This is a project I made for a challenge on the Brass Goggles forum
. The challenge was to make something to aid in the act of thievery or assassination. I decided to make a blowgun disguised as a cane. It's pretty simple. It's a CPVC tube with some attachments that allow the handle to be threaded on and off the tube. The darts are made from these instructions
. It shoots through cardboard and 1/4 inch into plywood.
