Re: An embarrassing post
In a pressurized, closed container, air pushes on the inside surfaces of the container. If you put a hole in the side, air no longer pushes on the missing area (the hole), so there is an imbalance of forces. This pushes the container (rocket) in the direction opposite that of the hole (nozzle) out of which gas is escaping. The rocket pushes against itself!

If we think of them as separate, then the fuel and the rocket push against each other.
