• Water
  • Sunlight
  • A clear glass
  • A small mirror


  1. Fill you clear glass with water. The glass doesn’t need to be filled to the brim, but the higher the water is, the bigger rainbow you should get.
  2. Place your mirror inside the glass of water at an angle
  3. Place the glass so the sunlight shines into the mirror. You may have to place the mirror a little bit to find the right angle.
  4. Turn off as many lights as you can to get the best rainbow.
  5. Look for a reflection of the rainbow on the wall. You may have to adjust the angle of the mirror a little bit.
