How Ships Float: VIDEO/DVD, This program is an introduction to Archimedes and his principle of water displacement. An ordinary brick and a piece of wood of about the same size are put into a tank of water. The brick sinks to the bottom, but the wood floats. Why? Bob Symes explains that in order to float, the water an object displaces must weigh more than the object itself. Therefore, a ship, which is hollow, displaces more water than the ship itself weighs.
