Welcome to the Water Rocket Forum, sponsored by The Water Rocket Achievement World Record Association.

Since our founding in 2003, we've become 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.

No according to their rules, SC: they are counting the number of people each launching one rocket. BO:

And except for the fact that they told me the current record holder is the 693 from that school in China. I noticed they also added a new category for most launched in 24hrs. They're just making this stuff up as it comes in I guess.

Since water rocketry is probably low on their priority list, I wouldn't be surprised if they simply "rubber stamped" the most recent entry. :hopeless:

You would need a couple of good HD camera videos of the launch. If you did them all with a mega launcher, it would be easy to see how many launched and how many got stuck on the launcher or launched late and even subtract out ones that didn't fly right and crashed right away.
