Superhydrophobic

Caption

Water droplets are rolling on a superhydrophobic surface. The repellency of a superhydrophobic surface immersed in water causes a depression in the water, and the surface under water has a silvery shine caused by a microscopic layer of air trapped between the water and the superhydrophobic surface.
