Supplies: 
  • 1 large container (such as a disposable pie tin)
  • Milk (enough to cover the bottom of the container)
  • 4 colors of food coloring (red, green, blue, yellow) in squeezable bottles
  • Dishwashing liquid in a bottle
  • White paper
Instructions: 
  1. Pour the milk into the large container. Make sure the bottom is well covered.
  2. Add a couple of drops of red food coloring to the middle of the container.
  3. Add a couple of drops of blue food coloring next to the red.
  4. Now add a couple of drops of the green food coloring next to the others.
  5. And finally add a couple of drops of the yellow food coloring.
  6. Now you are ready for the magic…..add a drop of dishwashing liquid (either by squeezing in a drop or using a cotton swab) to the middle of the food coloring.
  7. Watch the colors react and dance around creating amazing twirl and swirl patterns.
  8. Then dip your paper gently on top of the milk and food colouring and quickly pull it out and leave to dry.
  9. Once dry you will end up with a magic milk rainbow picture.  In the meantime, you can add a little more dishwashing liquid and see the colors move around again and again.
