Balancing Soda Can

The can balances at an angle. Ask students to predict what will happen. Add a little water and tilt the can onto its lower rim. Key idea: The water shifts the combined center of mass over the support point. Ask: Why does a little water make balancing easier? Safety and cleanup: Use an unsharp, rinsed can or plastic equivalent. https://www.google.com/search?q=%22Balancing%20Soda%20Can%22%20science%20demonstration%20experiment
