Water
Water is a chemical substance with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at temperatures above 0 °C (273.15 K, 32 °F) at sea level, but it often co-exists on Earth with its solid state, ice, and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces.

But it rains cats and dogs in the mountains, and towards afternoon, the water descends wildly and she ravages all in its path, the madwoman. That is how death comes. Without our expecting it, and we cannot do a thing against it, brothers.”
—Jacques Roumain (1907–1945)
“All water has a perfect memory and is forever trying to get back to where it was.”
—Toni Morrison (b. 1931)
