Module Abstract

The appropriate balance between cohesive and adhesive forces results in an almost spherical drop of water standing on a surface, such as a lotus leaf. This effect is called superhydrophobicity.  Many factors such as liquid type, surface and temperature will determine whether a surface/liquid combination results in a superhydrophobic effect.  Students are encouraged to evaluate all the forces acting on the surface/liquid system and write inequalities that support the observations.
