How does a Fruity Battery work?

A fruity battery works by using the acidic juices in fruits, such as lemons or Oranges, to facilitate a chemical reaction between two different metals, typically a copper and a zinc electrode. The fruit acts as an electrolyte, allowing ions to flow between the electrodes, generating a small electric current. This process converts the chemical energy stored in the fruit into electrical energy, demonstrating the principles of electrochemistry in a simple and educational way.
