Apparatus for demonstrating buoyancy of fluids, consisting of a flat-ground glass tube and a plastic disc with rubber covering to form a base plate to which a long string is attached.
The base plate makes a watertight connection with the glass tube and when both are immersed in water, the plate does not sink because buoyancy keeps it pushed up against the tube.
