How do you extract iron from cereal?

Get a cereal with a high iron content. Look at the nutrition label. It should be around 100%. Place crushed cereal in a zipper lock bag. Add a small amount of water. Enough to make it the same consistency as a creamy soup. Seal the bag closed. Get a strong magnet, rub it over the bag slowly. You will see the iron build up around the tip of the magnet.
