Here’s a challenge for those of you living in cold country!  Try preserving a real snowflake!  Apparently, according to a blog post by David Pescovitz, “Icelandic chemist Tryggvi Emilsson came up with a way to “preserve” the structure of snowflakes using superglue and microscope slides. The snowflake seen here has been stored in Emilsson’s desk since 1979.”   We’d love to hear from you if you can recreate this amazing feat! 

The key seems to be maintaining the chill factor throughout the entire process.  Start by setting the microscope slides and superglue outside when it’s 20 degrees or colder.  Then catch a snowflake in a drop of super glue and place it on the microscope slide.  Note:  Be sure to use the lower viscosity, runny, super glue rather than the gel variety.  Then gently put another chilled microscope slide on top.  Don’t press too hard or allow the warmth of your finger to melt the snowflake.  Finally, leave the snowflake slide in your freezer for another one to two weeks.  Do not touch it with warm hands in the meantime.  (You can find the precise instructions on the other links in this blog post.)

Let us know if you manage to preserve a snowflake.  We’d love to hear from you!
