The folks at Modd3d show us how to make a confetti cannon:
I’ll show you how to build a pneumatic confetti cannon that sprays bits of paper all over the place at the push of a button. It is safe to use and easy to build, and the confetti shower effect it produces is excellent for stage shows, dances, parties, and those times when you need to make the biggest mess possible in just under one second.
It uses a fire extinguisher, a sprinkler valve, and a plastic pipe. – Link.
