Long legged insects This is called Gerridae and insects walk on water. Gerridae to walk on water, because the water surface. The force of attraction between molecules called. Forces between molecules (intermolecular forces) strength of these molecules within the molecules around it. Engage in all directions No traction to any one particular way. But the molecules on the surface of the liquid molecules are attracted to the side and below. No attraction to top The surface tension of the liquid inside, but it is known that the surface tension force is trying to force the molecules at the surface of the liquid as possible. The surface of the liquid was dropped. To reduce the surface tension, low molecular surface of the liquid inside is caused by surface tension. Liquid, so it can support some kind of object on the surface. Jing Zhou water, walk on water,
but not because of the surface tension of water alone. Gerridae also is unique with long legs and a leg glands. The tiny hairs Many of the middle pair of legs to support the body.
