The largest, most sophisticated and ground breaking group supporting you, the serious water rocket flyer! Whether you are a beginner or an expert, the WRA2 has something for everyone.
A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.
Discuss non-rocket topics, TV, Movies or even general science here.

I want to go see it in IMAX but since it's a long drive I'm going to wait until the crowds die down before I go. Tim and me made that mistake with Star Trek and we had to come back the following week so we could get tickets because it was sold out every show for a solid week!RaZias wrote:My brother has seen it and he says it rocks...it´s better than the first.
I am going to see it tonight.
