i was thinking of buying one of these tire inflators and just screwing on a schrader valve with no valve so its just open and the other end in pvc. it would shoot marbles but it might use the hole tank to shoot 1 marble. realy easy to make and simple.

you might want to modify the shrader valve, take out the core and drill a bigger hole in it, also use a smaller and lighter ammo, like a toothpick

why that co2 would plenty enough to send a marble flying! tho he would need a longer barrel

What are you talking about co2? He said he was going to hook it up to a tire inflator.

The yellow thing in the pic holds CO2 tank internally... So you dont need to drag a hose around, just that little dinky thing. As others have suggested, a longer barrel is needed.

Oh, sorry, I can't see the pic for some reason on my computer, so I was just going by what he typed.

i never used one of these co2 things so i dont know how they work. it would be nice if you could just pull the trigger and some co2 comes out. that way you could shoot it 4 or 5 times before it runs out.

you just screw one of those disposibal co2 cans in and when u press the botton it releases the air

but how much and how fast, that my friend, is the question.
