These little water rockets have been around just about forever. The water rocket is a little less than 6 inches tall and the unit comes with a filling funnel and combination pump/launcher. Just add some water to the rocket, place the rocket on the launcher, pump some air into the rocket and pull the trigger to launch. The compressed air inside the rocket forces the water out and off it goes. NASA requires a T minus 10 count during all launches (it's some kind of obscure federal regulation). Manufacturer recommends rocketeers over 8 years old and we highly recommend outdoor flights only. This is one of those things that everyone should have sometime in their life. Lots of fun for not much money. |
