  2. 3. Wrap one end of each wire to the leads coming off the LED. 4. Wrap the other end of one of the wires around the nail. • 1 lemon • a galvanized zinc nail • 2 pieces of copper wire • an LED • a copper coin You need: To do: 1. Place the sharp end of the nail into the lemon. 5. Touch the end of the other wire to thecoin. 2. Make a 1 cm cut in the lemon and insert the copper coin halfway into the lemon. If a copper coin is not available, just insert one end of the copper wire. What happens: The LED lights up. But why? The lemon does not really store electricity. Instead, a chemical reaction between the zinc nail and the lemon’s juice takes place. This reaction releases two electrons from the zinc atoms. The electrons flow, making electricity that lights the LED. See a lemon battery set a world record. Diagram: START-UP MEDIA PVT LTD @engagelearningmag
