Shooting Anvils with Gunpowder | in Super Slow Motion! 

Thanks for Henri for helping with the gunpowder and ignition! Check out Henri's new channel Pommijätkät ru-vid.com/show-UCr1cNqiNxK46w93zw9KfTLg Videos are in Finnish but I try to make Henri add subtitles to videos :D

When I was a kid, the cartoons all had anvils randomly falling out of the sky. Today I learned they actually came from Finland!

In rural areas especially poorer ones, it was a common way to signal for help. It is called " ringing the anvil and usually is accomplished using a pound of black powder for an anvil . Apparently a single pound of gunpowder was cheaper than buying a town bell.

Love the camera around the ladies neck. Looks like a 35mm film SLR !

The mixture of accents is great

I believe slower burning powder combined with a much better seal will give you better results. Slower powder pushes heavy projectiles better which is why it is used in higher caliber cartridges.

I love the safety glasses......just in case an anvil lands on their heads from 50m in the air. 😃

Anvil rocketry! Fantastic!

Put peanut butter or grease between the anvil surfaces around the powder chamber as a sealant. Seal the two anvils together with glue around the powder chambers

Greetings from the international space station!

Excellent! I've been looking forward to this ever since you mentioned it. The finnish space program was a good surprise. So you're working on reducing spacemen to the particle level now and working on transmitting them across distance later and reconstitution even later?

You might want to go with solid rocket design. Generally, with solid rockets, wider rockets give longer burn, while longer rockets give higher pressure. So I would suggest that you try a deeper and circular hole. Do fill it, but keep a hole through the center of the grain (powder fill. And put the initiator charge in the bottom of the hole. This will allow optimal pressure build up. Of course you could then put a throat to chocke the flow and get higher pressure. But that's making a solid rocket out of an anvil and nobody in its right mind would do that, right?

I think you need to slow down the explosion with slower explosive so the explosion pressure has time to work on the anvil. The explosion power is used up before pushing the anvil up. Sincerely just a guess. Good luck

Make the hole in the anvil deeper or bigger to allow more expansion of gasses

I thought was to use a tube shape in the bottom anvil so the blast would have more pushing force in a smaller surface area.

You have to epoxy the two anvils together. Epoxy has incredible holding strength when bonding two machined steel surfaces. Allows for incredible pressure to build before the epoxy fails and launches the anvil.

Interesting, I've just watched Big Clive's latest video and he mentions the origins of firing anvils with gunpowder. Apparently it was the Blacksmith's way of proving who had the best quality powder...

"Finnish Space Program" made me LOL!

The contact surfare between the anvils should be very smooth and precise, an air tight seal almost! No paper inbetween! Also, no need for a cavity on both anvils.

Shaped charge but reverse of the usual? You want a flat wavefront hitting the bottom of the anvil - so shallow in the middle and deep around the edges?

Regardless of power shot. That soft ground is absorbing quite a bit.

Jeah, but thats sheating 😂😂😂😂😂👌

make the hole of the upper anvil a little bit deeper and fill the hole of the lower anvil with a metal plate that sticks out a litte bit. So the explosion gas cannot escape to the side so easily and the anvil will fly much higher...

I suddenly want to move to Finland.

OK, that was interesting..... Who first got the bright idea to do this with two anvils? Must be a trending RU-vid thing!

Glue them together with super glue. It will allow the pressure to build for longer.

I have a feeling that a blast shield wont help a lot when a 50kg anvil flies towards you.

I think they should put C4 in each anvil and the blasting cap in between them.

If Bill and Ben where allowed explosives... #FlowerPotMen 😂

Damn. If you were to somehow be able to direct and aim that some real damage could be done. Wow.

You guys are crazy! how about putting explosive inside each anvil cavity to see if the double explosion gets 100m?

