Yeah -- I've looked that up also. Strange thing is I remember playing with my etch a sketch with a magnet when I was little. This would have been one of the original ones in the early sixties. I remember it acting as though it was extremely attracted by magnetism. I remember the particles lining up and even being attracted to each other to form "wiskers" around the magnet. Hmmm
I think where they said etch-a-sketch, they might have really meant magna-doodle.
