that are not OK! It can really ruin someone's quality of life! Hearing protection should be taken seriously. Same thing with air horns and whatnot.

Carastrophic failures proven right is easily my favorite brand of MB

It's nonsense that black powder has higher energy density than gasoline. Most people think explosives have higher energy density which is rarely true. It just combusts a lot quicker.

My favourites are the episodes with the hot water heater explosions. I can watch those episodes over and over again and still feel happiness every time!

Isn't an automatic rifle a black powder engine with a high velocity exhaust pipe?

I think if you'd have gotten the boat on plane before rocketing off, it might have worked better. As we know, water surface friction at low speed is a pain, and speed gets easier once you get past that.

29:07 holy shit that joke was dark 😅

I was sweating just seeing Adam on a leather jacket in a beautiful sunny day!😅

R.i.p grant.

16:00 Engineers at the time had this obsession with a vacuum. The first steam engines also worked on that principle even though high pressure has far more power and doesn't require nearly as good seals.

DAMNIT my gunpowder pump and injector are clogged again xD

20:00 "Calm, steady words from a man who's hoping to launch a gas cylinder into the next county." Welp, that didn't really age well in hindsight...

Legendary Episode

A few years ago, Richard Hammond did a documentary, "Gunpowder plot, exploding the legend", to see if the explosion would have worked. it was really good, worth a watch. Anyway, I always thought it was in MythBusters wheelhouse, and I cant help wondering how it would have gone if MythBusters had been involved.

Not quite like in Gary's Mod, but similar :)

Man i miss this show. Loved this as a teenager

To put the air outlet under water; good idea. To put the air output level with the boat; bad idea. To get some distance/speed you want the boat to stay level with the water instead of the front to come up, the rear will become a big break. Put the air outlet pointing slightly down or use an extra rudder to keep the boat level.

Adam, out of bed and into the studio :D

3:00 forget the building... That doesn't help... You want to be a minimum of 10 km away from it.

I recall when Jamie got that black eye, from the hand winch experiment in the superhero episode. I remember wincing!

Grant: “don’t say anything” as he’s wearing an embarrassing suit. Editors: puts it in the intro so it’s part of every episode.

I have such a competence-kink. Could watch them actually design and plan and build something all day!

I take it they have never played with an office chair and a CO2 fire extinguisher?

Funny. In Spain we can lay the blocks the other way up for a fast light wall, cavity up for filled blocks. Heavy wall.

Wonder if this episode was done before the release of 007 Die Another Day, coz that was what Pierce Brosnan did in the lab in Cuba chasing Jinx.

With high pressure cylinders like oxygen tanks the stories of them flying through two walls and being found several hundred yards away are usually when they've been involved in a fire. Imagine a 3000psi oxygen cylinder thats been slowly brewing in workshop fire thats now overpressured to maybe 5-6K psi when something falls on on it inside the burning building - really conceivable they could get some serious air time. The incident i remember as kid was a fire in a mechanics workshop - an oxygen bottle flew through the cinderblock wall into the joinery shop next door (leading to burning the joinery shop out to), out the wall of the joinery shop, over a small river into the bottom of someones garden. Total distance maybe 150-200 yards?

"a grain which is 1 /500th of a (*Troy) ounce..." which should NOT to be confused with the ""standard"" Ounce in which case a grain only is approximately 1/437th of an "ounce". Or to put it another way a grain is approximately 1/27th och a Drachm (*dram), which in turn is about 1/16th of an "ounce", which is 1/16th of a Pound, which OF COURSE is 1/14th of a Stone. Ziimples... It's so good to have a """system""" ;)

Since the key to the thermodynamic cycles of combustion engines is the "adiabatic process" (no heat and particle transfer); the lack of latent heat (phase transition) prevents gunpowder engines to complete a full cycle. Steam engines on the other hand, use an expanding medium (steam) to create an enthalpy change in order to keep the reaction going.

also love how they enabled the comments so we get to talk about the show

Numerous other mentions of gunpowder engines, but it does not appear any were used operationally.

Maybe if the block wall done properly, with virtual rio bar and concrete poured within the blocks to core fill them… 🤷‍♂️

27:07 Tori getting a little sniff of Kari’s hair?

Black powder (and any other explosive) has less energy denisty (1-5 MJ/kg) than gasoline or other fuels (30-40 MJ/kg)

WOW GRANT WAS ANGRY IMMEDIATELY

32:48 I think I don't understand this argument, Adam got overexcited with the design but it was in the spirit of Mythbusters.

kislux versace bag is so cute

Have you tried to use the Gas tanks as actual water torpedoes? Strap a pointy edge on it and you have a pretty useful improvised Anti Ship Weapon

Now do this with 200 bar (2900 PSI) Hydrogen. Harharhar ...

