The President is going to a ping-pong match in Tokyo. He is taking
8 balls with him. A terrorist has implanted one of the balls with
explosives, but they add such a small amount that no one can tell the
difference. The CIA has only enough time for TWO weighings before the
match.
I know that you must weigh more than one ball on each scale and that
you can get information from the good batch of balls. Can you help?
