Today's photo is a frozen soap bubble. I shot this in my backyard with the temperatures in the low 20's. This one is shot with a macro lens, but you do not need a macro lens to shoot them. The ice cystals inside the bubble form a new design every time, so no two frozen soap bubbles are the same. I liked this one because of the variety of shapes it contains.
Today's photo is a frozen soap bubble taken against a background of snow. Like snowflakes, the frosty design that forms inside each bubble is unique. The soap bubble forms the perfect sphere while the water vapor in the air inside the bubble condenses and crystalizes to create the frosty design. According to Caltech, frost crystals have similar shapes as snow crystals. These crystals resemble "fernlike stelllar dendrites" often found on snowflakes. Frozen soap bubbles are short-lived and burst and collapse within a minute or two, but they are amazing to observe.
