Yet when they do, what is known as an oil slick appears. An oil slick creates a colourful layer of oil that floats on the surface of the water. This layer is highly reflective due to the light wave interference between oil, air, and water.
This undulating refractive index makes for shifting colours that move and change with the light. You will see the same effect in Super Oil Slick—an extremely popular Thinking Putty colour that is downright mesmerizing.
