How do rockerts work?
At the center of every rocket is a device called the combustion chamber. Here rocket fuel is mixed and ignited into a controlled explosion. The explosion produces a pressure on the walls of the chamber. There is only one (external) opening to the chamber which opens to the rear of the rocket. Through this opening the exploded products escape, because of this there is no force exerted by the wall of the chamber against the explosion. This means that there is an unopposed force on the opposite end of the chamber - the force that moves the rocket 'forwards'.
