Water is the most every day of substances. It pours from our taps and falls from the sky. We drink it, wash with it, and couldn’t live without it. Yet, on closer examination it is also a very strange substance (it is one of only a very small number of molecules which expand when cooled). Look closer again and water reveals itself as a key to a scientific story on the biggest of canvases. Water is crucial to our survival – life depends on it – but it was also fundamental in the origins of life on Earth. The millions of gallons of water which make up our rivers, lakes and oceans, originated in outer space. This book will change the way you look at water. After reading it you will be able to hold a glass of water up to the light and see within it a strange molecule that connects you to the origins of life, the birth (and death) of the universe, and to everyone who ever lived.
