Will my magnet stick to ...... ?

Bad news for tuba players. Magnets do not cling to brass, stainless steel, aluminum, copper or tin -- so you cannot display them on your trombone, stainless steel fridge, pop or vegetable soup cans. However, you can display them on most other refrigerators, washers, dryers, dishwashers, steel file cabinets, cast iron bathtubs, toasters, roller skates, lockers, and other steel or iron objects.
