This is just a little experiment we did at school. While I was doing a search on the internet I saw this on You Tube and loved it. All it takes is a little milk in a shallow bowl or plate that has an inset. Add several drops of food coloring to the milk right in the center, and then place a q-tip with dish soap on the tip in the center of the food coloring. The result is that the colors push out in a star like design.
Unfortunalty my video camera gave out so this is a brief snip of our experiment. It is a shame because some to the reactions were priceless.