You need to use peanut butter in between the 2 anvils

imagine u were a bird chillin at the crib and these guys are blowing shit up in the backyard

10:18 Finnish Space Program hahaha

Finnish army scientists trying to recreate german V2 rocket to annoy soviets (1944 colorized)

Same Hole, Only Deeper Each Time :D lol... The Only Way To Do It ,Right :).

you did not show how you detonated the powder. what did you use? (ebw, slapper, shock tube...?) what was the grade of black powder? was it powder? what was the "super"? why dont you try some C4 or tatp?

It's a pity that the original crew left MythBusters... Other wise, you could contact them how to make something disappear with explosive material... They have some experience with that.... I remember an episode of them where they tried to clean a cement truck with explosives. That didn't work out as they hoped for.... But they were stuck with that old cement truck... So, they placed a shitload of explosive stuff underneath the truck, and blew the damn truck in to smithereens...

I was searching RU-vid for videos of this just an hour ago, how strange.

He's gone home to do science stuff

jb weld them together lol those who do this as a sport use peanutbutter for a better seal.

Finnish Space Program !

I love this shit!

build the worlds biggest mech mod vape

Finnish Artillery is crude but highly amusing

12:00 Lauri: I only can throw the anvil with my bare hands about 10m so it was way more-- Anni: eh, what?

“Same hole, deeper every time.” That’s what she said.

You should have used creamy peanut butter to make a temporary seal between the anvils. It will increase the pressure between the anvils just long enough to get serious pressure and height.

"It's good to try things careful" says the guy launching anvils in the air with gunpowder.

The next step is to turn the anvil into a type of sabot round and shoot it from a tube.

!!!!!❕❗‼❕❗ at 9:00 minutes the red band can be seen in the tree. just behind / above the flap of the car.

That’s some heavy firepower..... REEEEEE

Big Clive was just talking about blacksmiths testing black powder by blasting anvils in the air

sounds like an extremely safe idea.

Scott and Cy were using 1 pound (454 grams) of powder to shoot their anvil, which looked to be about the same size as yours. the result was a bit better but similar to your efforts. Stay safe!

Same hole, deeper every time..... Lauri always on point with the jokes. :D also I finally received my Turkisk Peber I ordered and its great! It's not very spicy though :D must be I'm used to really hot food.

Ok, this does it, I'm applying for Finnish citizenship … ;)

"finnish space program" is as efficient as SpaceX: comes back landing on feet first, is re-usable and is fun to watch one step nearer o mars - you should patent this ;)

New potential band name: "Finnish Anvil Farm"

Hahahah, this is brilliant!!! :D You have taken backyard mayhem to a new level with this one! I really hope I'll get to meet you some day!

I like the Finnish insertions for example countdown at 3:48 It's so different from Swedish or Norwegian :) Also great video! :D I really enjoyed.

0:27 "Do or do not. There is no try."

I love Lauri’s strong intuitive sense for how stuff works, and how to optimize for best results.

Glad to see that you were/are taking the safety seriously! A neighbor of mine killed himself doing this. He did several things wrong--old cast iron anvils, too much powder, no safety equipment, and he was not nearly far enough away--and the anvils shattered, sending shrapnel flying in all directions. A small chunk of one of them pierced his chest and that was it for him. He'd launched the anvils about 8 or 9 times prior to the last blast. Very cool to watch, though!

"We are not cheaters in Finland" "And we are professionals cuz we get paid for this"

Lauri's a genius, but his word choice in English is hilarious "I've got to do some science stuff" doesn't inspire confidence if you don't know lauri very well. I'm eager to see what you "science" to break that record!

"Stunt person smoke, don't breathe that" lol

Finns are pretty much the coolest people on Earth. Everyone else needs to catch up.

I love finland and finnish people, Mina olen jaakapissa. Yes i am.

“Don’t try anything like this, it’s really stupid!”

