This is a fairly easy way of making an awesome 1/2 inch pnuematic pvc luancher.

Step 1: What You'll Need

most of these things can be found in any hardware store besides the bike pump, as for that you're on you're own, I've had that mounted on my road bike for several years and is probably discontinued by now, but you could probably find another one in a bike shop that'll work for not too much.
*all pvc is 1/2 inch in diameter*
atleast 2 feet of pvc pipe
1) T
1) 2 liter bottle
1) pvc cement
1) electricians tape( or any other type of strong tape, but I like the feel of electricians tape on the handle)
1) pvc ball valve

Step 2: Assembly

Assembly is pretty simple and straightforward- the pump I have fits snugly inside the 1/2 inch pvc pipe. as you can see first of all you should pvc cement together the 3 pvc pipes to the T one side to the 2 liter bottle one side down to the pump and one side with a small section of pvc going to the ball valve. you can make any of these sections any length you like, but the longer the barrel (up to about 3 1/2 feet long) the better. pvc cement the pump, 2 liter bottle, and ball valve to their appropriate pipes. but do not pvc cement the barrel tot he ball gauge because It's easiest to remove the barrel to put the ammo in.

Step 3: Have Fun!

Ammo I've used-
AA batteries (must be wrapped in duck tape a bit to be perfect fit)
Baby cut carrots
Grapes
Mini Marshmallows (good for shooting indoors and not destroying anything )
and marbles.

I am not Liable for any injuries that might happen to come about because of this instructable..
and do be safe- don't shoot AA's or marbles at any one... it could really hurt(kill). =p

Here's the video displayed in my animated gif.

    I honestly highly doubt you could find threading of that exact size.. i've tried to find a size before and failed.. so i used 1/2 inch pvc pipe and pvc cement it to the inside of the 2L bottle..

    yes i know of that way but i wanted to fit a full bottle of (generic Fizzie Pop) to a rig that used the CO2 pressure to force the drink up into a cupso it is a case of drilling a hole a spare lid inside the internal seal and epoxying it in. but thanks for the advice

    i used a pvc cap and drilled a hole in it then shoved a tire valve i cut off a tire in it to pump it up it makes it easy to pump up.
