describe:

-Exquisite appearance: the car has a realistic shape, with both beauty and texture

-The overall polishing is meticulous, the color is bright, it is not easy to rust and fade, and it has a high-end texture. Groove fixed alcohol lamp, safer and more reliable

-Operation method: Place the model in a horizontal position during operation, pour alcohol into the alcohol lamp to ensure safety, and light the alcohol lamp. After preheating for 1 to 2 minutes, the alcohol lamp heats the piston tube, the dry air expands to generate power, and the car starts to move forward. (Use 95% alcohol, bring your own)

-Through hands-on operation, you can observe the entire Stirling engine running process, understand the Stirling principle more intuitively, and deepen your interest in physics learning.

-The product itself has been assembled and can be used directly. Its excellent quality and exquisite appearance also make it have a high collection value and can be used as a high-end gift.
