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.

Launch Day 7 - HHWRSA

Post by thampson » Sat Sep 20, 2008 8:54 am

We had a launch day today and we were concentrating on the parachute side deployment system. We only managed one launch and Im happy to say we were very successful with the deployment, but the wrocket landed 195m downrange in thick bush. Here is the video


We got our wrocket back thankfully, if you want to read the writeup of the "adventure" we had getting it back look at launch day 7 on our blog site http://wrocket.hampson.net.au

We want to do a few more tests on the deployment system, but we are happy with todays results :)

That was mighty courageous of you to launch with that much wind. I can hear it blowing the microphone of your camera. Glad you got it back though. Look forward to seeing more of your adventures. :)
