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.

Hey man, thanks for sharing a really nice design. I never thought of using slits in the bottle to make the bay for the parachute. I've always glued a small diameter bottle inside a hole for that. I also like the way you mark the place to cut the ping-pong ball for the nose. You have some clever ideas!

Dude, you should be proud of your design and the instructions. I was able to follow along just fine even though I was initially thinking it would be hard without words. Once I saw the big photos I was like "Cool! This is easy!". I'm sure your instructions will help a lot of people. Even people who use servos or solenoids can take away something from your work. Thanks for the hard work!

:D Thank you. I was wondering how people would take that with just pictures. To me its easier to show then to tell someone how to. Im glad you liked it. The comments an feed back inspire me more to get more involved with my work. An I thank you.

I'm impressed that some of you guys can put so much time into your wrockets. I'm working this summer and all I can think about at work is new rocket ideas but when I get off or on my days off I'm so tired I can't get anything done!!!

How did you attach the timer to the inside of the bottle?
