Mini Low Temperature Stirling Engine Model Heat Education Model Toy Scientific Experiment Props Easy Operation

The operation is simple: pour a cup of hot coffee, put Stirling on the cup, and it will work magically. When it slows down, it means that the coffee temperature is suitable for drinking. It can also work on ice cubes. Some people put Stirling on a glass of hot water, and then put some small ice cubes on the top of Stirling. This makes the temperature difference much larger than normal, and then it runs faster and crazier. The engine model is made of high-quality metal and elegant craftsmanship, which is sturdy and durable. Through hands-on operation, you can observe the whole process of the Stirling engine, understand the working principle of the Stirling engine more intuitively, and deepen students interest in physics.
