When I went to school in Philadelphia, I got a look inside one
of those white things, nothing more complicated than a magnet
in there. We often laughed about the possibilities of buying
a couple dozen magnets from Radio Shack. We could quietly drop 
them into those big shopping bags with handles on them that so
many people carry around in malls. Or, we could just stand in
front of the mall giving away free magnets.

For some unknown reason, we spared mall security the pleasure 
of this experience.
