Make a Rainbow

 You will need the following:

  •  A clear glass jar with a wide mouth
  • Water

  • A mirror (small enough to fit in the glass)

  • A flashlight

  • A room with white walls

 Flashlight-glass

  1. First, fill the glass with water. Then carefully place the small mirror into the glass jar, at an angle.
  2. Next, turn the lights off so that you will be able to see the rainbow better.

  3. Last, aim the flashlight toward the mirror in the jar. Change the angle of light from the flashlight or change the angle of the mirror until you can see the rainbow on the wall or ceiling.   What colors do you see?
