FlipFact of the Day: Contrary to popular belief, lightning strikes twice in the same place. In fact, this happens more often than we think.
According to a recent study, the negative charges inside a thundercloud aren’t actually discharged all at once.

These needles may be as long as a hundred meters, but have a diameter of less than five meters. Thus, they are too small and short-lived for other lightning detection systems to spot.
