STARPOWER Low Temperature Stirling Engine Motor Model Steam Heat Experiment Educational Toy Fully Assembled

Features:
A Stirling engine is a heat engine that operates by cyclic compression and expansion of air at different temperatures, such that there is a net conversion of heat energy to mechanical work.
Usage: Place the model on a cup of hot water, gently flip the flywheel until the machine can run freely itself.
Transparent cylinder and piston, make it straightforward for you to observe the movement. Help student to better understand this physics theory.
Fully assembled metal body, easy to use. You can dismount it to practice your operational ability if needed.
Safe for children, no need to fire alcohol burner.
