mini potato cannon caps

A MINI POTATO CANNON!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Boost Mepls boost me if you want too!!!!!!!!!!!!! annnnnndddddd... its FREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!!!!!!!!!!!!!!!!!!!!!!!!!I have a big potato cannon and I wanted to make a smaller one soooo I whipped this thing up in freecad. there are two caps one for the front and one for the back. it's easy to assemble. for the chamber you will need some 1inch pvc pipe, cut it to 3 and a half inches, you will also need to drill holes for the two wires to go through, look at the pic above to see where the holes go, for the barrell you will need 5/8 in pvc as well, cut it to about 6.5 inches long, you will need to pound the barrell into the front cap. hit it until it's about flush with the hole it goes through DO NOT MAKE IT FLUSH WITH THE OUTER CIRCLE, once it goes in its not gonna come out unless you break the cap. now be careful where you point it!!!!!!! I (accidentally) shot my lil bro with it and it left a pretty big welt.for
