Welcome to the Water Rocket Forum, sponsored by The Water Rocket Achievement World Record Association.

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.

I use the sprayer tank to add water to the rocket. A three way valve on the bottom of the tripod head keeps the air line dry. After water is added the air valve on the sprayer tank purges the launch tube. Switch over to the compressor line and I am ready to pressurize the rocket. A bicycle pump is used for that.
