When I was little, I remember my dad showing me snowflake Bentley's photographs of snow crystals. Then we went outside with a magnifying glass and caught snowflakes on the sleeves of our jackets and looked at them. I think at one point we even got out a teaching microscope and took a look at some too.

This calendar is full of photomicrographs of snowflakes, so even if global warming decreases your chances of getting to look at snowflakes this winter, you can see some six-fold crystals.
