Enter the parameters of your homemade water rocket, and launch it! A detailed description of the equations are described at length at the "water rocket equations"
Note that if the initial thrust is not large enough to overcome the pull of gravity, the rocket will simply not launch. This could happen if the pressure is not large enough, the water mass too large or the nozzle too small.
Enter the water rocket parameters, and press "OK, launch!" to simulate it.
