I see A LOT of cool postings on Facebook, but I usually just skim by, onto the next, without taking a second look. I took a second look at this one and I'm so glad I did! It's simple, not terribly messy, and entertaining for the kids! What could be better? This is all you need to do: Pour whole milk (it has to be whole...something to do with the amount of fat in it and the way it responds to the rest of the ingredients) into a shallow plate (preferable one with a decent lip on it...don't want it spilling out!). Add a few (or a dozen, up to you!) drops of food coloring. Then dip the tip of a Q-tip into some dish soap and poke the tip right into the colorful milk. Watch the colors swirl around like magic, and watch your kids light up as though it really is!!
