It might sound like something out of a science experiment, but did you know you can actually use a potato to generate electricity? While a single potato won’t fully charge your phone, it can definitely produce enough voltage to power small devices or demonstrate how natural energy works — all for free!
How Does a Potato Generate Electricity?
Potatoes contain phosphoric acid, which acts as an electrolyte. When you insert two different metals into the potato (like copper and zinc), a chemical reaction occurs, creating a small electric current. Think of it as a natural battery!
What You’ll Need:
1 large potato (boiled briefly for better conductivity, optional)
1 copper strip or copper coin
1 zinc strip or galvanized nail (zinc-coated)
2 wires with alligator clips
USB charger cable
