Coat-Hanger Bell Through String

A quiet tap sounds like a huge bell through the strings. Ask students to predict what will happen. Tie strings to hanger, place fingers near ears, and gently tap hanger. Key idea: Vibrations travel efficiently through the solid string to the ears. Ask: Why is it louder through the string? Safety and cleanup: Teacher demonstrates placement; no string wrapping. https://www.google.com/search?q=%22Coat-Hanger%20Bell%20Through%20String%22%20science%20demonstration%20experiment
