Hexagonal Shape Free-piston Stirling Engine Model Toys with Propeller

The Hexagonal Shape Free-Piston Stirling Engine Model is a fascinating and educational toy that demonstrates the principles of thermodynamics and mechanical engineering. This model features a unique hexagonal design and propellers, offering a technical and intriguing appearance. Through hands-on operation, users can observe the engine's process, understand the principles of Stirling engine operation, and enhance their interest in physics.

Features:

Educational and Engaging: Allows users to observe the Stirling engine's operation, understanding the principles of gas expansion and compression, thereby deepening interest in physics.

Unique Design: Hexagonal shape with propellers, providing a technical and visually appealing look.

High-Quality Materials: Constructed from durable brass and quartz glass for longevity and aesthetic appeal.

Operational Tips:
During operation, the engine model is placed in a horizontal position, and alcohol is injected into the alcohol lamp to ensure the safety of the alcohol lamp. The alcohol lamp heats the piston tube, and the dry air expands to generate power, which drives the propeller to rotate rapidly. Use 95% alcohol (self-prepared)during operation, no water, kerosene, gasoline, lighter oil, liqueur.

Warning:
1, After using it, please let the engine natural cool. Don't touch the alchohol burner, burned tube or the metal to avoid scald.
2, 95% alcohol (self-prepared) should be used in the operation. Water, kerosene, gasoline, lighter oil, and liquor should not be added.
3, The Stirling engine model is suit for people over 14 years old. Operate under adults' supervision.
