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.

hi bro (although your nick suggests you're a "pretty girll")

how does a parachute work in a water rocket?

1) it slows the rate of descent of the water rocket, prevents damage when it lands (instead of crashing down at high speeds!)
2) you need to design and make a successful deployment system, that opens at the right time, ie: not while it's going up or when it already crash landed. Preferably at "apogee" or at the highest possible height.
3) materials can be plastic bin bags (large rubbish bags) or old umbrella material, or the best, parachute material!
