To operate the engine, simply pour a cup of hot coffee and place the stirling engine on top. As the engine slows down, the coffee temperature becomes suitable for drinking. It can also be used on top of ice cubes, where the greater temperature difference makes the engine run even faster and more excitingly.

The stirling engine comes equipped with a multicolor LED that you can install yourself. The heat from the high-grade alcohol fuel causes the engine to run madly, generating electricity that powers the LED, creating a mesmerizing lighting display.

To start the engine, fill the alcohol burner with 95% alcohol (recommended fuel) and light it. Let the flame heat the cylinder for 60-120 seconds, then give the wheel a gentle push, and the engine will run like a charm.

These stirling engines make for amazing conversation pieces on your desk. Watching people's reactions as you start the engine on a cup of hot water is an ice-breaking success. It's a marvelous toy that captivates and intrigues all who see it in action.
