How to Build a water rocket
Who knew some plastic, water and air would be so much fun? If you like rockets and explosions, you probably knew. And so did this guy, who shows you how to make an awesome water rocket that can shoot over 200 feet! Before you try following along with the rocket build, you should gather the materials—5' long piece of ½" PVC, small length of 1½" PVC, glue, ½" PVC "T" fitting, 2 PVC caps (½"), ¾" hose clamp, 7" zip ties (9 of them), duct tape, 2-liter plastic bottle, and a bicycle pump (or air compressor).
