Winter at Minnesota is not all about blizzard, polar vortex or heavy traffic in the middle of snowstorm. It is also about beauties created by the sub-zero temperature.
Ice flowers on the window at a cold morning are among those creations by brutal cold weather.
Actually those ice flowers are also called window frost, which are formed when a glass pain is expose to very cold air on the outside and warmer, moderately moist air on the inside. The water vapor condenses on the glass to produce such a beautiful frost patterns.
Still it puzzles me why nature chooses to use bunch of tiny stripes as needle to build ice flowers, instead of other shapes?
