Ball lightning is a mysterious phenomena that’s been seen since the beginning of recorded history, but it’s so rare most people put it in the category of folklore or pseudoscience. However, there’s some new studies that seem to show that ball lightning is not only real, but there’s possibly many different kinds, and there’s a lot we can learn from it.

My dad claimed to have witnessed ball lightning during a storm in New York when he was a child. The whole family watched, horrified, as the softball-sized ball of plasma entered through a wall, floated lazily through the room, and exited through another wall.
