A DYI guide for how a kid can make a gun? In 2013??? I’m amazed the maker isn’t in jail, bunking above the Youtube movie guy.

You’ll shoot your eye out!!!

Found one of them in the garage the other day that my son and a friend had made. But around here they are called potato guns and they fire something with a bit more mass than a marshmallow. They get fired with a spark plug after something flammable is squirted inside.
I have a 2″ X 5ft pneumatic pvc gun with an extra tube for an air tank. The barrel tube and the tank tube are connected by an electric sprinkler valve with a switch and a safety connector. It works with three 9-volt batteries connected in series.
Potatoes got to be boring so we took some short pieces of 2″ pvc, sealed one end with plastic wrap and rubber bands, and filled them with water then put them in the freezer. Be Warned: ice cylinders are VERY Dangerous in a potato gun!
At 100 psi I can lob one about 450 feet, and they will easily shoot all the way through a wall. You could stop an intruder with it if the intruder were patient enough to wait while you fill it up with air and fetch the ice cylinders out of the freezer.
