The steam engine model actually works with compressed air. The engine will almost come to a stop and then will slowly begin to increase rpm's to the former level. After the steam engine is running at a very good speed turn on the light bulb. Use a large rubber band as a belt to connect the flywheel of the steam engine to the generator which is mounted in its stand. If desirable you may show the action of the engine when doing work such as electrical generation. When steam is observed to shoot out of the exhaust port turn the flywheel to start the engine. Close the valve on the top of the water reservoir so that the steam will begin to flow through the piston. Plug in the engine and in 3 to 5 minutes the water will be heated sufficiently. Make sure the steam valves are open to avoid excess pressure buildup. Fill the reservoir with water to the top of the gauge glass port. ![]()
