Water (H2O)
.Water (H2O)
It is the simplest compound of the two most common reactive elements, consisting of just two hydrogen atoms attached to a single oxygen atom. Indeed, very few molecules are smaller or lighter.
Although we drink it, wash, fish and swim in it, and cook with it (although probably not all at the same time), we nearly always overlook the special relationship it has with our lives.
Droughts cause famines and floods cause death and disease.
It makes up over about half of us and, without it, we die within a few days.
Life cannot evolve or continue without liquid water, which is why there is so much excitement about finding it on Mars and other planets and moons.
It is unsurprising that water plays a central role in many of the World's religions.
To the companies who sell it in bottles and other containers it is a real Money Spinner
They spend enormous amounts on advertising to convince us to purchase WATER.?

Re: Water (H2O)
I'm tempted to add that url to the What's Made You Smile Today thread!When I was visitng a friend of mine, (I only used to drink hot water at that time) she asked how I could drink tap water. I said 'don't you then?' - she replied 'no, I see what it does to my kettle'
