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. A waterwheel is supported within the basin. The waterwheel includes a plurality of pump tools equally spaced about the waterwheel and adapted to fill with water on one side of the waterwheel and to open on the other side of the waterwheel. Each of the pump tools includes three upwardly extending inner pipes. The plurality of pump tools are arranged to contact two outer pipes and are adapted to fill with water on one side of the water wheel.

1. A display mechanism including a water wheel for illustrating fluid dynamics, said mechanism comprising: a water basin having a base and a mass of water with a water surface within said basin;a water wheel and means supporting said water wheel within said basin with a majority of said water wheel

1. A display mechanism including a water wheel for illustrating fluid dynamics, said mechanism comprising: a water basin having a base and a mass of water with a water surface within said basin;a water wheel and means supporting said water wheel within said basin with a majority of said water wheel below the surface of water for rotation about a horizontal axis and said water wheel including a plurality of pump tools equally spaced around said water wheel with a majority of said pump tools below the surface of said water;each of said pump tools including three upwardly extending inner pipes with two of said inner pipes of equal diameter and disposed on opposite sides of a central larger diameter central pipe and said two upwardly extending inner pipes each including a piston connected together through a pivot assembly in a lower portion of said central inner pipe so that one of said pistons is at or near the top of said pipe when the other of said pistons is near the bottom of said other inner pipe;each of said pump tools pivotally fixed to said water wheel and each of said pump tools including a top motorized control valve and a bottom motorized control valve and three motorized valves surround the piston and means including said motorized control valves for opening said top and bottom valves at the bottom of said water wheel and for closing said bottom of said motorized control valves at or near the top of said water wheel so that the pump tools are filled with water to thereby cause the water wheel to rotate due to the weight on the water filled pump tools on one side of said water wheel;a pair of upwardly extending outer pipes adjacent said water wheel and extending upwardly at a distance equal to the diameter of said water wheel and wherein the radius of one of said pair of upwardly extending outer pipes is at least two times the radius of the other of the said upwardly extending outer pipes;an upper water tank and means for sealingly positioning two of said three upwardly extending inner pipes within said pump tool with said pair of upwardly extending outer pipes adjacent to said water wheel whereby the weight of said water in said upwardly extending outer pipes will cause the piston in the upwardly extending inner pipe to be sealingly fixed thereto to move downwardly and the piston on the other of said upwardly extending inner pipes to move upwardly to force the water in said upwardly extending inner pipe into the upwardly extending outer pipe with the smaller diameter to a level above the surface of the water in said basin; andmeans for unsealing and repositioning said upwardly extending inner pipes away from said upwardly extending outer pipes and for opening said motor control valve in said pump tool so that said pump tool with open control valves moves upwardly as the water wheel rotates. 2. A display mechanism according to claim 1 in which said basin is confined by a transparent structure. 3. A display mechanism according to claim 2 in which the water wheel includes between ten and twenty pump tools that are spaced apart by about 18° and 36°. 4. A display mechanism according to claim 3 which includes sixteen pump tools equally spaced by about 22.5° around said water wheel. 5. A display mechanism according to claim 4 that includes a plurality of water wheels each of which include a plurality of pump tools. 6. A display mechanism including a water wheel for illustrating fluid dynamics, said mechanism consisting of: a water basin having a base and a mass of water with a water surface within said basin above said base;a water wheel and means supporting said water wheel within said basin with a majority of said water wheel below the surface of water for rotation about a horizontal axis and said water wheel including a plurality of pump tools equally spaced around said water wheel with a majority of said pump tools below the surface of said water;each of said pump tools including three upwardly extending inner pipes with two of said inner pipes of equal diameter and disposed on opposite sides of a central larger diameter central pipe and said two upwardly extending inner pipes each including a piston connected together through a pivot assembly in a lower portion of said central inner pipe so that one of said pistons is at or near the top of said pipe when the other of said pistons is near the bottom of said other inner pipe;each of said pump tools pivotally fixed to said water wheel and each of said pump tools including a top motorized control valve and a bottom motorized control valve and three motorized valves surrounds the piston and means including said motorized control valves for opening said top and bottom valves at the bottom of said water wheel and for closing said bottom of said motorized control valves at or near the top of said water wheel so that the pump tools are filled with water to thereby cause the water wheel to rotate due to the weight on the water filled pump tools on one side of said water wheel;a pair of upwardly extending outer pipes adjacent said water wheel and extending upwardly at a distance equal to the diameter of said water wheel and wherein the radius of one of said pair of upwardly extending outer pipes is at least two times the radius of the other of the said upwardly extending outer pipes;an upper water tank and means for sealingly positioning two of said three upwardly extending inner pipes within said pump tool with said pair of upwardly extending outer pipes adjacent to said water wheel whereby the weight of said water in said upwardly extending outer pipes will cause the piston in the upwardly extending inner pipe to be sealingly fixed thereto to move downwardly and the piston on the other of said upwardly extending inner pipes to move upwardly to force the water into upwardly extending inner pipe into the upwardly extending outer pipe with the smaller diameter to a level above the surface of the water in said basin; andmeans for unsealing and repositioning said upwardly extending inner pipes away from said upwardly extending outer pipes and for opening said motor control valve in said pump tool so that said pump tool with open control valves moves upwardly as the water wheel rotates. 7. A display mechanism according to claim 6 that includes fifteen pump tools equally spaced by about 22.5° around said water wheel. 8. A display mechanism according to claim 7 which includes a model of a generator driven by water from said pump tools. 9. A display mechanism according to claim 8 that includes a mechanism for positioning a pump tool at the bottom of the water wheel. 10. A display mechanism according to claim 9 that includes a mechanism for sealingly connecting an inner pipe to an outer pipe. 11. A display mechanism according to claim 10 that includes means for sealingly clamping said two inner pipes to said two outer pipes.
