Wow great capture. I also live in Hillsborough and work at Sports Endeavors in the creative department. Hoping to unleash some landscape paintings soon :)

The description of this pleasant photo asks, "Why are bubbles always round?" The surface tension of the bubble tries to make the surface area of the bubble as small as possible, creating inward pressure on the air inside the bubble, which is resisted by the outward pressure of the air arising from heat. These forces reach equilibrium when the shape of the bubble minimizes the surface area for a given volume. This minimum is achieved by a sphere, assuming that we are talking about a single bubble.
