This long legged small insect called the Kangaroo and water insects that walk on the surface of the water. The Kangaroo River walk on the surface of the water is due to the water pressure on the skin are caused by gravity between molecules known as force between molecules (intermolecular forces) These workers make the molecules inside are molecules that surround tempting in all directions. There is no one way to do strength, especially the facial area, but the molecules of the liquid will be attracted from the molecule to the side and below only. There is no gravity to top surface of a liquid, but internal tension is called surface tension. This tension will attempt to pull the molecules at the surface of the liquid with the greatest strength. Makes the surface of the liquid to the contraction to reduce the surface area of low pressure, which pulls the molecules at the surface of the liquid inside, causing the surface tension. Water or liquid can sustain some objects on the surface. Jing Jo water walk on the surface of the water.But not because of the surface tension of water only. Water Kangaroo also have an effect, there is a long leg and thigh at the end of the oil glands are tiny hairs, as well as at the end of the Middle pair of legs help prop up trunk.
