Does anyone know - What is fire?

[Radish]

Or is this some godly philosophical question that no one knows the answer to?
I have always wondered what exactly is fire. I mean, what state is it? It's not a solid, a liquid or a gas. It burns in air.
But just...what is it?

Any ideas, oh wonderful intellectual people of the yahoo answers community...?
