Pneumatic Hammer Powered Catapult! 

"Don't try this at home, this is stupid" -All great men of science

You thinned the board the wrong way, you went top to bottom, next time thin side to side. Cool idea!!!

Newest innovation from the Finnish space program:

Please give Nelli a spacesuit before you launch her into orbit.

Rename the channel to "Crazy Man With Tools, also a Wife and Cat"

Take two Finns with some curiosity, a good sense of humor and a little science knowledge, add a camera and some tools and see what they come up with to entertain themselves and us. Perfection!

Yes, do the spring steel version. Spring will store energy and hopefull give all that energy to the launch object.

Normal Finnish sport in the Snow 🤗. Great photography guys, thanks for sharing.

6:35 "Almost success" is a great way of describing a failure! :)

It's also the log-tosser five million!

When the video started and I saw you standing there with the cat I had a wave of panic for a second... Lol.

“Don’t try this at home, this is stupid”... the catchphrase of literally everything I want to try at home

id make a steel "attachment" that puts a lever point that pivots on a bearing to the frame. i could see some cool stuff being laucnhed into the stratosphere

The slowmotion whistle of the air escaping is so satisfying

"Don't try this at home, this is stupid."

Part of the problem on the second run is that the lever never got a chance to accelerate properly; it was hit by a piston that had already reached a high-energy state. Having the pivot and the Smashinator welded to the a large plate would fix it.

I would love to see a Nellie compilation vid- I love friendly cats like her.

"That was three, so I think we're going to try five" 🤣

The spring steel one sounds like a great idea. If the ratio between the arms is big enough you might get things supersonic which would be incredible although I don't know what kind of setup would that take or if the crazy forces involved would be out of the possible even with steel. A movable pivot that is bolted to thick steel welded to the smashinator frame might be a good idea as you could play with that ratio instead of just with the pressure and it might be easier to hit higher speeds that way.

I agree Lauri,a spring steel teeter/totter system(pinned at middle)would work like gangbusters. I couldn't help but notice Nellie was giving Annie alot of"kisses".HAHA!!. The drone view of the lake was very beautiful,it reminds me of how it looks here in the states.Excellent video as always.😎👍

Bonus points for the well-fed cat!

Run Nelli. Run away!🐈😂 The soda bottle went pretty high, but I really liked how the see-saw lever flips up and over the Smashinator.👍 Finland's version of Tossing The Caber. 😂👌

Some people wait for christmas or new year. I wait for frozen lake videos!!! it's the most wonderful time of the year

It looks as if Nellie has grown lovely thick fur for the winter. My cat solves the same problem by staying indoors and on a bed.

The spring steel upgrade sounds like a very, very good idea!

We love this channel … most useless fun stuff in the world! Hahaha ...

Beautiful winter shot of the lake, glad I stuck around!

The Finnish space program is off to a good start

Try using something round as a pivot point!!! Another good video as always though, keep it up guys!

Looks like the piston is traveling a long way until it hits the beam. Then the beam accelerates for some centimeters and that's it because the piston has lost most of its kinetic energy. I think it would be much better if the piston was in contact with the beam from the beginning somehow. Maybe with a smaller beam that stands on the larger one and protrudes into the cylinder. Of course it would add to the over all mass what would also be a downside... But the bottle would accelerate over a much longer way and the beam would not break as easy due to inertia because there wouldn't be as high energy peak. Would be worth a try I guess. Of course the whole smashinator should be fixed to the ground then too.

Beyond the press.... resupplying ISS SpaceStation, one bottle at a time. 🤣👍

This is the brand new finnish military equipment.

That thing makes the coolest noises in slow motion. lol. 8:22pm long whine followed by the crazy growl.

Yes... Use spring steel in the next one! 🤘

This is revolutionary for post to sweden and the baltic. Put a package on and it will be there in minutes.

Cool vid, use a leaf spring from a truck to launch stuff

I just saw the cat and the set-up started laughing!

Atlas said" Give me a lever long enough and I can lift the earth". I say "Change the fulcrum and I can accelerate the earth to light speed"!

You will definitely take the Finnish space program forward. ;) Keep it up.

Take a look at 'MythBusters - Seesaw Saga ' on RU-vid. They tried something similar and had similar problems with the lever breaking.

The snow looks beautiful. Finally. ❄❄❄❄❄❄❄❄👍

You guys are so awesome!! And you guys are so funny !! I'd love to see springed steel! That would also so cool !!!

Can't wait for the years frozen lake videos

Sort of reminds me of the physics experiment where you break a wood ruler with only one piece of paper...

I've been watching y'all's videos since month 1 and I'm still blown away by how beautiful the area you live is.

You guys sure know how to have a good time

Hey Lauri.....steel catapult beam, fixed pivot point(hinge), anchor Smashinator to the ground = new altitude record!!!

Stabilize the frame of the Smashimator with forklift forks. Keep a downward force so it doesn't jump.

