Creating a battery from a lemon is a common project in many
science text books. Successfully creating one of these devices is not easy.
Batteries consist of two different ********ls suspended in an acidic solution. Copper and Zinc work well as the ********ls and the citric acid content of a lemon will provide the acidic solution.
Batteries like this will not be able to run a motor or energize most light bulbs. It is possible to produce a dim glow from an LED.
