NASA provides a quaint description of how the Hero's engine is a form of propulsion here: [[ http://history.msfc.nasa.gov/rocketry/02.html | http://history.msfc.nasa.gov/rocketry/02.html]]   
This is a video of the demo: [[ http://www.youtube.com/watch?v=Drk43G9s4tU | http://www.youtube.com/watch?v=Drk43G9s4tU]]  


**Not currently functional. Bearing needs replacement?**


===== Purpose =====


A demonstration of torque and angular acceleration that is also an example of the conversion of heat to kinetic energy.  



===== Apparatus =====


Hero's Engine, Bunsen burner (or a heat gun) and stand.  



===== Setup =====


1. Heat water in the bulb using a Bunsen burner. 
2. When steam begins to jet, the engine will rotate.
