The Phantom Wet Spot
This puzzler comes from a listener in Plano, Texas. And I'm just gonna read it as he sent it. Here it is, in its grueling entirety... Kidding! It is pretty brief. But it is a good one!
He said, "I was working a little late in my office building one summer afternoon, although I couldn't see outside from where I was working. I heard thunder and figured it might be raining. When I left the building, I noticed my car had beads of water and there were a few wet spots around so there had been a light rain. It clearly hadn't rained much because it did not cool the air and the sun was shining again. As I was unlocking the door of my car, I noticed a wet spot in the space next to me. The space was empty, as were many parking spaces since most people that are already left. The thing I noticed was that the wet spot exactly fit the outline of a car. I started driving home but my mind was working on that wet spot. It seemed backwards somehow. If a car was sitting in the parking space when the rain came and was moved after the rain stopped, one would expect a dry spot. Not a wet spot. It would be a dry spot in the middle of surrounding wetness. But I had seen a wet spot in the middle of a surrounding dryness!"
So that is the whole thing. That is all you have to go on.
What was it that happened here?
