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.

400 psi Shock Pumps

Post by RaZias » Fri May 28, 2010 7:17 am

I have some experience in Mountain Bike so I know that in the market there are Rear Shocks that work with compressed air instead of a metalic spring.

Therefor there are pumps that pressurise them to 400 psi. Those pumps aren´t as expensive as the floor pumps.

But they have a cath...they are for small volumes and they work by hand so imagine the time it takes and the state of your wrists...

Where is one of them:
