Water Rocket Forum

I was just at our local Home Depot earlier today looking for water rocket stuff and came across a set of Melnor "Quick Connect" hose connectors - U.S. "Gardena" connectors, but here's the cool thing: it's a 4 piece set with one each male and female nozzles and connectors, and the female nozzle actually fits on a soda bottle - no modification needed! (The threads aren't an exact match and I had to mangle my Dr. Pepper bottle to get it back off, but teflon thread tape should help.) The set was something like $4 and change.

Sorry if this is old news, but I think it's a pretty neat find.
