The lemon battery is one of the most popular science experiments for kids. It features in Episode 2: B is for Battery of Circuit Playground by LadyAda from AdaFruit Industries. When my kids watched this episode they of course wanted to make a lemon battery.
It’s a quick and fun experiment to do and kids can get really involved with it. When their cousin visited we had fun doing the experiment. We used a mixture of lemons and limes – any acidic citrus fruit will work nicely.
