This is video from Dayton, Ohio of a man filming a recent wind and hail storm when he inadvertently captures an arc of blue ionized energy traveling down a powerline. How exciting. I didn't read the video description at first and just assumed they were police car lights, and was left wondering why this was a video anyone would bother uploading to Youtube, before I remembered the other 99/100ths of videos on Youtube.
Keep going for the video while I shuffle across the carpet in my socks and try to shock a coworker.
Thanks to MSA, who's convinced it was an alien visitation, which I also haven't ruled out.
