The natural tendency of the surface of water (and other liquids) to behave like an elastic sheet. It is caused by forces acting between the water molecules: the molecules at the surface are much more strongly attracted to each other, and to the molecules below them, than they are to the molecules of air above them.

• That property, due to molecular forces, which exists in the surface film of all liquids and tends to bring the contained volume into a form having the least superficial area. The thickness of this film, amounting to less than a thousandth of a millimeter, is considered to equal the radius of the sphere of molecular action, that is, the gr......

Surface tension effects allow adapted insects to 'skate' on the surface of a pond, or a needle to be 'floated' in a cup of water. The force existing in any boundary surface of a liquid such that the surface tends to assume a minimum possible area. It is defined as the force perpendicular to a li...

Surface property of a liquid causing it to act as an elastic enveloping membrane. This causes droplets to form spheres in flight. When the drop impacts it spreads, when that kinetic energy is expended the surface tension draws the droplet margins back. Materials which reduce surface tension thus increase spreading and because they decrease the cohesion between surface molecules compared with pure water smaller droplets are produced at the nozzle....

http://www.physicalgeography.net/physgeoglos/s.html

Surface tension is a property characteristic of liquids, by which the surface behaves as if it were covered with an elastic stretched skin. The effect is due to the fact that at the surface the attraction between the molecules of the liquid is unbalanced, surface molecules being attracted towards the body of the liquid, whereas in the body of the l...

Property that causes the surface of a liquid to behave as if it were covered with a weak elastic skin; this is why a needle can float on water. It is caused by the exposed surface's tendency to contract to the smallest possible area because of cohesive forces between molecules at the surface. Allied phenomena include the formation of drople...
