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.


Hello Everyone. It is that time of year again. Time to approve changes to the competition rules for the new year.

Hi Todd,

I used one of your older photos from the forum on the standings page.

http://www.wra2.org/WRA2_Standings.php

Let me know if you want a newer photo.

What would be really cool is a still photo of your dragster launching. PH:

Hi Lisa,

I had a look and I havent got a good resolution pic of of the car launching unfortunately.

We are just finishing building our launch cage with a guide rail (which i will post some pics of once its complete). I will setup a remote camera to try to get a good pic of the current car launching out of the cage when we test it, that should make for a great pic :)

Hi Todd,

Thanks for the reply. I hope you didn't mind that I used one of the older photos that you posted to the forum. It will work for now and serve as a placeholder until you can take a new one with the cage.

I look forward to seeing your launch cage.

Which WR dragster class do you think will be most popular?

My guess is that "time trial" will be more popular due to the shorter track needed to compete.

Our cage is nearlly finished so hopefully get some pics up in the next day or so.

I think the time trial class will be popular, but I think cars may be able to compete in both classes for a little while before it gets too specialised.

The older photo of the water rocket car is fine for the moment :)

Lisa,

Here are 2 pictures of the water rocket car launching out of the cage. I hope one of these will be useful to put on the competition page :D
