Grayhawk,

I was drinking from the same keg of beer you were--but don't we have to
assume that we are unlucky and the heavy piston is in the batch that we
didn't weigh. For instance, in the first batch of 13, we have to weigh
both since we can not tell if the heavy piston is the one left out or if
it is in the second batch of 13, so it takes two weighings to cut the
number down to thirteen...then the process is repeated with six pistons
in each batch with one left over. But then again, maybe I've had too
many of those beers and I'm wearing the 5-gallon bucket as a hat.

I know Brent is going to dazzle us with a clever and ingenious solution,
but I'm not intimidates...he's still trying to figure out why the
chicken crossed the road.
