[John Purslow]

John Purslow asked the Naked Scientists:
   
Why is water so strange?

It combines two of the most dangerous and reactive elements yet is stable - and essential for life. It's colourless, odourless and tasteless, when most substances aren't. Plus it's denser as a liquid than a solid!

Why? How? We must be told!

What do you think?

I'd say Hydrogen bonds? and the very very VERY effective way they're used in water?

Though i'm no expert on the matter
