This engine is driven by the temperature differential between the top and bottom plates. To make temperature differential, simply put it on a cup of hot water or on top of ice. The speed depends on the temperature differential: the higher, the faster. It can reach a speed of 180-200 RPM when in good condition. What's it for:
*Funny gift
*Kids' science project
*Hobby
*Physical/mechanical learning
*Put on your table
*You want to spend money but don't want to spend too much
Features:
