We also compared the thrust produced by stretching alone to the thrust a regular rocket produces.

Measuring Bottle Stretch Thrust
Last weekend we did a little experiment to measure the thrust produced as a bottle contracts while depressurising. From earlier experiments we learned that bottles can stretch significantly and we wanted to know how much of this energy is returned during the boost phase. The main idea behind this experiment was to help refine future models of water rocket thrust behaviour. The full experiment writeup is here:

Keep up the good work George your a credit to the water rocket world
kind regards Team BWR
Thanks Dan :)
Good job George, it will really help in making new reinforecements, so we don't lose this significant amount of energy for the rocket... Just need to find a way to do it...
I enjoy your site very much. I'm looking for a forum that I can add my idea to. I've made a water rocket thruster that causes the water to leave the rocket in a vortex causing the rocket to spin like a rifle bullet without needing to angle the fins. If you interested please contact me at rlwilson39@gmail.com.
