Swirling Colors Milk Experiment | Who would have thought you could do such a colorful science experiment with milk? We had fun at our Super Science Party adding a "secret substance" that would turn a tray full of milk and food coloring into a swirling symphony of colors!
DIY Naked Egg- use to show chemical reaction (dissolves calcium carbonate shell), semi-permeable membrane, osmosis, (equalization of water concentration). Very cool when osmosis is shown using food coloring to prove to students that the water is actually passing through the semi-permeable membrane of the naked egg.
Science experiment with magnets: Put iron-fortified cereal (like Total) in a bag with water. Let it sit for 20 min., then rub a strong magnet all around. Pull it up to the top and you'll see you've collected the actual iron from your cereal!
