Remote Controlled Confetti Cannon
Baking Soda and Vinegar Cannon
Oh man, this is TOO COOL!!!! In Texas, combustible cannons are illegal and considered "zip-guns". Pneumatic cannons are generally considered air-guns and anyone over 16 can own them. I don't know WHAT to classify this as, but I will eventually make one anyway! What kind of pressures can you ultimately get?
That's a good cannon! I made one almost exactly like this that shoots Nerf Footballs about 300 yards. There's a few safety considerations for the next one I make. Place the air nozzle and gauge where the coupler is. This way, you drill through two thicknesses of PVC instead of one.You can get a better seal and the connection is more solid.I am starting to shy away from PVC as an air chamber. I haven't had any problems at 100psi, but if it did rupture, well, PVC doesn't show up on x-ray. It would also be like a grenade! Metal air chamber is preferable. Some people use fire extinguishers.I have used the cannon for confetti, apples, footballs, and water. Be careful using water because it WILL recoil and could possibly cause a "hammer effect" and damage your cannon.

I was in Communications in the Army and we used the eraser to clean the electrical contacts for the handsets. It works great for battery contacts on household electronics, too. Just erase the oxidation.
