I launch a proprietary 'Rokit' 2-litre-bottle water rocket. A cardboard tube was taped to the bottle to accommodate the supporting launching stick. Also a tennis ball was taped to the end of the bottle to improve stability and cause the rocket to reach a greater height. Release pressure was approximately 40 pounds per square inch. Notice the cloud of spray as the pressurised air inside the bottle punches out past the remaining water.
