“They kind of exist at the spiritual center of our lives, really,” says Dave Kapell of refrigerator magnets. And he should know. The Minneapolis-based musician-slash-inventor is the founder of Magnetic Poetry, which has sold over three million kits (that’s more than a billion word tiles) worldwide. Faith Salie chatted up Kapell and more magnet magnates–including Louise Greenfarb, who made the Guinness Book of Records for owning the most refrigerator magnets in the world (45,000, but who’s counting?)–for this recent CBS Sunday Morning segment, which concludes by considering the bane of magnet lovers everywhere: the stainless steel fridge.
