Step 11

Make a couple more holes in the 1 inch PVC pipe. Put one an inch from the end. The other should be one and one half inches at the other end. Use the one inch PVC to create a handle. Connect it with a handle with some nuts, bolts and washers.

Step 12

Place the pump rod into the shaft. Immerse it in water. Pull the pump rod. This will fill the gun. Now you just have to aim the gun. Push in the pump rod. This will shoot the water out of the end cap.
