Synopsis:A documentary looking at the properties of water, and its importance to planet Earth
Shotlist:Water is a unique feature of earth. A substance that dominates the surface of our planet, succours life, is the material of life itself. Animal, vegetable or human; all consist largely of water.
It is water's nature to move. Through plants, round the body, round the world. As currents, spiralling the oceans, rising as they warm, sinking as they cool. As cloud, floating landwards, falling as rain. Running as rivers, sliding as snow and ice. Always in motion unless checked. Always evaporating unless sealed.
This programme looks at the properties of this familiar substance as a liquid, a solid or a gas; a substance we rely on with every breath we take.