“Molten lake” Are you guys living in a volcano 😂

this is still my fav machine you have. love seeing new crazy stuff like this

I love you crazy people! Can't wait to see the improved launcher :-)

(crazy hooting noises and giggling echo down the hall) "must be the new hydraulic press video..."

Turn the smashinator downside up and make a launcher that way🧐 the piston would push the projectile.

The spring steel idea is good, only thing I would change is to run a tie down across the fulcrum so the beam wouldn't launch as well

There is snow everywhere and he’s like winter has been really warm 🤣

Really hope to see the steel one :D

Come back from my workout to see a new BTP videos. Fuck yea!

Wood grain fracture make things unpredictable. Just use a leaf spring with a cup on one end and a Smashinator target on the other end.

I swear ever video you guys makes it the middle of winter… do you ever not have winter??

A leaf spring from an old car would make the perfect lever.

In order to not loose the energy the pivot / balance point needs to be fixed- the wood is jumping expending energy instead of transferring it to the end, consider a teater totter design- always love your experiments

No No no No.... *NOT PEPSI!!!* .... oh wait.... it's just A Pepsi..... Not little kitty Pepsi.. *phew!* lol

You should use expanding anchor bolts to attach the Smashinator directly to the frozen lake. You could use the whole ice sheet as counter mass to the acceleration of the piston.

At least the finish space program retsart with brend new idea and well known technology. Keep on the work for the best :D

This reminds me of when Mr. Wizard broke a board held in place with a sheet of newsprint. Inertia is a bitch.

i think it would also be cool to make a reverse smashinator too where the piston goes up and you can just put whatever you want on top of it

I live in South Texas and your channel is basically the only thing that reminds me that other places get real winters.

If you attach the fulcrum of the lever to the base of the Smashinator 5,000,000 it will bounce up along with Smashinator, giving you much more movement when the piston comes down.

The sping lever will be crazy dangerous

Ok, that was satisfyingly juvenile :)

You needs stunt double for Nelli😂

So, dig a hole in the ground, then turn the Smashinator upside-down and put it in the hole and just put the soda bottle down inside on the piston. Viola, no broken boards!

The stuntman could be drax from infinity war: "its ok quill i can take it!"

Maybe stupid but so much fun to watch!

When you stepped over that beam I thought my god what a nut shot

Super creepy headless doll

Spring steel will be epic! Do it!!!

I would love to give you the extra cold weather we are having in the US.

3:53 Thomas The Tank Engine falling of a cliff

Just watching Nelli licking Anny's hand for like a minute and a half was worth it

You should use a rounded surface for the block that the catapult pivots on so it rolls over it and doesn't waste energy crashing into it instead.

Maybe reinforce the wood with metal strips and make a fixed pivot point that may fix your problem with the wood breaking

Flip the launcher bar over so the cut part is on the bottom. The top is in tension, so you want the straightest, longest, most continuous grain you can find along the top.

It looks like you cut the log with the grain of the wood, which allowed the wood to separate and break along the grain. Try rotating the wood 90 degrees and it will probably be much stronger.

I saw you do a oxygen and acetylene explosion a while back. We did that stuff when we were kids. We found that about a shot glass of gasoline, mixed with a garbage bag full of oxygen worked much better and was cheaper to do. A lot more powerful.

I would love to see another brake disc test video with different kind of brake discs (Motorcycle, small Car Disk, Huge Car Disk from an SUV, maybe evene bigger disc...)

So THIS is why they were drinking orange soda in the live NASA Space Station feed...

You could remove the frame from the smashinator 5,000,000 and build a frame to stand it the other way up - so the ram is firing straight up - to create the launchinator 9,000,000 - to avoid problems with broken levers.

Nut buster 5000.

Nellie, - "My boyfriend thinks I'm faaaat!!! WAAAAHHHH!!!!" ... Nellie needs to go on a diet, lol.

you two make me laugh.

Relly nice! I think spring steel will be awesome! Because that will bend, when hit by the piston - then spring back. That will probably increase the catapult effect even more, than if you just have a rigid bar that doesn't break

Hola, tienes que evitar que la plataforma del pistón neumático se eleve porque quita recorrido de empuje sobre el listón de madera. Saludos desde Montevideo Uruguay.

My goodness that boards a really heavy duty like 8x8 or something like that n it's thrown like a toothpick. I only just recently found you guys and i can't get enough i love watching. Keep up the stupid dangerous stuff lol.

With his glasses on his beanie, looks like something smashed right through his right lens. 🤣

You have such fun toys.

The catapult is a great idea with huge potential. I hope to see a refined version in the future. I don't understand why you want to use spring steel. Is it because a more rigid steel would break? Moomin spotted, by the way. I love the Moomin books! What a cultural treasure you have in Tove Jansson.

"The Smashinator smashes as usual"

In lever mechanism support beam contact point should be pointed or rounded. Contact time of impact is very small because or two contact point in your system. Sudden change in support beam lever point

there is snow in finland? here in south sweden it's just rain :( maybe i should move to finland :D Nice video 👍
