Demos: 3E-12 Steam Engine

This demonstration uses a miniature steam engine to illuminate a light or blow a whistle. A steam engine works by using a fuel to heat water. The heated water will change to steam. The steam goes into a cylinder and does work on a piston. When the piston is fully extended, a valve opens in the cylinder allowing the steam to escape. By the inertia of the flywheel, the piston is pushed in the opposite direction diminishing the volume of the cylinder. Another valve opens allowing steam to enter and the process continues.
