Re: re: Richard Feynman
"Surely your're joking Mr Feynman" is well worth reading.
As I recall (almost certainly incorrectly) it was that autobiography (could have been the other one, maybe even both, and probably elsewhere, too) where he asked which direction a rotating lawn sprinkler (the type with the S-shaped arms) would rotate if you put it underwater and pressurized the water (relative to the air pressure on the sprinkler's hose. He made a convincing argument that it would go one way. Then made a convincing argument it would go the other way.
He didn't answer that one in the book (or books). Sorta like Eric Morecambe's running gag about the two old men in deckchairs and one says "It's nice out., isn't it?"
---------Spoiler Alert------------

"It's nice out, isn't it?" "Put it away before you get arrested."
The sprinkler doesn't move in either direction. But if you're careless about the experiment, you end up flooding the basement where the tank was.
