Test Fluid Tank

I need a tank for a project of mine. I needed something to cap the pressure, so I added a water rocket. It is completely automated so sit back and enjoy. The rocket takes off when the fluid "boils" because it increases the pressure enough to set it off. You can remove the one time toggler and adjust the dampers to set how much liquid can be in the tank at a time. Please tell me if you need help with this or if you have any suggestions for builds with fluids.. Thanks sdac for the best part of Principia, fluid. 3 likes and i will add derivatives
