Fill this rocket with water, pump a few
times, and let the pressure buildup propel it into space about 35
feet (not outer space, but a good chunk of the lower atmosphere).
On our first official test run we were very impressed with this
product, but with practice it got even better. Perhaps this could
be the answer to NASA's technical and financial woes? We certainly
hope so. The rocket is 7" long, made of sturdy red and white
plastic, and comes with pump and complete instructions. Our water
powered rocket makes a great gift for any kid or adult.
