Water Gun #1

Alright! Water Gun #1 is here! This is actually a cannon that blasts water at high speeds, huge amounts, and is easy to build. It also shoots water balloons...Here are instructions... Enjoy!

P.S. I assume that you know how to properly glue PVC together...And the other basics of working with PVC pipe...
P.P.S. This: P&G stands for "primer and glue". By-the-way, you'll need to cut pieces of pipe to these specs: 3"x18", 2"x4", 2"x26"

First, let me explain what everything is. The red rectangle is the air fill valve. You can get one at an Ace Hardware. This screws into the dark blue 3" plug. The 3" plug attaches to a piece of 3" pipe that is 18" long. The other end of that screws into the green 3"x2" reducer. Then, there is a 4" piece of 2" pipe. Next is the light blue rectangle is a 2" ball valve. A 26" piece of 2" pipe is the barrel.

Now, let the construction begin!

Take a drill bit that is slightly smaller than the big end of the air fill valve. Drill a hole, straight down, in the center of the 3" plug. Screw the air fill valve into that hole. Second, glue the 3"x18" pipe into the plug. Glue the other end of that pipe into the 3"x2" reducer.

Next, take the 4" piece and glue it into the 2" side of the reducer. That done, glue the ball valve onto it. Lastly, glue the 2"x26" piece of PVC into the other side of the ball valve.

That's it! You're done! Let it dry overnight (or 12 hours).

To use with water: Close ball valve, fill barrel with water, pressurize container to 60 PSI. Open ball valve quickly to shoot!

To use with water balloons: Close ball valve, slide a water balloon down the barrel, pressurize container to 60 PSI. Open ball valve quickly to shoot! Play carefully with pressures!
