Message	it seems to me the basic property is that the mist (steam) keeps the overall cylinder temps lower. Detonation (pre-ignition) occurs when the temps are too high and the fuel ignites BEFORE the spark (and before the piston is at the top of the stroke) resulting in the piston being hammered by the explosion while it's still moving upward. If you cool the temperatures off a bit with the water, it helps prevent preignition. Higher octane fuel works by increasing the temp at which the fuel will ignite. I believe it might also help the combustion process go more smoothly but I'm not sure about that.
