Behold the amazing power of nature in this Nova program. This video contains an interesting -- and at some points exhilarating -- study into the source of lightning. The program ends with an electrifying light show set to music. Quite a display. Perfect for anyone who can't seem to drag themselves off the front porch as they see a dangerous yet breathtakingly-beautiful thunderstorm fast approaching.
