This experiment is easy to do at home:
1. Pour milk into a bowl
2. Add 4-5 drops of red, blue and yellow food coloring (as far apart as you can)
3. Squeeze about a teaspoon of dish soap directly into the middle (sunlight brand works best, the other brands don't seem to work as well as we found out today)
4. Watch what happens, add more soap if it starts to slow down
