Tripropellant rocket

A tripropellant rocket is a type of rocket with three different substances (called propellants) in it to help it move. The three different propellants are burned in a special process to create a lot of heat and pressure, which then propels the rocket up in the air. The three propellants used in this type of rocket are usually hydrogen, oxygen, and nitrous oxide. The combination of these three chemicals creates a powerful force that can move the rocket very quickly.
