 ===== Description =====
-Simple heat engine
+Stored in a small box with the branding 'Thermobile' on it. A plastic chassis connects two wheels, one bigger one made of plastic and a smaller one made of brass. Around them is a loop of nitinol- a shape memory alloy- that has been 'trained' to straighten when heated up.
 ===== Purpose =====
+Illustrate another example of the huge variety of heat engines. Demonstrate the action of a much simpler heat engine, and show what unites all heat engines: a heat differential.
