Here is a variation of the Rainbow experiment I posted last month. Check out this blog for other science activities.
This is an experiment that kids love!!!!! you need a small flat dish, food coloring, 1/2 cup of room temperature whole milk (the fat content is important),a small amount of liquid dishwashing soap and a toothpick or cotton swab.
Pour the milk into the dish. Put a drop (or two) of a different color in each corner of the dish. Using the toothpick or swab, place a drop of the liquid soap in the center of the milk ( you can even insert the end of the toothpick into the milk). WATCH THE COLORS ROLL!
