I found out about water rocketry actually about five years ago, but I only started to get serious about it now; I bought a Quest water rocket launcher (which broke) and have constructed both a Gardena and standard Clark cable launchers - the gardena works up to 40 PSI or so, and I haven't full-tested the Clark launcher yet. The store where I work sells flavored soda water which has great smooth-sided bottles which I've been using for rockets, just simple one-bottle one stage things for right now and not even fins yet! I was just looking at the FTC tubing at Home Depot today, though...
