Give a budding mechanic a model engine kit that results in a working, battery-powered four cylinder engine with real lights and sounds. Its clear body lets you watch the spark plugs fire and valves open and close. This Smithsonian Motor-Works Kit includes over 100 parts that easily screw together and detailed instructions to help along the way. The engine recalls many of the machines, motors, and other industrial items found at the National Museum of American History-Behring Center.
The Smithsonian's National Museum of American History, Behring Center, is responsible for the collection, care, and preservation of more than three million objects.
