Making a 330+ Joule Air Cannon

- In this Video I build an air cannon from a fire extinguisher capable of putting out over 330 Joule at 13 bars pressure. If I had bigger guts it could easily put out more energy...
It can be used as a potato canon or to launch anything that's laying around :D

Nice job! Love that you through in some math to analyze the performance. 🤙
Un gusto Amigo... Me gusta tu creatividad, sigue asi!!! Un abrazo desde URUGUAY
I've never seen a fire extinguisher with that large of an opening. Replace that silly little valve with a two inch ball valve and use a pneumatic actuator to open it and you will be blowing holes through car doors.
impressive, well done
Hi ! Be very careful using compressed air doing anything ! The Schrader valve can actually be your death sentence ! 😢
High pressure injuries?!
@@johnshipley1389 Hi ! Yes, It is just a piece of brass with a rubber o- ring that can shoot out like a bullet !
Brother home many psi a fire extinguser can handle
good job bro🎉
You've built the speargun from the Poor Man's James Bond. It was a large book from the 80's, showing lots of DIY "devices."
Sounds cool, definetly gonna try to get my hands on that book!
@@Mika_357 The Weaponeer is a more useful book, by the same guy, Kurt Saxon. Now days, having it will probably get you put on a list. 40yrs ago, it was a cool book of improvised devices. Anyway, stay safe!
very wise to not weld the tank. Simple but effective.
Arc welding galvanized steel, like this pipe, damages your lungs with zinc oxide. This has to be done carefully.
Nice build
Thank you! It was very fun!
You should use a fan when welding bro. That is some toxic smoke you're inhaling
I thought the compressor was going to explode with so many pumps hahaha nice toy
Ótimo invenção
It sure sent that pipe a long way ! Did you get it back?
After a bit of searching in the long grass I eventually found it, yess!
Yeah good
Doing a few changes you can power up upgrading the airflow
I like that idea for a portable tire inflater.
Fill it up . Throw it in the trunk.
Wife: honey when are you going to come in for dinner? Dude: soon as I’ve finished building and testing my fire extinguisher cannon I’m making for RUclips….. wife: I think we need to have a talk
imagine what could you do with a compessor instead of a bike pump
seen one in the workshop doh
Get it to fire 10 mm Steel Bearings rather than Potato Wedges then you will be talking 👍
Pumping it up with a bicycle pump was hilarious. At Harbor Freight you can get an electric tire pump for 10 dollars. will a golf ball fit in it?
I usually pump it up with my shop compressor which goes to about 9 bars. I only use the bicycle pump for pressurizing it to 13 bars afterwards, but even that sure is a good workout ;D. Whether a golfball will fit depends on the barrel you're using. But with the pipe I used it actually fits!
imagine getting shot by a 1kg metal rod going 70 mph
How many psi did you pump it up to?
I did 13 Bars wich is around 190psi, this was the maximum I was comfortable with
@@Mika_357 Thanks for the quick reply. I'm building one of these out of a small oxygen tank from a cutting torch. It should handle 200psi with no problem, if yours held 190. Thanks again!
My pleasure! In my case I was concerned about the car tire valve, it was only Rates for 10 bar max.(145psi)
What about using a co2 extinguisher that's full.
You'd be able to shoot the rod extremely far is the barrel of the air cannon was only a little bigger then it
Идея хорошая
what your neighbors saying?
👍🏽
valve is Tir valve??
Yup it‘s a Tire valve!
jetzt mit 150 bar und gezogenem lauf
Prática mente no dejo ber ni aprender nada todo lo hizo a la carrera
Pero si eres un niño, apenas un muchacho
Get your head outta the fume path! 🚩🚑
Valve is too small.. not dumping your tank fast enuff😢
Poxa caiu aqui no Paraná 😭
A grenade launcher perhaps
Are you german?
Yes, I am!🇩🇪
@@Mika_357 Haha same
