Abstract
What is the maximum overhang that can be obtained when a set of blocks of variable width are stacked so that there is one block at each level? First, we stack these blocks in a prescribed order, and describe infinite sets of blocks that yield towers with arbitrarily large overhang. We then stack the blocks in any order, and describe how they should be stacked to maximize their overhang.
