Video Description

In less than the blink of an eye, a single lightning bolt can unleash power six times hotter than the surface of the sun. Despite being one of nature's most frequent and destructive phenomena, occurring up to 8 million times daily, it is also one of the least understood. The documentary delves into the mystery of what sparks a lightning bolt, from the role of cosmic rays to the bizarre and captivating world of its after-effects—including mysterious "sprites" and "elves" that dance above storm clouds, as well as the elusive "ball lightning".
