This time of year, most of Idaho is grappling with snowfall in one way or another: cursing its existence, while scraping clumps off windshields, or sashaying down ski hills on pillowy mounds of powder.
But few know precisely how snow is made, starting with tiny snowflakes. The folks over at the American Chemical Society, a 136-year-old community of chemists, put together a short video explaining how snow coalesces in the clouds.
According to the ACS, it all begins with tiny specks of dirt, and since water molecules bond to form hexagons, the growing ice crystals form six-sided flakes as they plummet toward Earth.
