I got this from Neil deGrasse Tyson's twitter. Can anyone explain why this works? How does the falling cup make the water stand still? If both fall at the same speed, shouldn't there always be some water ahead of the cup?

>>	Anonymous Sun Feb 9 10:54:14 2014 No.6344444 >>6344417 The reason water spews out the side is because the water on top is pushing on it. While all the water is in free fall the pushing stops because the water on top isn't being dragged into the water underneath, they're falling at the same speed.
