A water rocket is a type of model rocket using water as its reaction mass. The water is forced out by a pressurized gas, typically compressed air. Like all rocket engines, it operates on the principle of Newton's third law of motion. Water rocket hobbyists typically use one or more plastic soft drink bottles as the rocket's pressure vessel. A ...

In many home made versions, the bladder is a recycled drinks bottle, from which air is released rapidly by the user jumping, or 'stomping' on the bottle - hence "stomp rocket".

On October 16, 2015, Delft Aerospace Rocket Engineering (DARE) launched the Stratos II+ rocket from El Arenosillo, in Spain, to an altitude of 21.457 km with a successful water landing and capsule recovery. This broke the original amateur European altitude record of 12.3 km set by DARE in 2009 with the launch of Stratos I.

The early Mysorean rockets and their successor British Congreve rockets [59] reduced veer somewhat by attaching a long stick to the end of a rocket (similar to modern bottle rockets) to make it harder for the rocket to change course. The largest of the Congreve rockets was the 32-pound (14.5 kg) Carcass, which had a 15-foot (4.6 m) stick.
A smaller variation is the gyrojet, a small arms rocket launcher with ammunition slightly larger than that of a .45-caliber pistol. Recoilless rifles are sometimes confused with rocket launchers. A recoilless rifle launches its projectile using an explosive powder charge, not a rocket engine, though some such systems have sustainer rocket motors.
