CyberKnet writes "I have an extensive music collection on original CD media. While most of it is in impeccable condition, I have a few discs that have suffered extensive scratching through listening to the disc either via a portable disc player, or in a car CD stacker. I've long since learned the error of my old ways and don't listen to discs in those devices any more, but those discs are irreplaceable in many cases. I would very much like to be able to repair them or have them repaired to original condition, or at least well enough that I can pull the tracks off once and archive the track data. I have heard really uncomplimentary things about devices like the Skip Doctor; ranging from it not helping to it making things worse. I've heard great things about JFJ devices that are seen on the counters of most Hollywood and BlockBuster video stores, but even their consumer devices start at $250. I would appreciate any other suggestions for devices that people have had personal experience with that won't break the bank."
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
