1. Cut PVC Pipe

Cut PVC pipe to the 24-inch length (or choose a shorter length for younger kids if desired).
Bob Vila has great instructions if you have never done this before.

2. Assemble Water Blasters

Assemble water blasters following these instructions from Popular Science.
We particularly like the different drilling options to create different water patterns!
