This is one of our favorite classic experiments that never gets old!

Today our friend Lucy gave it a whirl. Start with a plate of milk. (Whole milk works best and we warmed it for 30 seconds in the microwave since it came straight from the fridge.) Then add several drops of food coloring. Finally dip a q-tip in some dishwashing soap and add a drop of soap to the milk. Watch the colors swirl and mix! So amazing and it lasts for quite a while! When the colors do stop moving add another drop of soap and watch them start swirling again!
