Unique Crawler Tank Shape:
The Stirling engine is applied to the model crawler tank to turn it into a toy car that can run.
There's enough power for the Stirling engine model tank to drive, allowing you to observe the magic of operation and energy conversion while you play.
The main body of Stirling engine is made of zinc alloy. The body is made of acrylic. The alcohol lamp mounting bracket is set on the model tank, more safe and reliable.
How to use:
Place the Stirling engine on a horizontal table, then inject 95% alcohol into the alcohol lamp (not more than 2/3), next light the alcohol lamp and place it under the hot cylinder to preheat for 30 seconds, and turn the flywheel on by hand to start. Do not add any water or oil.
Can be used as a teaching aid to understand and learn Stirling engine structure and principles. It can also be used as a popular science educational toy to do scientific and technological experiments, which is a way of training children's abilities and mental capacity. At the same time, due to its superior quality and beautiful appearance, it can also be used as a technological decoration, and can also be as a gift to friends and relatives or children
