Condition :   Excellent   
Principle :   Buoyancy, Volume, & Density 
Area of Study :  Heat & Fluids  
Equipment :   Water filled tank, paradox apparatus.
Procedure :   Hang the paradox apparatus on a horizontal bar with a hook on it.  Place the apparatus in balance by adjusting the distance of each ball from the center.  Since one ball is 1/2 the density of the other the distance from the center of the arm should be a 1:2 ratio.  Each ball has the same volume however when dipped into the water the equilibrium is disrupted.
