Some years ago, a friend got hold of a number of memory boards with the chips
soldered in; he didn't want the boards, only the chips. He would hold the
board by the corner, with pliers, and wave it around, about an inch above the
flame of his kitchen stove. When the solder got shiny (melted), he'd rotate
his wrist to place the chip side down, and rap the board on the edge of the
stove - hey, presto! all the chips would fall on the floor. Oddly, though, his
wife wasn't too fond of the metallic look the solder splats gave to the vinyl
flooring...
