Marshmallow shooter updated

Yesterday I headed over to the local Home Depot to pick up some parts required for the marshmallow gun.  A quick list of the items that I picked up.

2      1/2" PVC pipes
1      1 1/2" T Pipe
3      1 1/2 to 3/4 Reducers
1      1/2 PVC Ball Joint
1      Tire Valve
1      Mini Bike Pump
1      Pipe Cutter

I have not had the chance to take pictures and it was only a quick build to see how it works.  I have not used the cemet to hold the parts in place.  I am not to happy with the PVC ball joint as its not an easy way to fire the shooter, but I dont really know of a small and inexpensive way to enable quick firing.

Basic setup is

Mini bike pump to the tire valve. 
Tire valve connected to 1/4 hose that is connected to a barbed connection to the reduced side of the T-Pipe.
Bottom part of T-Pipe is closed off, and the adjacent side has a reducer with the ball joint and then the 1/2 pipe at the end.

Testing without the cemet was not successful as it kept popping the top, but I wanted to wait to see if I should add a bigger chamber for compressed air.  Right now its kind of small, and also I have to figure out how to mount the bike pump.  

Once again I will post pictures of it as it goes along, and if anyone has any suggestions or idea's please let me know.
