You are walking in the middle of a desert. Suddenly you see a pole,
approximately 1 meter long, and with a diameter of a finger. You lift it. You
sense that the denisty of the pole is not homogeneous. You realize that If you
won't find its center of mass quickly, something horrible will happen.

How can you do it?


The answer should be accurate enough to balance the pole on your finger. (pole
parallel to the ground, perpendicular to the finger)