44:20 Scuba instructor joke

The wife of a friend of mine was killed by a fire extinguisher which fell over, flew across the workshop, and hit her in the head.

just a cylinder falling on the floor can cause it to go in a straight line it happen where my uncle worked

You always have to lube the shaft so you can release the gas 😂

The tank shit happened to a guys dad. He had a tank in his car with the valve directed to the dash. The valve blew, the valve went thru the car and his Dad celebrated brithday twice a year from then on. Don´t mess with gas tanks, kids

TBF they use these to steer Falcon9 rockets, so they aren't useless.

It's weird watching these knowing that Grant's dead.

1:42 Which episode is that?

The Gunpowder inside the engine MIGHT work if you use it mixed with Gasoline, OR Gaseous Fuel (GLP) or something. I WANT A RERUN!!

I feel like the black powder "joke" wasn't Tory's idea...

upscaling would be nice

Why not use Black powder pellets? each cycle drops a pellet rather than a measure of powder?

i must be Dislexic again i readed Cinder Rocket!!

5:50 Mass Effect 2 Loading screen music!

I think the gunpowder engine would work but you would need a gatling gun or sub machine gun foreign blanks into the chamber which is not very cost effective

Should´ve used real bricks instead.

Something happened to Jamies eye… Anybody know what? Interesting they didn’t cover it in makeup

19:42 I wonder how Jamie got that black eye?

under the water

Thats not a core filled wall though

RIP François Gissy 🚀

The boat didnt go fast enough because the air is not good to push boats

It's a TV show!

any ideas as to why Jamie has a bruised eye?

R.I.P. Grant, you'll be sorely missed.............

So i'll run my carburated engine on black powder for extra power

Oh its a new video i think i watch old one

I think if they can some howlower the noose of the tanks under water the thrust will be me much higher since it pushing again water not air

Can u not make a liquid from black powder then ignite it ....

1 grain=1/500th of an ounce==??? Grams

eh was not 2 stroke invented back in their time

Why not stop with the telling of the myths and start putting them to the test … wait a second!

I love how Tori is just a walking intrusive thought.

ah man, @25:10 was brilliant! Tori's expression was golden, he didnt expect that reaction....neither did I. Grant was like, what did you do? looool

I wonder why they re-edited this episode in such a weird way? You can tell even from watching this video but the whole episode was shown in another order back in the day.

According to Wikipedia data table Gasoline specific energy is 13.3 MJ/kg, nitroglycerin and ANFO are about 6.5 MJ/kg and TNT is “only” 4.6 MJ/kg. Hands down gasoline beat the sh*t out of all high explosives in terms of specific energy per unit weight. Your experiment is flawed because you didn’t measure the quantities and didn’t ensure the stoichiometry of the reaction for gasoline, chemistry please. Grant (RIP), getting rid of fossil fuels with an engine that runs on ….charcoal?🤦‍♂️😂 Really a disastrous physics lesson, at 28:10 you add up 2 2600 psi cylinders to get 5200 psi. 😱🤷🏻‍♂️🤌🏻 Hellooooo, pressures don’t add up, they equalise, volumes will add up. Back to hi school everyone!

im not so sold on the busted black powder engine. i dont think they really went far enough to iron out the problems. we have automatic rifles which reload themselves. they can be considered black powder engines.

LOL

Haha! 07:09 They showcase those fragile, brittle, hollow concrete "bricks". I've even seen the modern rogue, Brian Burshwood break those cinder blocks over his head as a part of a magic act. Apparently they are not sturdy at all. Anyways, then the narrator says something like "let's see if the power of this 2600 psi air cylinder-thing can shatter a solid brick wall"... "Solid" "brick" wall.. Built from fragile, brittle, and more importantly: hollow... "bricks".... "Solid" brick wall... Hollow "bricks".. "Solid" brick wall... Hollow "bricks"... You can probably toss a hammer through that "solid" "brick" wall. I wouldn't be surprised if a glued duplo-lego wall of that size would be sturdier. The definition of solid is better used in describing the 40 pound solid steal bar. That's what solid means. Not fragile, brittle, and hollow cinder blocks.

If they wanted to test that old drawing of a black powder engine, a single cylinder 4 stroke engine would've been perfect. One would have to remove 2 valves, attach the cable through the spark plug whole, and weld a cap at the bottom of the cylinder. The piston is already designed to do a pretty good gas seal. To remove mass, material could be milled out from the bottom section of the piston (anything at and/or bellow the wrist pin boss).

14:02 nice

How stup*d is it to build a fragile wall a few feet from the actual building?

I'm the first one here 🥳

Why does Adam always laugh so hard , loud and fake?
