Have you tried the RAINBOW MILK EXPERIMENT yet? It's such a beautiful and fun science experiment! One of our all-time faves. https://artfulparent.com/awesome-rainbow-milk-science-experiment/ Simply add drops of food coloring to a shallow dish of milk, then touch a cotton swab dipped in dish soap to the color. The color explodes and dances all around as the detergent interacts with the fat molecules in the milk! Did I say awesome and beautiful?! If you haven't done this yet, it's a must try! xo,
