Subject: 12 billiard ball problem



Does anybody know of an elegant solution to the twelve billiard ball
problem?

(Twelve apparently identical billiard balls, one of which is slightly
heavier than the rest, determine which is the heavier one making only three
weighings.)

I would be very grateful for a reply.
