Science is one of those subjects that, when done right, really is just as fun on a Friday night at home with the kids as it is in class. This three-part series will explore fun science projects that your young scientists will enjoy at home or school.

  • several disposable cups
  • 3 different colors of liquid food coloring
  • milk, at room temperature
  • white glue
  • liquid dish-washing detergent

Instructions:

  1. Take the milk out of the refrigerator and let it warm up a little. It’ll work better if it’s not cold.
  2. Put the milk in a cup (fill the cup about 1/3 of the way).
  3. Add drops of food coloring in a triangle or square pattern.
  4. Put a drop of dish-washing soap in the middle of the food coloring design and watch the colors move. Cool, huh? Milk has fat in it, and the soap breaks up the fat. The food coloring swirls into the places where the fat used to be.
  5. Now, instead of using milk, try it with glue. Soap also prevents glue from sticking together. If you let the glue harden, you can cut away the cup and you have a colored disk.
