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

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.

Very nice! Seems it will work fine. Did you try it?
Do you have the bottle inner (launch) tube fixed or loose?
Thx

First of all, thank you.
Yes, I've already try it but unfortunately, the rocket wasn't very good. It was too heavy and it flew crazy.
The first tests:

The rocket handler is just a stick resting inside the hose.

Hi PTRockets
Your gardena works pretty well! I hope my gardena will work as good as yours.
Just a suggestion: there are small cameras like the key camera or d001/md80 that are very small, light and cheap. You can find them on ebay. I have a d001, the quality is not good for a action camera, but it was very cheap. I suppose the key camera is better.
