A great toy that demonstrates the basics of rocketry. A plastic rocket is partially filled with water, air is pumped in with a little hand pump, and upon the release, the air pressure pushes the water out the back, propelling the rocket. About 1-1/2" dia x 6" long. Flight tests suggest loft and distances of about 50 feet each are achievable, when the right water/air mix is found. However, since operations lost their rocket on the roof, testing was terminated before final results could be obtained. Clearly, these are good fun for all ages. It has everything you need... Just add water!!
