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.

Zeer aardige! Very good!

I was impressed with the rigid fins: there was no fin flutter at all. The rocket seemed to pitch over into a parabolic flight quite quickly, was there a lot of wind?

Thnx!
and no there was no strong wind!
the camera was taped at the outside of the rocket .
the weight of the camera is the problem.
but there was no parachute needed.
the rocket goes horizontal down.

Ah yes, I see. So the Clifford Heath simulator probably expects all the weight to be on the centre line of the rocket. It may give you a higher estimated altitude than you achieved in practice. A lovely flight, though!

The rocket rolls quite a lot on the way down. Are you worried that the camera will roll to the bottom just before impact, and perhaps be damaged?

We call that type of recovery a "side glider" We used that recovery system on our X-4, X-5 and X-6 rockets. The drawback that we discovered with that system is that the rocket spins on the way down. In your video the rocket does the same thing producing a "sky-ground-sky-ground" view. This would ruin any video that was taken. (back in 2003 the cameras were not as powerful) and were slower to adjust to light and dark conditions which would cause the camera to "get behind" with the light and dark adjustments (it would adjust to the darkness of the ground just in time to look at the bright sky and vice versa). We also had problems with the local wind currents destabilizing the side gliding rocket and sending it into a nosedive.

Nice Avatar. Is that an animated GIF?

Okay. Thanks for the info. It just would have been cool if you could make animations that well. No problem!
