How do You Make a Battery?

You can make a battery from a lemon or a potato! When using a potato you need steel (a paper clip will do). Now get some copper wire, a dc voltmeter and you’re in business! Insert the steel into one end of the potato and copper in the other. clip the meters negative probe on the steel and the positive on the copper. Together, the steel, copper and potato create a chemical action which in turn creates voltage!
