  Density Set.
A cute little set of six cubes made from different metals, used to show students how different their densities can be. For cost reasons these sets rarely contain any really dense elements, such as tungsten, which is a pitty since students thus come away with the idea that lead is the densest metal, which is far from the truth. Osmium is twice as dense, and tungsten a good 75% more dense.
