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.

First you need to fill out a WRA2 membership application.

http://www.wra2.org/WRA2_2011.php :WRA2:

Then read the WRA2 class C rules:

A submission can be made in the class C submission forum.

Just remember that Record is calculated as the average of the two longest duration flights the rocket achieves within a 2-hour period. Duration determined from the video taken by the onboard camera by timing the flights from launch pad to ground. Results must be repeatable! Please include the date and time for the flights and the duration of each flight.

Once you complete your application you will be given access to post in the submission forum.

Good Luck!!!! :WRA2:
