Inflate a balloon and let it go. The air will rush out and the balloon will shoot of in the other direction. Here the surface tension of the balloon exerts an elastic force on the air inside, the reaction force is the air pushing against the rubber.
This basically is what rockets do. You heat a gas (by explosion) and the increased pressure force of the gas pushes the rocket up. The rocket in turn pushes the gas out.

Fill balloon with air. Hold the opening closed. Then let go. As the air shoots out of the balloon, the balloon moves in the opposite direction. The air is like the thrust from a rocket
