Cap Gun Conversion II
‘Cap Gun Conversion IIII’ will explain yet another way to convert a cap gun into a very loud cap gun.
Take one of the revolver cap guns that shoots the plastic caps. You must fill the cillinder with either flash powder or black powder. When you pull the triger, the flash from the cap will ignite the gun powder quickly causing a blank pistol effect. This one is not as reliable as the other one, so you will have to experiment.
