Why do water droplets bead when dropped on a waxy surface? Why can some insects walk on water? These observations can be attributed to the high surface tension of water. Surface tension is the result of attractive forces between molecules. Water’s large contribution to life on Earth depends on its unique properties. Without it, life on Earth would be impossible.
