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

Since our founding in 2003, we've become 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.


Hello Everyone. It is that time of year again. Time to approve changes to the competition rules for the new year.

Take Peek ... or don't

Stumbled upon these water rockets a few weeks ago so I decided to throw something together. Hope to have the whole thing controlled from my iPhone with Bluetooth later today.

Awesome launcher! The release mechanism is sort of what I had in mind for my "dream launcher" but I couldn't see a way to do it without machining my own parts. Is that what you did?

I especially like your ability to fuel the rocket with both water and air pressure after it's mounted on the launcher.

Great Launcher!.

I am currently building a system similar to this one at the moment

I take it that there is a one way valve on the water input?

Yes, machined all the parts, there are check valves on both the water and air.
