RVFM Hero's Engine

Hero's Engine demonstrates the principle of jet propulsion. The apparatus consists of a small Erlenmeyer flask with a rubber stopper and two tubes with tangentially oriented jets. A collar is provided around the flask to hang it above a heating source. When the water boils inside the flask, steam escapes through the jets and the flask spins.
