Lotsa Knots

The circumference of the Earth is approximately 25,000 miles. If we made a circle of wire around the globe, that is only 10 miles  longer than the circumference of the globe, could a flea, a mouse, or even a man creep under it?

  It is easy to compare R and new R [original perimeter = 2xPIxR, length of wire = 2xPIx(new R)] and find out that the result is about 1.6 m. So a smaller man can go under it and a bigger man ducks.
