Word of the Day for Friday April 7, 2006

Hydrometer
A short stubby cylinder surmounted with a long graduated tube. The whole is sealed and weighted so that it floats upright in a liquid always displacing its own mass of liquid thus indicating by the depth to which it sinks the density or specific gravity of the liquid. Used for measuring alcohol, salt and sugar concentrations in solution.
