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.

real stories of scuba tank explosions !!!

In this site it shows a scuba tank that exploded and amputated a hand.
90% of the explosions happens in the refiling.

Australia: THE South West Rocks community is in shock after a well-known dive master was seriously injured by an exploding scuba tank.

Murray Amor, 62, lost his right hand and suffered serious injuries to his right leg when the tank exploded at the South West Rocks Dive Centre about 3.40pm on Sunday.

Mr Amor is the equipment service manager at the centre and was doing a routine refill of some scuba tanks when one blew up.

Police believe the tank Mr Amor was filling ruptured and blew into several pieces, tearing large gouges in the brick walls of the building.

Mr Amor was rushed to Kempsey Hospital and later airlifted to Sydney, where he was believed to be in a stable condition yesterday.

South West Rocks Dive Centre owner Peter Hitchins said Mr Amor was doing as well as could be expected under the circumstances.

“He’s in good hands,” Mr Hitchins said.

“He’s conscious and having a joke. Obviously now we’re all hoping for a speedy recovery.

“We’re all in shock.”

Mr Hitchins said he would wait until the police investigation had concluded before making a comment on what had caused the explosion.

On the centre’s website Mr Amor is described as an experienced skipper and dive master.

Rough handling, miss-use, corrosion and many other factors can critically effect the strength and integrity its construction. The end result is an explosion, that usually occurs during refilling, killing the compressor operator and destroying the dive shop.

In 2003, a dive instructor working at Koh Tao, Thailand suffered critical injury when a scuba tank pillar valve plus the removal clamp was jettisoned through his leg during a servicing action; the aluminium tank went through a few concrete walls off into the jungle. A well-trained-medic saved the dive instructors life.
