Dual Option Water Powered Bottle Rocket

Most bottle rockets are powered by air, but I've made this one powered by water. A 2 liter bottle will go about 20 feet off the ground. This is a dual option rocket launcher. If you want to launch 1 at a time, close the ball valve and put it on the left side. To fire both, open the ball valve.

Step 1: Materials

You will need:
4-1/2" pvc elbows
1-1/2" threaded on 1 side t joint
1-1/2" ball valve
5-3" long 1/2" pvc pipes
2-1" long 1/2" pvc pipes
1-6" long 3/4" pvc pipes
1- 5 ft long pipe
1-valve clamp
1- of the things in the pic below
duct tape
water-proof tape
bottles
candle
