A display mechanism for illustrating fluid dynamics includes a water basin having a base and a mass of water with a water surface within the basin. The waterwheel is supported within the basin with a majority of the waterwheel below the surface of the water for rotation about a horizontal axis. The waterwheel includes a plurality of pump tools equally spaced about the wheel with a majority of the pump tools below the surface of the water. Further, each of the pump tools includes three upwardly extending inner pipes with two of the inner pipes of equal diameter and disposed on opposite sides of a central larger diameter inner pipe and wherein two inner pipes on opposite sides of the central pipe include a piston connected together to a pivot assembly an a lower portion of the central inner pipe so that one of the pistons is at or near the top of one of the pipes while the other is at the bottom of the other pipe. A pump tools adapted to fill with water on one side of the waterwheel and to open on the other side of the waterwheel to thereby rotate the waterwheel. The pump tools are also constructed and arranged to contact two outer pipes to raise a mass of water above the level of the surface of the water. |
