Rocket engine nozzle
A rocket engine nozzle is a nozzle used in a rocket engine to make the burning propellants go out faster and over a bigger area.
Nozzle shape
The difference between the skinniest part of the nozzle to where the burning fuel comes out is what makes the rocket work so well. The shape of the nozzle is important too, with the best nozzle angle being about 15 degrees, and a smooth angle for the nozzle.

Diagram of a de Laval nozzle, showing flow velocity (v) increasing in the direction of flow, with decreases in temperature (t) and pressure (p). The Mach number (M) increases from subsonic, to sonic at the throat, to supersonic.
