A button or coin battery can burn through a child's throat in as little as two hours. From 2011 through 2021, swallowed or inserted coin batteries sent an estimated 54,300 people to the emergency room and killed 27. Small, high-powered magnets are a danger too, because two or more swallowed magnets pull together inside the body. Taking them out often means surgery to repair the stomach and intestines.
