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.

New to water rockets from Czech Rep

Post by Matej » Sun Oct 30, 2016 5:28 am


Just discovered water rockets and got quite excited by the performances of those little guys. I want to build a rocket launcher using the classical cable tie style as described for example here: http://www.uswaterrockets.com/construct ... torial.htm . Now my concerns is that in Europe it is very hard to source imperial dimensions PVC tubes. So my first question is linked to the use of a 20mm (OD) PVC tube as launch tube instead of the 1/2 inch one. As the fitting with the bottle would be less tight, I am worry the guiding of the rocket during the launch phase won't be so effective. Does anyone has experience with that ?

It seems that this topic was already adressed a few times in this forum, especially here: http://www.wra2.org/forum/viewtopic.php?f=46&t=797 . But unfortunately the link is dead....

Thanks !
