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.

High school physics class.

This forum is for new members to introduce themselves and tell us how they got started in water rocketry.

I have to build a water rocket that has a climb time of 4.5 seconds or more and I have no idea how to make one.

Can you give a bit more details? Is there a max or min volume, what pressures are you going to be using, is there a max or min weight, does there need to be a parachute, etc?

uswaterrockets.com and aircommandrockets.com are great places to learn about water rocketry.

I think 1.5L bottles are enough. He said ascent time anyway..... And that includes launch, burn, and coast.
