Broom Finds Its Balance Point

Both fingers meet near the balance point. Ask students to predict what will happen. Balance it on two fingers and slowly move fingers together. Key idea: Friction changes as the support points move, guiding them toward the center of mass. Ask: Where will your fingers meet? Safety and cleanup: Keep broom low and clear of faces. https://www.google.com/search?q=%22Broom%20Finds%20Its%20Balance%20Point%22%20science%20demonstration%20experiment
