Adjustable Speed Stirling Engine Model Science Experiment Stem Toy with Ball Bearing Flywheel - Red
Features:
.This Stirling engine model is novel and unique, with a sophisticated wooden base. .The amount of air conduction can be adjustable with top knob to control the speed of Stirling engine, which is easy to observe the dynamics of the psiton .The main parts are made of aluminum alloy and brass, which are sturdy and durable. The heating cylinder is made of quartz glass, featuring low expansion coefficient and high temperature resistance. .Fuel: 95% alcohol (not included) should be prepared. Can not add water, kerosene, gasoline, lighter oil, liquor, etc. .Starting Method: Place the Stirling engine model on a horizontal table, add two-thirds of 95% alcohol to the alcohol lamp, ignite and heat for 30 seconds, then turn the flywheel, and the engine can run. .Working Principle: The Stirling engine outputs power through a cycle of cooling, compression, heat absorption, and expansion of the air in the cylinder. .Significance: Through hands-on operation, you can observe the operation process of the entire engine, understand the working principle of the Stirling engine more intuitively, and deepen your interest in learning physics. .Gift: It can be used as a high-end desktop decoration due to its superior quality and exquisite appearance, can also be used as an exquisite gift to your friends, family and others. .For Crowd: 14+
