An elastic membrane is formed on water due to the property of surface tension.

(A) The surface of water acts like a stretched elastic membrane due to the property of surface tension. When a spider or insect walks on water,the weight of the insect is balanced by the vertical component of the surface tension force acting along the contact points of its legs. This prevents the insect from sinking.
