Did you know that potatoes can create a battery that could light your room for more than a month? Haim Rabinovitch, a professor of agriculture, recently tried an experiment with a raw potato to see if it can conduct electricity. He put raw potato slices between copper and zinc cathodes connected with a wire, and discovered that a single raw potato could light a room for about 40 days!

This is a very useful solution for different parts of third world countries which don’t have electricity constantly. Dr. Rabinovitch’s amazing discovery gives these people new opportunities by using a neat trick with a simple ingredient.

If you’re wondering why he chose potatoes, the answer is simple – they can grow anywhere and are easily available in the whole world. Watch the video below to learn more about the experiment:
