Eating Nails for Breakfast

Use a magnet to prove that there really is iron in your breakfast cereal.

Did you know that you can use a magnet to prove there really is iron in your breakfast cereal? The next time you’re eating a big bowl of breakfast cereal, take a closer look at the ingredients. You’ll find that your cereal contains more than just wheat and corn. Look closely and you might find iron… you know, the metal… the stuff used to make nails. Here’s an experiment to see if there really is metallic iron in your breakfast cereal. All you need is a magnet strong enough to separate the meal from the metal.
