A coin battery is similar to fruit battery experiments, except that the fruit's part is replaced by a small amount of salt water. It's an easy science project to do, especially if a project like the lemon battery has already been performed.
Materials
- A small glass or bowl
- Salt
- vinegar
- Spoon or stir stick
- Thick paper towel, blotter paper or even cloth
- Scissors
- About 10 each, aluminum coin and copper-zinc alloy coin
- A voltmeter that can read at least tenths of a volt
- Small battery, AA or AAA is fine
- Optional LED
