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.

The forum accepts Google Videos and You Tube videos or if it is small (less then 5 MB) as an attachment. Just upload to You Tube and then use the GVideo or YouTube buttons to insert the URL from You Tube or Google Video.

I think you just have to click the YouTube button on the top of the editor.

Just click the youtube button once and then paste the URL of you youtube video ( and then click the youtube button again. If you do it correctly it will look like this:

Have you given any thoughts toward putting a camera on your rocket? You will be amazed by what you can see if you do. People nowadays are so addicted to "YouTube" and "MySpace" that they are always eager to see unique videos. They go crazy for rocket onboard video!

I must have missed this question. If you go to the camera department at Target or Walmart, they have these little cheapo digital cameras for under $20. Some have more features than others. I found some in a thrift shop last year and they were around $19 each and had a slot for a memory card and everything. I figure if it crashes, no big deal. It's really small and so I think it will not break easily.

That's all you really need.
