The single visible arc, over 28 video frames is struck and turned off
hundreds of times!! Some arcs last tens of discharges and some hundreds
perhaps thousands! Why? Physics is obviously involved, but offers no
simple answer to the question. There are lots of suggestive thoughts,
but no answers, yet.
