PVC Potato Launcher or Paintball Marker

I was only able to find a adapter to 2" pipe. However it can be reduced further (about 1/2" or if you have a lathe, .68" is the approximate size of a paintball [it can vary]). It can be used in the current state to fire paper wads containing loosely packed paintballs to achieve a shotgun effect. I am not responsible for injury or damage incurred by this device as it can be dangerous if use carelessly.
