Ok im working on something and i need help with it.
What gas (in a canister) would move something attached to it (like a chair or something) if it was sudenly released?

sorry if you dont realy understand it ^^

you mean like so when you release the gas you'll go forward in a chair with wheels on the bottom, like on brainiac :P

any gas should work, it depends on the pressure that its kept at in the cannister, and the speed that its released at i think. not sure though, i don't think you'd be able to build it though would probably be easier to buy one, google gas powered chair :)

Any gas that is compressed enough should make anything move.

Fire extinguisher gas should works.. thats carbon dioxide right?

Yeah, fire extinguishers work.
When we moved buildings at school, they were silly enough to leave all the old fire extinguishers in a room in the old building... that was a fun week =]

Yeah, anything under pressure really, but i highly doubt your going to be able to get ahold of some compressed gas clyinders, unless your teachers ALLOWED to get and use them
