I’m not sure what you are saying here. The force pushes against the nozzle, (and of course the walls of the combustion chamber.) That is the purpose of the rocket engine, to push the rocket forward. They are not just there to provide mood-lights.

I said "nozzle", as in the side walls of the engine.

The force doesn't transfer via those walls, rather it goes through the full tank of the rocket and pushes against the top.

Ok? I seem to have said the same.

Where do you think the force starts on a rocket? What pushes the rocket forward?
