Create a Rainbow


Make a rainbow and learn how light is made up of different colors.

What You Need

  • A handheld mirror
  • A shallow pan
  • A sunny day

What You Do

  1. Fill the pan with water and put it on a table next to a window.
  2. Put the mirror on one side of the pan so that you can see the water reflected in the mirror.
  3. Now tilt the mirror so that it catches a bit of sunlight and reflects it back onto the wall next to the window.
    Continue tilting the mirror at different angles and moving the pan around until the sunlight on the wall splits into a beautiful rainbow.
  4. Explain to your child that water splits sunlight into its seven different colors. The mirror reflects these colors on the wall in the form of a rainbow.
