Surface tension is a contractive tendency of the surface ofa liquid that allows it to resist an external force. It is revealed, for example, in the floating of some objects on the surface of water, even though they are denser than water, and in the ability of some insects e.g. water striders to run on the water surface. This property is caused by cohesion of similar molecules, and is responsible for many of the behaviors of liquids.
