The tension is the result of intermolecular forces exerting an unbalanced inward pull on the individual surface molecules; this is reflected in the considerable curvature at those edges where the liquid is in contact with the wall of a vessel. Because of this property, certain insects can stand on the surface of water. A razor blade can also be supported by the surface tension of water.
