DO U KNOW TO CREATE ELECTRICITY FROM A LEMON???

Creating the battery - Insert a penny into a cut on one side of the lemon. Push a galvanized nail into the other side of the lemon. The nail and penny must not touch. This is a single cell of a battery. The zinc nail and the copper penny are called electrodes. The lemon juice is called electrolyte. All batteries have a " +" and "-" terminal. Electric current is a flow of atomic particles called electrons. Certain materials, called conductors, allow electrons to flow through them. Most metals (copper, iron) are good conductors of electricity. Electrons will flow from the "-" electrode of a battery, through a conductor, towards the "+" electrode of a battery. Volts (voltage) is a measure of the force moving the electrons. (High voltage is dangerous!)

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 metals suspended in an acidic solution. Copper and Zinc work well as the metals 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. The lemon: A large, fresh, "juicy" lemon works best. The nail: Galvanized nails are coated in zinc. I used a 2" galvanized common nail. The penny: Any copper coin will work. (Canadian pennies from 1960 - 2001 all worked)

yes i know. use copper cathode and znic anode , which are to be inserted in the lemon ; its juice acts as the electrolyte.
