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.

This is really cool. I hope they can perfect this and start making some more outer planet probes!

Read more about it. Looks like the hype was just hype so far.

Yes, that article is from 2015... and since then, I've looked in vain for any confirmation that it works and found none.

Here's a more recent article from this year:
