i have just landed the coolest school project ever with the task of building and using an air powered potato gun, well really a gun that fires anything....
anyone got any useful sources for making compressed air powered rather than hair spray/propene powered??
thanks

my dad and I made a potato cannon when I was like 12, I don't really remember what we used but I do know that the potatoes were flying out of that thing at like 50mph (we had a family friend who had a radar gun) after we accidentally broke a window my mom made us dismantle it :(

I use butane. I'm not sure you could get sufficient pressure to really send a potato using air pressure.

ive heard that compressed air can be just as good, getting 200 metres off 100PSI.....basically, this is for school so it doesnt need to be huge

So, nothing to do with 'Sir' Richard Richard, Edward Elizabeth Hitler, or Little Dave Hedgehog, then.
Ah well.

It's just you. 'Spud Gun' is a character on the BBC comedy, 'Bottom' starring Ade Edmondson and Rik Mayall.
