The Pressure Tester Pen Gun

this is mostly a dumb toy but it is dangerous and can hurt people you didn't get this from me

this pen gun has a numerous amount of modifications you can make.....but after you take the tire tester apart throw away the little round thing and keep every thing else...you need super glue

just drop the spring down the end that wont fly out and super glue it in and you should be finished

launch by using things like unsharpened pencils and any thing with out a point you fire by simply pressing down with your thumb and letting go
