Ok, here's the riddle and solution, and if you find
anything wrong
There are 12 billiard balls on a pool table that all
look exactly alike. They all have the same weight, except
for one. This oddball (no pun intended) has a weight
that is either slightly greater than or slightly less
than the weight of all the other billiard balls. However,
you do not know which ball this is. Using a balancing
scale and nothing else, your job is to figure out which
one has the differing weight. The weight difference
is small enough that you can not tell just by weighing
them with your hands. The limitation is that you can only
use the balancing scale 3 times. Figure it out.
(Hint: it is much harder than you think!)