Try drilling a really deep hole in the blue anvil and make a piston, you need to contain the pressure long enough for the red anvil to have time to accelerate. The way it is now your just dumping all the pressure as soon as there is enough to move the red anvil.

same hole,,but deeper every time!-THAT's what SHE said,,,,,LOL

10:55 was really funny, made my day

Lauri "it costs 200 euro if it breaks and you pay" And almost before Lauri could finnish (no pun intended) the sentence Henri´s like "okej, sounds good, let´s do it!" No hesitation there XD Lovely!

Kim Jong Un has liked your video. He asked me to ask you if you'd like to be his new Secretary of Defense. You have to get a North Korean approved haircut though... I think there's like 28 of them...

Would it be possible to direct the explosion gases through some thin hole to use it as an explosion cutter?

I love how much you enjoy these experiments. I also enjoy this very much as do most of the viewers. Fun based on expertise and planning. Brilliant.

Man, I just love you guys. Thanks for great entertainment.

Finer powder = more surface area = faster burn, up to a point. Large gains = less area = slower burn...until the grains get smaller and burn faster! The 'ideal' situation sees the anvils starting to move apart just as the pressure is reaching maximum. Black powder muskets have to be 'tuned' to the powder they are burning for this very reason. An 'ideal' burn with muskets is to have bore pressure still climbing just as the bullet is leaving the muzzle. Accelerate that bullet all the way down the tube. If the pressure spikes too soon, the bullet will be slowing down in the barrel after the pressure spike has dissipated. If the pressure spikes to late, the bullet doesn't pick up much speed and most of the powder is wasted out the muzzle. Loose black powder, in a confined space, tends to explode rather than burn; every muzzle-loading gun requires firm compression of the powder charge to prevent barrel explosions. I am guessing that a medium-coarse 'cannon powder' would be groovy, but you would need to find a safe way to compress the powder charge into the anvil recess. Not super compressed, but enough to close the bigger gaps between the powder grains. The flame front moving through the charge should burn through the grains, and not around them! BTW, smokeless powders would be of no help here, they require massive [20+ bars] pressures to burn fast enough. Hmmm, fast black-powder to build pressure/heat fast, slower smokeless powder to maintain/build the pressure spike...hybrid charges may not be according to Hoyle...space program...

🗣HILARIOUS ‼️😂😂😂😂 Finland we have a problem launch vehicle has returned to the pad.

Are you using NC or black powder? If NC, I strongly hope, it's Vihtavuori ;-)

All the people that do this competitively use something sticky between the anvils to keep them together just a bit longer, this increases the internal pressures and launches it much higher.

When ISIS tries to invade finland and don't add the HPC into the calculation.

Your channels are the greatest thing I've discovered on youtube in a long time. So much fun and so satisfying to watch. Please keep them coming forever. I always wondered what I'd do if I had access to a machine shop and now I know.

"This is the new way to remove paint, gunpowder blast. It’s a bit like sand blasting, but better" Ya, definitely on the entertainment value as well ;p

"Finns are not cheaters" - love that!!! Americans just put more gunpowder...

I saw a video with a champion anvil shooter and he used a notepad trimmed to the exact shape as a sort of head gasket between the anvils and his went very heigh.

I didn't see anyone raking the forest in the background. You guys are gonna start a forest fire ;)

Hey, you scratched my anvil.

You make some of the craziest yet interesting videos I've ever seen.

“Don’t try anything like this because it is really stupid.” 😂

My god Finland looks like a blast - pun intended!

7:50 "Same hole, but deeper every time" 🙊🤣🤣🤣

OK, it's crazy! It's nuts! But it is very entertaining. so thank you and thumbs up.

"Same Hole Deeper Every Time" Thats what she said!

"Same hole deeper every time" that's what she said.

Hmmm. About you orienting the anvils with the thinner sections to each side: That means that should the anvils break, the explosive force goes to the sides, but one of the heavy halves of the anvils could fly straight at you. Obviously, you had special effects specialists working with you, so hopefully my theory is wrong.

You guys are starting to do some crazy shit and I like it 😬

It's true. Don't try this at home. Do it in the neighbor's yard.

"Somewhere in the forest"....you guys are the best!
