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.

Racial or sexist remarks of any kind, pornographic images and statements, and illegal content containing drug use are absolutely forbidden. Derogatory comments against other groups based on sexual orientation, age, class, IQ, ethnicity, political preference, religion, nationality or similar features are also strictly forbidden.

      2. New members (as well as veteran members), should be treated with respect (See Rule #1) even if they ask a question that has been answered a thousand times before, simply refer them to the proper thread(s) that answers their question.

      3. Do not post any personal information (i.e. complete addresses, phone numbers, passwords, personal identification numbers, or any other information considered private) of yours, or others. This is for your protection, and the protection of others.

      4. Each individual is allowed to have only one account. Duplicate accounts will be deleted and the creator will be subject to disciplinary action. All accounts require a valid e-mail address. E-mail verification is required before you can create an account. For privacy reasons the forums are set up to allow you to hide your e-mail address from other members if you choose.

      7. Post to the forum that is most appropriate for the topic. We realize that sometimes a question can cross multiple topics and it isn't exactly clear where it would be best to post. Please use your discretion wisely. When replying to a topic, make sure that your reply is relevant to the original message (i.e. Stay on topic).

      8. Do not start threads if:

      - There is another active thread on the same topic already in discussion.
      - You are responding to another thread that has been locked/deleted by a staff member.
      - You are asking why a previous thread was locked/deleted by a staff member.
      - You solely want to complain about the behavior of forum participants or content. In doing so, you are only creating another pointless thread.
      - You have already posted the same question/comment in another forum. Do not Double or Triple Post!
      - You want to send a message to a single member... Use a Private Message instead!
      - You are advertising for a business, another association, and forum. - If you want to advertise your products, please contact the site admin via private message.

      9. Do not dig up old threads! If you want to continue a discussion from an old thread (older than 7-8 months), create a new thread and reference the old one in your opening post if necessary. There is very little reason to dig up an old thread.
