Ya, I was using the wrong hair spray. Thanks for the help.

I built my gun, and I can't make it fire. My barrel is 4 ft and my chamber is 2 feet long. My ignition system is a flint spark for a lantern located at the bottom of the gun. What's the deal? Is my chamber to long? Please help me.

O.K. thanks for the info. I am using a lantern flint igniter instead. Thanks!

Hey, I'm currently building a spud gun and I was wondering if I could use a long lighter as the igniter. I would drill a hole in the chamber and stick the long end in it and seal it up with epoxy. will this work or am I an idiot?
