 See these magnets? They can make holes in your stomach. Seriously, I know. They look a little like jewelry, so you might think it's cool to fake a nose or tongue piercing. But don't try it. Trust me. Never put a magnet in your nose or mouth. Don't let your baby sister or brother play with them either. You can easily swallow these magnets by mistake. Then the magnets can connect inside your body, just like on the outside. You could die. If you think you have swallowed a magnet, tell your parents and call a doctor immediately because magnets go in easier than they come out.
