STARPOWER Vaccum Stirling Engine Motor Model Experiment Educational Toy

Features: Principle: engine uses the inertia of the flywheel to drive the piston to move, which will lower the air pressure inside the cylinder. And the is sucked into the cylinder and burned, and the valve is closed. At this time, a state generates a negative pressure, and the negative pressure causes the piston to continue to move to maintain the cycle. Fully assembled, easy to use: Fire the, continue to flip the flywheel until the machine can run itself. No need to add water. This model can clearly show the movement of valve and piston, helping students to deeply understand the internal and external combustion engines. Ideal model for experimental teaching and researching. Fine polished stainless steel body, solid wood base, fine copper, all metal hot gas cylinder &, wick - materials combine into a delicate & durable model. Nice choice as a gift.
