Introduction: Thirty Second Party Popper Cannon

This is a quick reloading party popper cannon using a piece of tube which fires a pop-rivet a fair distance.
There are similar designs around, but the novelty here is the 9/32" tube which is a push fit into the popper. A padded lollipop stick (as in another design) may make better ammo, but I was aiming for minimal reload time.
Usual warnings apply - DO NOT FIRE NEAR PEOPLE OR ANIMALS. The 'meow' in the video is Eric, and yes, I did check that he'd gone before I fired it. Pedants will notice that the cannon took just over thirty seconds, but I did spend some time showing items to the camera.
This is my first Instructable and video (using Video Edit Magic).
