About this 3D model

Before anyone asks "Why?", my answer is this: "Just because, okay, get off my back" Party poppers are fun, but making a firing mechanism just makes them more fun. I may make a six-shooter version next. To load this device: 1. take a standard party popper (http://en.wikipedia.org/wiki/Party_popper), and insert it into the barrel, thin end first. Push the Hammer all the way forward (while pulling the trigger slightly), then release the trigger so that the latch catches the hammer. 2. push the party popper all the way into the barrel, so that the thin end protrudes, then push it back about 1cm (the gun needs a little wind up to get momentum to pull the string). 3. loosen the string, then wrap it around the hammer, pulling it snugly through the notch to secure. 4. pull the trigger to fire.
