        Designing Electric Circuits: Steadiness Tester

        Electric circuits have been used in an unfathomable number of creative inventions, some more useful than others. In this video segment adapted from ZOOM, cast members create and then test each other's nerves with a device they call a steadiness tester. They use a variety of materials that make good conductors, including aluminum foil and a coat hanger, and find out how difficult it can be to keep from completing an electric circuit.
