Water Rockets!




Water rockets are really cool!  We made our own water rocket using recycled materials that you can find around your house and then launched them in a nearby park.  We had a lot of fun running around trying to catch them as they fell down from the sky.

Some things we observed:
 1. You can launch your water rocket about 4 times before the fins start coming off.
 2. The less water you put in your rocket, the higher it will go.
 3. The more air you pump into the rocket, the higher it will go (but this also makes it a bit more dangerous when launching, so be careful)!

If you would like to make a water rocket, here's a list of supplies you'll need:
 16 oz water bottle
 cardstock & cardboard
 paper towel tube
 fabric scraps or construction paper
 glue gun
 sand paper
 ruler & marker
 ping pong ball

There is a special launcher we use, manufactured by Pitsco.  However, you could craft one yourself using some PVC piping, rubber tubing, and bicycle pump.
