Timelapse footage of ice crystals forming on moist glass in air temperatures of -15 degrees Celsius (-5 Fahrenheit). The shapes of the ice crystals are influenced by the small-scale structure of the surface of the glass, with tiny scratches and other imperfections forming nucleation points for the initiation of freezing. Filmed outside in St Paul, Minnesota, USA, in winter.
