How to preserve a snowflake with super glue

Wherein this sounds cool and I'd love to try if it would only snow in this godforsaken state


Cost is $10 and it's a simple 4-step process. Quoted:
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. The “super” in the thin, runny adhesive, which was invented during World War II, is the small molecules in it called cyanoacrylate monomers that penetrate and interlock with the microscopic forms of anything they touch. The glue hardens when the monomers link together, or polymerize, head-to-tail into long chains called polymers. This process is triggered by any minute trace of water or water vapor and progresses very quickly, which is why superglue hardens more rapidly on moist things, such as your fingers, than on the thing you’re trying to glue.
