Features:

LTD Stirling Engine: The dreamlike intelligent engine is primarily made of metal, giving it a metallic luster and an exquisite appearance.

Simple Operation: Place the engine model on a water cup or coffee cup with water temperature above 90 degrees Celsius. After half a minute of preheating, the undulating flywheel will magically run. This engine serves as a delightful desktop toy.

Durable, Continuous Operation: The engine is durable and operates silently. With a sufficient temperature difference, it can continue running, making it an excellent display for your desktop or office table.

Multiple Uses: This cost-effective and interesting product is ideal for scientific experiment projects, energy conversion and dynamics studies, and teaching demonstrations. It is an amazing toy that can spark conversations with friends as everyone wonders how it works.

Perfect Gift: The engine model is a perfect surprise gift for birthdays and Christmas for friends, family, parents, or children. It is an exquisite toy for mechanical enthusiasts, model collectors, and a superb teaching tool favored by school teachers. Suitable for ages 8+.

Note: If there is mechanical noise, use a little graphite for lubrication to make the engine quieter. You can scrape graphite from a pencil with a knife. Do not add oil for lubrication, as oil will mix with dust to become a pollutant, increasing friction and preventing the Stirling engine from functioning properly.
