Save a snowflake? For decades?

Popular Science had this one, gotta try it sometime, but were just coming out of our cold season. And this year it never got cold enough - seemed unusually warm this year.

How It Works

1. Set microscope slides, coverslips and superglue outside when it’s 20°F or colder to chill them. Catch flakes on the slides or pick them up with cold tweezers.
2. Place a drop of superglue on the snowflake. Note: Gel glue doesn’t work. Find a brand that’s thin and runny.
3. Drop a coverslip over the glue. Don’t press down hard or the flake could tear or melt from the heat of your finger.
4. Leave the slide in a freezer for one or two weeks and don’t touch it with warm hands. The glue must completely harden before the snowflake warms up.
