A quick intro to the Physics of Wetting

Water forms droplets on the surface of a leaf but it spreads and completely wets the skin of a snail. Why does water behave so differently on the two surfaces? In this video we introduce the fundamental concepts of surface tension, contact angle and the difference between hydrophobic and hydrophilic materials. Also, we illustrate with examples how the physics of wetting help understand biological features in cells!
