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 agree completely, approaching a pressurized rocket is unsafe; come up with a better way.

You could use a ball shutoff valve, operated by a rope. With a pulley, you could pull one rope to open , one to shut...

Like an emergency dump valve, but in line with the rocket
Ahhh! Now that makes perfect sense! Good thinking!
