Hero's Engine

The video tutorial explains how movement can occur without external forces, using an experiment with an aluminium water bottle, boiling water, and a Bunsen burner. The setup involves drilling angled holes in the bottle, allowing steam to escape and cause rotation due to Newton's third law. This principle is similar to how rockets operate in space, where the expulsion of gases results in forward propulsion.

What is the effect of the steam jets on the bottle's movement?

How does the experiment illustrate the concept of torque?

In what way does the experiment relate to how rockets work in space?
