High powered Water Cannon
--------------------------------------------------------------------------------
My friend and I had water wars with our neighbors back in the day. Standard water balloons just weren't doing the job. We knew we needed something with more power. I originally got the idea from my water rocket. I thought; what if I held the rocket - a blast of water wood shoot out with great force. From that I came up with this idea.

My friend and I actually made two designs. One cannon was huge, but was portable and did not require a constant air/water hook up. The other was much smaller and had the ability to shoot a constant blast of water.

Design #1

This water cannon had two three inch chambers which were connected via tees and PVC nipples. There was a flexible hose which was then connected to a ball valve and then to the nozzle. We first thought about using an electric solenoid valve, but we changed are minds and thought this would be simpler. The two tanks are held in a large backpack, which was worn. The design looks very similar to a flame thrower. - No ideas there kids - .

Theory: The chambers were filed half with water and then pressurized to about 90 PSI. When the valve is opened, the air pressure pushes the water through the nozzle at a very high speed. More Pictures

Heh, reminds me of the super Soakers with the back pack. Used to spary the hell outta people with that thing when I was a kid.

Nice design though, a while back I had an idea for something like this but just found shooting spuds to be more fun. But I bet this gun stings when your hit.
