The circumference of the Earth is approximately 40,000 kilometers, and someone has just made a metal band that circles the Earth, touching the ground at all locations.
You come along at night, as a practical joke, and add just 10 meters to its length (one hundredth of one kilometer !)
It is now one fourmillionth longer, and sits magically just above the ground at all locations
How far has it risen … could a flea, a rabbit or even a man squeeze underneath it?
