knowledge: The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering.
response: The sky appears blue due to an effect called the Rayleigh scattering.

Cool!  I saw someone with blue hair the other day.  Not sure what would possess someone to dye their hair blue!
knowledge: An optical effect called Tyndall scattering explains blue eyes.
response: I don't know but the blue in your eyes is also due to an optical effect. It is called Tyndall scattering.
