Most regions of the world are familiar with the amazing phenomenon of snow. Snowflakes are beautiful, uniquely crafted ice crystals. Individual snowflakes are fragile, and they quickly melt if they land on your hand. Yet, en masse they create a force to be reckoned with. They can shut down major cities while creating beautiful landscapes of snow-laden trees whose pictures decorate calendars and become the subject of artwork. They provide pleasure on the ski slopes and joy for children as they make snowmen and ammunition for snowball fights. All because they stick together.
