Ball Lightning is a rare event that happens in the sky. But unlike a regular lightning that appears as branched lines. Ball Lightning is a glowing ball of light which can be as small as a marble or as large as a gas balloon. What makes it more intriguing is the fact that it lasts much longer and even explodes eventually. The people who have seen a Ball Lightning say that it has a mind of its own and exhibits strange behaviour. Some have seen it passing through objects and move according to any pattern in the vicinity or stopping at an obstacle, etc.
