    > Wrap a string around the Earth, and pull it snug. Now, add an inch to the length of the string. How far off the surface will it stand?(assume it's symmetric)

    More intersting question, what if it not symmetric? That is, after adding 1" you pinch a string at a point and pull it out until the rest of string snugs the earth tight. How much of a gap will it be? Will the cat get under it? Human? Elephant? Empire State building?
