A tiny world in a fallen drop

Summary Author: Thalia Traianou; Jim Foster

This photo shows a pearl-like drop of water just breaking its bond with an ice stalactite (icicle). It was taken in the city of Florina, Greece in late December. Since the liquid drop behaves as would a simple lens, the refracted image of the tree branches and fence is inverted when viewed through the drop. The drop’s spherical shape results because surface tension minimizes its surface area. Thanks to Paul Gaintatzis for help with the image processing.
