Made my first Pneumatic today out of a coke bottle and a valve i got off of some sort of bag that was made to hold water cant get any acuall pics at the moment but here is a diagram and a quick animation of how it works.

My ammo is anything from Airsoft bbs, spitballs, mini spud slugs.

For some idiotic reason it wont let me open any of the other pics took i was gonna make them smaller but it wont let me for some reason (damn technology) lol.

Here is one it did manage to let me do ill get the other up as soon as i can.

It is going to be pretty hard to move that valve because of the pressure acting on one side. Are you going to have a schrader on the side of the coke bottle or are you going to fill it using a different method?

EDIT: Damn KVINCEO beat me to it.
