Co2 powered potato cannon

I have always liked to build things and when I came across this I knew I had to make my own version.

This is a powerful cannon do not shoot at any person or animal. I am not responsible if you get hurt with this.

This is my first instructable so please try not to be to harsh. Any constructive criticism would be greatly appreciated.

This cannon can go up to 150 feet if there are no air leaks.

This is really good it's fun to see little BAMFs making cool things!! I'm really curious too though: How many shots on average can you get per cartridge?

Just realized, I was rather rude.
Great ible well documented, good photography. Great bile really.

You could always use a sprinkler valve instead. I saw excess co2 coming out the barrel. It would allow more shots per cartridge.

Question: How many shots do you get with your current set-up?

I saw this on a kipkay video a month ago, but you did a good job building it! I was too lazy to go out and find one of those quick change adaptor.

This kid is obviously a genius. He will probably be recruited by the Dept. of Defense before he hits twelve.

Amazing. simple, effective, and can be made with no special tools. my only question: where do you get a 12gram CO2 adapter?

Heres a tip: I notice you attached the metal pipe assembly to the barrel several inches above the base of the barrel. if you attached it further down, or even onto the end cap itself, you could get more efficient gas channeling and not have room at the base of the barrel for things to get stuck.

very well written, simple, well documented, great photos. Everything an Instructable should be.

I may modify this design into an under slung grenade launcher for Airsoft.

Keep up the good work!
