Gatling Gun on Stirling engine

Gatling Gun on Stirling engine  Made of metal material, stable and durable. High speed and long service life without wear. The alcohol lamp is fixed with screws, reliable and safe.Exquisite appearance: Gatling gun shape. The engine has a total of six cylinders that rotate when starting, like a real cannon.  Easy operation: For safety reasons, light the alcohol lamp. The alcohol lamp heats the piston tube, and the dry burning air expands to generate energy, makes the flywheel rotate quickly, thereby lighting the bulb (95% alcohol should be used when working (not included), Do not use water, kerosene, gasoline, lighter oil, liquor, etc. Educational value: By controlling the engine, children will observe and know the workflow and more intuitively understand the principle of operation of the Stirling engine, deepening their interest in physics. Wide application: It has a wide range of applications, such as a great gift for a children's science project, physical/mechanical training, a teach
