"how would you use a barometer to measure the height of a building?" (one ans: drop it and see how long before it hits, height = 1/2gt^2)

The problem with this question is that you didn't mention to the candidate that they are also in posession of a watch. Of course, they can still attempt the elegant and accurate "one-mississippi, two-mississippi, three-mississippi" solution.

Anyway, wouldn't a barometer be useful in mesuring a building's height, since there would be a relative pressure difference between top and bottom? I'm sure a formula could be worked out...

    The point of this question is to answer the question in any way possible without using the barometer for its obvious purpose.

    For instance by going to the owner of the building and offering to trade one barometer for the answer to how tall the building is...
