Snow isn’t actually whiteiStock/elenaleonova
That’s right. Snow is actually clear. Snowflakes are made out of ice crystals, so when light passes through, it bends and bounces off each individual crystal. The entire spectrum of light is reflected back to our eyes, and we see white snow. So there’s actually no such thing as a White Christmas, but that sounds a lot catchier than Translucent Christmas. (Check out these stunning photos of national parks covered in snow.)
Snowflakes always have six sidesiStock/tothgaborgyula
It’s science. The water molecules that snowflakes are made of can only fit together in a way that results in a six-sided ice crystal. So those snowflake decorations and ornaments you see with five or eight sides? Don’t buy them. You’d be breaking a law of nature.
