I didn't ask what the composition of engine oil was. I asked you what the mystery substance exiting the pcv is. So far we have concluded that it is made up of oil and air. You yourself said that it is impossible to remove all of the water from the air in florida or anywhere else aside from the north and south poles. So as that oily air mess exits the engine, (where it was once the magical 212 degrees farenheit that obliterates everyhing) it CONDENSES back into it's liquid phase. This means not only are oil, contaminants and trace amounts of whatever else the engine blew out there but WATER too. How long that water remains in the can are a result of other factors at work: Wind, heat, increase in surface area, dryness, volatility of the liquid, and vapor pressure. This means it isn't far fetched to open a catch can and observe a mixture of the above. Anyone can share information! Sharing the right information is what matters.
