Snowflake watching is a real hobby. You need a magnifying glass and warm clothes. Bring your camera too and try to photograph the snowflakes. I think the challenge would be to be out on a day that is cold enough so your own breath isn’t melting them as you try to focus in close enough to see their patterns.
