It s like you re a thunderstorm and your movement creates electricity. Scientists believe that as a thunderstorm moves over the land, the air around and in and under the storm goes bumping and swirling around. This movement causes the positive ions and negative electrons to build up to great levels. The lightning flash may go from cloud to cloud around the storm. It may flash up inside the storm.
Lightning can start at the base of the cloud and go down to the ground.
And, it can start at the ground and go up to the cloud. Lightning safety is simple - when you see lightning or hear thunder, you need to go inside a sturdy house or building, or even get into your car. Don t take shelter in metal tool sheds, picnic shelters, or temporary concession stands at ballparks. Get away from tall objects like trees or poles. Your hair may stand on end, or you skin may tingle.
