Water Rocket Construction

Main Rocket Page Home Page

These bottles will hold at least 120 PSI (8 bar) of pressure. I've only launched it at 6 bar due to lack of an adequate pump (and I don't have a remote launcher yet - see below), but even at that I have trouble finding a park big enough to be safe - an Australian football field is huge by the standards of other football codes, but isn't big enough if the rocket is even slightly unstable at launch - I've had to walk a long way to retrieve it sometimes!

See also Mal Goris's pages, where he describes his development of my launcher with detailed photos and diagrams.

Quick-connect end

That's the metal part of an old car tyre valve, threaded and soldered into a brass end-cap. I need to add a pressure gauge to this soon.
