This Week’s Kentertainment:
First you weigh 6 pennies, 3 on each side of the scale. If one side
weighs more than the other, then the penny that weighs more is on that
side. If the scale is balanced, that means the penny that weighs more
is included in the group of pennies that haven't been weighed yet. Now
you know which group of 3 the heaviest penny is in. Now take two of
the pennies from that group and put them on each side of the scale. If
one weighs more than the other, it is the heaviest penny. If they both
weigh the same, the heaviest penny is the one that isn't on the scale.
