Water is one of the most important substances on the planet yet mystery still surrounds many of its properties, exactly how much do we really know about it ?
What makes water so fundamentally important to life ? Why do ice cubes float ? Why does it freeze from the top rather than from the bottom ? This article delves in to these mysteries and more.
We are confronted by many mysteries, from the nature of dark matter and the origin of the universe to the quest for a theory of everything. These are all puzzles on the grand scale, but you can observe another enduring mystery of the physical world - equally perplexing, if not quite so grand - from the comfort of your kitchen. Simply fill a tall glass with chilled water, throw in an ice cube and leave it to stand.
