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.

Do you use the 45° wings for downforce as well as for yaw stabilization?

You are going to use 3 nozzles of 15mm each.

I presume you will be using 15mm gardena nozzles at 260 psi.
(if the pump is the Topeak JoeBlow Ace Floor)

The 15mm female part are only connectable with a plastic quick-release.
(there isn´t a metalic quick-release for 15mm).

Therefor I wonder if the quick-release won´t blast at 260 psi... :roll:

I was in Harbor Frieght and saw some fully brass disconnect style (gardinia type) fittings very cheap. Was thinking about getting them to try but have too many irons in the fire now for a new releas project.


Any opinion can be raised, but few grow up to become facts.
