Introduction: 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
Step 1: Materials
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
Step 2: Glue and Finish
just drop the spring down the end that wont fly out and super glue it in and you should be finished
Step 3: Fireing
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
We have a be nice policy.
Please be positive and constructive.
