For years I've used them to reflect light inside a machine to read legends
on cards and such.
I've got flashlights, but theres never one when you need it...

I just noticed that sunlight reflecting off the top
side of a CD focuses
somewhat, maybe with a focal length of about 20 feet. Off of the data
side, it spreads. I've tried it with several different types, and so far
they all show the same effect. Would anyone care to explain why?
