Splash crown created by a rebounding water drop. Photographed with high-speed flash. Although easily deformed,droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer. In the absence of other forces,including gravity,drops of virtually all liquids would be perfectly spherical. The spherical shape minimizes the necessary "wall tension" of the surface layer according to Laplace's law. | |
