In my physics book, I have students observe water falling out of a stationary cup that has a hole poked in it. Then, they watch the cup being dropped. Once it is dropped, no water comes out of the bottom of the cup, because the velocity of the water relative to the cup is zero. Malachi took the experiment to a whole new level!
