Two-Potato Clock
Watch this clock run on two potatoes! It's educational, it's fun and it runs on just about anything! The natural ingredients found in common household items are used to conduct low voltage electrical output between bi-metal probes. There are no batteries required. Answer the questions: "How does a potato make electricity?" and "What are those metal probes made of?".
