This will kick your next squirt gun fight up to a 11 out of 10
Cut a piece of 1 1/2 inch thick pvc pipe 16 inches long. This will sere as the shaft of your hammer
For the head of the hammer I used a foam flooring tile.
Cut two pieces of tile 10 inches long and 5 1/4 inches wide. These will become the top and bottom of your hammer
Take one of these pieces and place a 1 1/2 inch pvc pipe cap at the center and cut a hole around it. this will be on top of your hammer
Then make a hole in the other piece and slide it on to the shaft
You will need to cut two 5 by 6 inch pieces and two 6 by 9 3/4 inch pieces
Tape, glue, or staple the pieces onto the shaft, but keep the top piece, you will glue this on later
Drill a hole in your pipe cap for the water to squirt out of.
Glue the cap on the top of your shaft using pvc cement.
Tape or glue the top piece onto your hammer.
Paint the hammer head grey and the shaft brown
Now we'll start on the plunger. Take a 1/2 inch pvc pipe and cut into a 17 inch piece. This will be the shaft of the plunger
Take a 1 1/2 inch pipe cap and drill a hole big enough for the shaft to slide in and glue it on the end. This will serve as a handle
Take a rubber 1 1/2 inch pipe cap and drill a hole in the center and slide it on the shaft
Paint the entire shaft brown
Take a 1/2 inch pipe cap and glue a grommet around it. This will slide into your 1 1/2 inc pipe and cause suction.
Use the pvc cement to connect the plunger onto the top of the shaft
Slide the plunger into the hammer and tighten the rubber pipe cap. Your hammer is now compete
Step 19: Tips
If your hammer doesn't suck up water it probably isn't sealed probably Glue a o-ring around the plunger
