What Happens When You Are Struck By Lightning?

Believe it or not, scientists still aren’t exactly sure what causes lightning. The leading theory is that ice crystals, formed inside storm clouds, slam into each other and build up an electrical charge. Lighter, positively charged particles form at the top of the cloud and heavier, negatively charged particles sink to the bottom. When the […]
