Hot Air Stirling Engine

The Hot Air Stirling Engine is a heat engine that operates by cyclic compression when exposed to different temperatures. You can put it on top of your cup of tea or cold ice tea and, if temperature difference between air and engine base is at least 20°C (68°F), it will start spinning. This engine is great to encourage kids interest in science.
