In this new video, Spangler's demonstration involves getting half a cup of a cereal and placing it in a zip-top plastic storage bag to seal it closed. Then, you fill the bag three-fourths of the way with water. After allowing the mixture to set for an hour, you take a magnet, place it below the bag, and shake the bag lightly for about 20 seconds. Then, flip the bag over so that the magnet is on top, and voila, you will begin to see all the iron that was inside the pieces of cereal attracted to the magnet. You can even move the magnet around and watch as the iron in the bag follows your movements.
