INTRODUCTION [METHOD]

Oil and water do not mix because oil has a much lower density compared to water and hence it lies on the top of the water's surface. Use a patch of oil on top of the surface of water to make a rainbow of colours in the following science experiment:

STUFF YOU NEED [MATERIALS]

  • VEGETABLE OIL
  • NON-STICK PAN
  • TAP WATER
  • EYE DROPPER

HOW TO PROCEED [PROCEDURE]

Chemistry science project - Elements and compounds
  1. Pour a non-stick pan about 15mm full of tap water from its base.
  2. Place the pan on a table or flat surface next to a bright sun lit window in your home, but make sure that the pan is not in direct sunlight.
  3. Hold the pan so that you look into the water at an angle so that the light from the light rays of the sky is reflected in your eyes.
