Hot Water Rockets
A hot water rocket (or steam rocket) is a water rocket which uses hot blast water as its propellant. Water is kept in the rocket under pressure, at below its boiling point at that pressure. As it exits through a rocket nozzle, the pressure drops and the water instantly boils and expands against the nozzle and this greatly increases the exhaust speed and thrust.
The idea of such rockets was conceived by Germany before the Second World War, with the suggested use of an alternative rocket engine for launching fighter jets.
