Let It Snow
If you saw something like this falling from the sky, you might think that the weather outside was indeed frightful. But this dumbbell shaped object is, in fact, a super-magnified snowflake--yes, a snowflake. Not so frightful after all. This particular snowflake is a capped column, one of many types of snowflakes. The fuzzy texture on its two hexagonal ends is called rime.
