Ever wanted to catch a snowflake and keep it forever? You can. This is a photograph of a snowflake that fell in January 1979, but it isn’t a 27-year-old photo. It is a recent shot of a snowflake that’s been sitting in chemist Tryggvi Emilsson’s desk for 27 years, locked in a drop of that miracle of modern chemistry we call superglue.
Here’s how to do it:
- 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.
- Place a drop of superglue on the snowflake. Note: Gel glue doesn’t work. Find a brand that’s thin and runny.
- Drop a coverslip over the glue. Don’t press down hard or the flake could tear or melt from the heat of your finger.
- 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.
