For every action, there is an equal but opposite reaction.
It you blow up a balloon and don't tie the end, the air inside the balloon is pushing against all of the balloon equally. When the untied end is released, air pushing out the back causes an equal affect of pushing on the front and the balloon moves forward.
Rockets work in the same manner. Instead of air, they use combustible fuel for their force.

The body of a rocket needs to be long because it helps with the propulsion of the object. It is strictly to help with aerodynamics.
If you count the rocket propulsion developed by cephalopods, rockets have existed since the Silurian period.
The term 'rocket' is very General, the first recorded flying object to take off using rocket propulsion was either the Me-163 or the V-1 Doodlebug, both made in Nazi Germany.
Rocket Propulsion Test Complex was created in 1965.

the red rocket is used to rub for a splash of white fun. All other rocket engines are used for propulsion to gain lift.
