I teach computer classes, mostly apps, but some programming, A+, etc. If I think they will benefit from knowing the bits and bytes (and who wouldn't?) I give them this problem to kick it off.

The Balance Problem

You must buy a set of weights for a balance scale to measure any amount from 1 to 250. The weights come in any whole number denomination. They all cost the same amount, but because of their extreme precision, they are very expensive. What is the smallest set of weights to accomplish this? What are they?

Helps if people like brain teasers.
