Details:

 

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 around 220-250 RPM when in good condition.

This product complies with the applicable regulations and standards under CPSIA and any other acts enforced by CPSC. It passed ASTM-F963 Standard Customer Safety Specification For Toy Safety Toxic Elements Test/Flammability Test/Physical and Mechanical Test.

Please note that we detached the flywheel from the stand to ensure its safety while shipping. It is easy to put it back.
