Why is ball lightning a strange electrical phenomenon in nature?

     Ball lightning is an unexplained natural phenomenon that happens very rarely. It appears as a glowing ball during thunderstorms, following a lightning strike. It is said that these fireballs shine too brightly, and can be white, blue, yellow, orange, or red in colour. They vary in size and form; from that of a pea, to the size of a small bus.

      Accounts of ball lightning have been recorded for the past few centuries. According to witnesses, these fireballs move in an unpredictable and fast manner, followed by smoke that forms spirals around them. Believe it or not, they can even enter buildings through doorways or windows, travel down corridors, and even navigate their way to certain points. They make hissing noises and sometimes, loud ones too. And all of a sudden, they disappear.

      The reason behind the formation of ball lightning is unknown, and there are many theories talking about the same. Even though there are many explanations for this phenomenon, none is accepted widely.
