What Is Ball Lighting?

Ball lighting is one of the most mysterious forms of lighting and is a comparatively rare phenomenon. It is also known as globe lighting and occurs during periods of intense electrical activity in the atmosphere. It can penetrate closed glass windows, is usually accompanied by a hissing sound but is not destructive. They are said to be plasma which is a totally ionized state of matter, is at a very high temperature and in which both positive and negative ions move about in a random manner. The behavior of these balls of lighting have not been satisfactorily explained so far as they have not been reproduced in a laboratory so far.
