water bottle rocket launcher

just wanted to share my version of an instructable. my prototype is shown here finger tight (pvc has not been glued). since these were taken, i extended the pipe to the bicycle pump, and a string to the launcher, to improve the safety of the current prototype. my son and his friends love it.

My merit badge instructor made one kind of like this, same desogn with the things that hold the rocket on the PVC and the bigger PVC that you pull down. It was pretty much the same and it worked awesome! Go PEPSI UNIVERSE!(my bottle rocket)
