Because making the invisible visible is beautiful. And because fire.<\/p>\n

In almost any fire, only the topmost layer of the flammable material — the area in direct contact with oxygen — is actually on fire. Even there, it often isn't the body of the fuel which is burning; instead, the heat of the fire is causing a small amount of the fuel to evaporate, and it's the fuel vapor that burns.<\/p>\n

(That's how both wood and gasoline fires work; in their solid and liquid states, respectively, the forces holding them in place are strong enough that they suppress the burning reaction. This is why it takes a while for wood to catch fire: you're using the fire to heat the wood enough to make it give off pre-soot, and that's what actually catches fire. If there's water, it will absorb a tremendous amount of the heat energy without itself heating up (see\u00a0https:\/\/plus.google.com\/+YonatanZunger\/posts\/hhDyY4DjuLv<\/a>) and thus prevent the fire from spreading. This is why water is used to put out fires.)<\/p>\n

There are a few exceptions, but they're unusual: things like monopropellant rocket fuels which contain both the fuel and the oxidizer inside them, thoroughly mixed, so that the entire thing can burn if ignited. But even in a normal rocket engine, it's only a small bit of the fuel that's burning at a time — or if not, you are having a big problem and you will not go to space today.<\/p>\n
