Bored or feeling like a laugh in the workshop
Check out this mad site http://www.spagweb.com/magicspanner/water_rocket/index.htm
Did this for my physics A-level coursework.
0-200MPH in 0.2 seconds
i like the way it says 'safeish' way. not totally safe, but not far off
I promise it's not in the least bit safe.
If you launched it while leaning over it I'm sure it would smash your face in/off/up. I guy from Japan once straped about 6 to his back and they
him 30+ feet into the air. Got a video of it somewhere.
And I'll let you guess what the results of a 50Mph terminal velcoity landing would do if it hit you on the head on the way back down.
The director of the 6th form I was at wasn't too impressed with a few close calls involving his car roof and my rocket
