Seeing how we have covered large capacitors,  frequency shifting, etc.,
how about something really interesting.

What is the speed of dark?  This came up in an experiment when we were
fooling around with illumination.  Given a light, and a room, how long
did it take to become "illuminated?"  I was describing the problem to
my experimental animals, and then one of the kids said, "Yeah, that's
the speed of light, but what's the speed of DARK?"  One then pulled out
a Garfield cartoon, where the same question was asked.  O.K.- What is
the speed of DARK?
