Alivia wants to know why snow is white.

Well, snow actually isn’t always white.   It can be gray from pollution or yellow from… well, ummm… let’s just say mom and dad have a good reason for telling you… ‘don’t eat snow!’

Anyway, most snow is in fact white.

Snow is made from ice crystals.  Many ice crystals together make up a beautiful snow flake.  Light passes through each ice crystal, and the light is bent and changes direction.  But we never see colors.  That’s because the light keeps moving through one ice crystal to the next and getting bent again.

It all sort of gets jumbled up.  All of the colors of the spectrum combine to make the color white.  So when you look at snow… you see white!
