Did you know that you can get electricity out of a lemon? Well, you also need a zinc coated nail and copper wire. Lemons have a strong sour taste, because they have citric acid in them. The acid in the lemon reacts with the nail, and makes electricity flow from the nail to the copper. Take a look at the zinc after awhile, it changes color because of a chemical reaction. Why don’t we just tape lemons to our cellphones? Silly question. But, did you ever wonder who made the first battery and what life would be like without them? Batteries gives electricity because of chemical reactions like the lemon battery. A man named Alessandro Volta made the first battery 316 years ago, and they has been getting better ever since. Today, we love our batteries and need them for our toys? What do you think will replace batteries in the future?
