A bug walking on the surface of a puddle is depending on HIGH SURFACE TENSION BECAUSE OF THE ATTRACTION BETWEEN WATER MOLECULES.
Water has a lot of interesting properties due to the hydrogen bonds that hold its molecules together. One of the interesting property of water is surface tension.
Surface tension refers to the property of the water surface, which enables it to resist an external force. The cohesive forces among the water molecules is responsible for the surface tension. The surface tension of water allow small animals such as insects to walk on water.
