Surface tension is the tendency of liquid surfaces at rest to shrink to the smallest possible surface area. Surface tension is what allows objects with a higher density than water, such as razor blades and insects (such as water striders), to float on the water’s surface without becoming submerged.
Cohesive forces between molecules cause the surface of a liquid to contract to the smallest possible surface area. This general effect is called surface tension. Molecules on the surface are pulled inward by cohesive forces, reducing the surface area.
