Though hydrogen and oxygen are common in the universe, liquid water (especially clean, drinkable water) is an extraordinary phenomenon. Water is the only natural substance found on Earth in all three physical states: solid (ice), liquid (water), and gas (vapor), and within a narrow temperature range. Though water molecules are detected in interstellar clouds, comets, and even as ice on Mars, liquid water in stable, drinkable form is rare, perhaps even unique. When we sip water from a glass, we are enjoying a rare cosmic delicacy! To realize that we are cradled in an extraordinary, delicate, and rare cosmic gift.
