The main stage was mostly unpressurised. Only used 7mm nozzle on the main stage and I think there were 13mm nozzles on the boosters. This didn't go very high as we were only testing to see if the boosters would separate.

If you go to our main website and have a look at the how-it-works section, it explains the principle and gives you an example of how to build it.

It does provide only minimal thrust. The lowest 2L bottle in the main stage was pressurised, but with 1.5L of water and 0.5L of air and a 7mm nozzle the thrust is pretty minimal. We did this to make sure the rocket had the weight of the water in the bottom for stability tests, but enough air to push it out so it would drain before the rocket landed. Makes for a softer landing that way.

Wow - so the main stage was providing no thrust at all? Pretty impressive loft from just the boosters!
