HMANE Mini Vertical Flywheel Stirling Engine Model - Adjustable Speed Educational Science Toy | ENJOMOR Physics Learning Kit | Perfect Gift for Engineers & Students | STEM Classroom Demonstration & Home Decoration

The Stirling engine: A simple but elegant demonstration of converting heat into mechanical motion, is built with a knob on the top which is capable of adjusting the imported air volume to control the rotational speed of the engine for a convenient and incredible observation to piston movement.

Delicately Manufacturing Technology: Mainly made of metal, the engine is designed with an exquisite and magnificent golden appearance featuring excellent color fast and rust prevention performance. Combining texture with beauty, the durable machine runs smoothly and reliably due to the heatproof and durable stainless steel heating tube and wear resistant piston that can run for a long time.

Wide Applications: The Stirling engine is a closed-cycle reciprocating engine in which the gas is compressed and expanded periodically at different temperatures by external heating, available as a physics/mechanical teaching demonstration, an ideal experiment teaching aid in the laboratory, an impressive gift&display, a stunning desktop decoration, etc.

Educational Toy: For an external combustion engine, the Stirling engine runs steadily and fast only by heating the alcohol lamp and spinning the flywheel, which is so amazing that makes a cheerful and imaginative desktop technology toy.

Superb & Creative Gift: The astounding mechanical craft, with superior visual texture and aesthetic appearance, is perfect for children and technology lovers being a creative and impressive gift for friends, families, teachers and students on birthday and Christmas.
