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.
Post photos and videos of your rocket, launches and your onboard video or photos here. A wide variety of formats supported including attachments and embedded youtube.
The Queensland Rocketry Society recently had a Christmas themed launch day...so this is what I tried. The backslider failed as the nose got soaked in a prelaunch mishap and went out of balance. (that means i forgot to put on the top cap and all the water ended up in the cone )
Santa landed safely twice but missed the somewhat tacky cardboard box chimney we made by miles... Hope you don't mind me sharing. cheers Jeremy

I come from China, do not understand English, your information I use the translation software to view. I like water rockets, technology is the same, I hope we can become friends.
