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.

I'm asking 'Santa' for a few cases of Clear American 1Liter bottles, and a few boxes of .22LR Bullets. It doesn't take much to keep me happy. Merry Christmas!

Merry Christmas to you too! What do you mean by a few cases of plastic soda bottles. How many are in a case? And I thought you used two liter bottles for rockets. XT1 :2011D:

Happy new year! 2014!

The Clear American 1L bottles come in a case of 12. They burst at around ~160PSI and are available at Wal-mart. I haven't used 2-Liter bottles for a few years now.

Oh I see you must go to one of those Super Wal-Mart. They don't sell those her but they do sell them individually for like 0.59$ at giant and like .79$. I like them better for reasons such as less drag, thinner rockets, ability to make short rockets that aren't fat, and like the higher burst pressures.

The hard part is finding bottles with long straight sides, so you can make the rocket with less segments. It's good to find ones with stubby necks and not long tapered necks, because the tapered part is not useful.
