Yesterday, we had the joy of using something not for its intended purpose. A few years ago, my mother bought me the little magnets you put on necklaces so that you don’t have to mess with the clasp. They are rare earth magnets and work fabulously (especially since I have acrylic nails).
We removed the charm from a necklace, wrapped the chain around a twist tie for better control, and dropped the magnet into the headlight housing on our car to recover a dropped headlight. Success! Now if only we could actually figure out which headlight we need to replace.
