Drink milk and create your own mustache!

Activity Idea: Color it White

Description: Kids learn mini-science facts about milk and create milk mustache photos
Grade: 3-5
  • whole milk
  • melted ice cream
  • a clear glass
  • ice chest
  • small paper cups
  • camera
  • prism


  1. Pass around the prism to let kids see the different colors in light. While kids are looking at the prism, pour whole milk into a clear glass. Ask kids why they think the milk in the glass is white? (Answer: Because it reflects all colors of light.)
  2. Explain further that the chalky mustaches that color lips after drinking a cold glass of creamy milk are caused by fat and the primary milk protein called casein. Rich in calcium, casein helps contribute to milk's white color. Even though we can't see it, light is made up of a rainbow of colors. The one time you can see the different colors is when there is a rainbow in the sky. An object is the color of light that is reflected. For example, red colored objects absorb all light colors but red. The red is reflected, so it is what we see. Milk looks white because fat and casein don't absorb any light colors. It reflects them all.
  3. Tell kids that they are going to take milk mustache photos of each other.
  4. Mix equal parts of whole milk and melted ice cream thoroughly (keep ingredients cold during use).
  5. Pour portions into the paper cups and give one cup to each student to drink and create a milk mustache.
  6. Ask kids to pose for a picture doing some kind of physical activity (pretending to make a basket, play volleyball and so forth).
  7. Display photos in the cafeteria, on a school bulletin board or at parent-community events.
