Product Review

Driven by the little lamp, this engine will rotate at speed around 1700-2000 RPM. It's assembled and will run within 5 minutes after opening the package provided you have a bottle of alcohol by your side.

It is a MINI version which can be put into your pocket. A little bit smaller than a 330ml Coca-Cola can. But do not be confused by its size, its quality and performance are very good! We've done special treatment to the machine to avoid rusting and fading; use heat treated high grade spring steel stand to ensure its stability; employ thickened quartz glass cylinder and bearing steel rod to strengthen its robustness; specially designed Lever Mechanism and Crank-rocker Mechanism makes it more "mechanical". It will definitely be a great gift to those with mechanical brains. A great desktop toy for everyone.

It's also a perfect teaching tool demonstrating the process of energy exchange: the hot air in the sealed cylinder enables power piston to move continuously, and flywheel will spin at the same time; periodical air expansion and contraction makes heat energy converted to mechanical energy... Kids will be excited and curious about why. This will enlighten them to explore the world.
