Consider a contest where the challenge is to find the greatest height  from which the contestant in the figure below is able to drink water  through a straw. Find the theoretical limit on the vertical distance h between the open top surface of the liquid and the top of the straw. Hint:  Assume (however unlikely) the contestant can create a perfect vacuum at  the top of the straw. (Assume that the contest is held at a location  where the cups are exposed to atmospheric pressure.)
