I`m doing a science project. I`m made a battery out of 2 wires with stripped wires, copper coins, tape, a sauser, paper towels, scissors, aluminum foil, warm salty water, and earphones. I exchange the copper coins for different metals such as nickles. I know the copper coins work best but I don`t know why. Can you help me?
