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.

Washed down with rusty water in a tin.
But standing outdoors hungry, in the cold,
Except in towns at night, is not a sin.”

the mother, the child,
and we three will color the stars black
in memory of his mother
who kept him chained to the food tree
or turned him on and off like a water faucet....”

In summertime with a witching wand,
In every wheelruts now a brook,
In every print of a hoof a pond.”
