Light Your Room for a Whole Month by Using a Potato!!!

During a power outage, or when you need to brighten a dark area of your home, you can use a potato and light bulb with a few other elements to create light. Your car battery uses chemical reactions in an acid bath to create electricity. When you put copper and zinc electrodes in a potato, phosphoric acid in the potato reacts with the electrodes to generate electricity needed to light the bulb. While a potato-powered light bulb won't generate much light for a long period of time, it's enough to gently brighten a dark area while waiting for the lights to come back on. Watch the video
