Our food has vitamins, minerals, and nutrients that we need to survive and be healthy. Did you know that one of those things is iron? Turns out, iron is a metal and our scientist this week wanted to test if it was magnetic. The cereal Total has the highest concentration of iron of any breakfast cereal, so we used that. All you have to do is place the cereal in some water and hover a magnet over the flakes. Be gentle with your movements, but you'll see you're able to move the cereal around the water with the magnet. Now we're wondering what our body does with iron and why it's so essential.
