This week, those who live in the northern hemisphere will cross their fingers in hopes of a dusting of snow for the holidays. Everyone loves snow for making snowballs and snow forts, plus a blanket of fluffy white stuff just makes it feel like winter. But zoom in and you’ll see one of nature’s most magnificent marvels: the snowflake. Geometric and intricate, snowflakes look like the work of a master sculptor. In fact, they are the product of atmospheric conditions and the unique crystal properties of ice. You can learn how they form in our Video of the Week by the American Chemical Society on the chemistry of snowflakes. That way, even if it doesn’t snow where you live, you can get a glimpse of their extraordinary, delicate beauty and the amazing process by which they form.
