    is the bike valve 1-way?
    {can you pump it, take the bike valve off, and walk around to shoot it so you dont have to carry a bike pump when you walk around??

    My bad, don't use pop bottles and they are rated to 70-80

    Please for the love of safety do use a pop bottle. Yes, I know they are rate to around 80-70 psi but under constant release and compression cycles it will weaken the plastic and cause a explosion. These bottles exploding could cause hearing damage and lacerations due to plastic shrapnel. Spend the extra 20$ to buy some proper pressure rated PVC and seal it with JB weld.

    Hi, I'm having some trouble connecting the coke bottle to the pipe. The pipe I'm using has an outside diameter of 15mm and my inside diameter of the coke bottle is 22mm. I can't think of any ways to securely and air-tightly connect the two. Any ideas?

    Sorry for late reply, but how about using super glue and glue it on then duct tape it?

     Too late mate,
    I got a connector piece from 15mm to 22mm then glued a small piece of 22mm pipe into the mouth of the bottle.
    Thanks anyway though.

    Where did you find the ball valve and bike tire valve? I looked for it at lowes and couldn't find it.

     actually talleu this is a muzzle loaded air cannon so therefore you could only  get 1 shot out of this air cannon per shot and if you had a pvc pressure chamber and make it larger than your barrel you could use 125 psi out of this air cannon use pvc primer and cement it sets quicker and is cheaper than epoxy it melts the pvc together and it makes them  chemically "welded" together so therefor it has a stronger bonding strength

    I'm confused by "Also shoots marshmellows for hurting your friends!" - marbles wouldn't?

    Marbles dont hurt your friends: at 150 psi, they kill them.
