Replace your wall clock battery with a banana peel! You don’t need to buy batteries anymore.

To make a simple wall clock battery using banana peels, first, choose a banana that is ripe enough. Bananas contain potassium compounds that can serve as electrolytes in batteries. Next, carefully peel the banana peel to separate the inside. Cut the banana peel into small pieces to make it easier to process. Afterward, soak the banana peel pieces in a salt or vinegar solution to improve their conductivity. Next, prepare two different types of metals, such as copper and zinc, as electrodes. Attach the electrodes to the soaked banana peels. Make sure that the electrodes do not touch each other. Then, connect the wires from the electrodes to a simple wall clock as a load. This process creates a redox reaction between the metal and the compounds in the banana peel, generating enough electricity to power the wall clock. Although this battery is simple, the concept shows that natural materials such as banana peels can be utilized to obtain a simple source of energy. Replace your wall clock battery wit
