I was bored one day so I decided to make a gun to shoot my brothers with. I needed a projectile that was soft, readily available and inexpensive. The answer: marshmallows! A marshmallow gun is usually very simple: a tube that you put a marshmallow in. You blow in one end and the marshmallow flies out the other. I wanted to make something more complex. I got a one-way air valve, some PVC fittings and a ball valve and created...(drum roll)...the pump-action marshmallow gun!
This is my first instructable so feel free to leave comments and tips.
Step 1: Materials
4 1/2" PVC 90 degree joints
1 1/2" PVC coupling
1 1/2" PVC ball valve
(I think you have discovered by now that all the PVC components are 1/2".)
1 PVC tee
1 PVC one-way valve (Look for it under the name "check valve")
1 PVC end cap
Assorted lengths of PVC pipe (1/2", of course)
Dowel that will fit into the pipe
