Post-Apocalypse Air Cannon
My company was going to throw away a perfectly fine T-shirt cannon. I saw it as the start of a Mad Max-Isa weapon. While all the mechanical looked right, it had a large Gillette disposable razor as a barrel that had to go. So, I created a large-diameter barrel out of PVC and a hand-stitched leather handle. A new paint job and Hello Kitty to add a little crazy.
