PURPOSE: To illustrate Archimedes' Law in a counterintuitive manner.
DESCRIPTION: A block of wood is "floated" in a volume of water much smaller than the volume of the wood block. The water is poured into a container the same shape, but slightly larger than the wood block, then the wood block is inserted. In the wonderland world of the physicist, a battleship could be floated in a bathtub using one cup of water, if the tub were the right shape!
