I was wondering what the risk is, from Wikipedia: > The swallowing of small magnets such as neodymium magnetic spheres can result in intestinal injury requiring surgery. The magnets attract each other through the walls of the stomach and intestine, perforating the bowel. The U.S. Centers for Disease Control reported 33 cases as of 2010 requiring surgery and one death. The magnets have been swallowed by both toddlers and teens (who were using the magnets to pretend to have tongue piercings). Defenders of the toy say that the rate of injury is approximately 1 injury per 100,000 Buckyball sets and less than 1 injury per 21.5 million individual magnet pieces.
