The volunteer may get dizzy from spinning. '''Setup:''' 1. Set Rotating Platform out on the floor. 1. Level the platform '''Cautions, Warnings, or Safety Concerns:''' 1. Demonstration may require practice. 1. Fingers may get caught in the spooks of the moving bicycle wheel. 1. Do to the high rotational speed of the bicycle wheel, stopping the wheel can be difficult. '''Demonstration:''' First have the volunteer raise the bicycle wheel vertically over there head, with the wheel not spinning and then with it spinning. The volunteer must hold the spinning bicycle wheel by one end of its axle horizontally at arms length. Have the bicycle wheel spun up to high speed by hand and give it to either the instructor or a volunteer or whomever is standing on the rotating platform. Again have them hold the bicycle wheel firmly by its handles while standing on a rotating platform to help illustrate Newton's third law (action and reaction) and the conservation of angular momentum. One can sit on a stool that is placed on the rotating platform as well. The person now can rotate one direction or the other by turning the axis of the bicycle wheel in different directions. For best results, orientate the bicycle wheel's axis perpendicular to it original direction, so that it is vertical the rotational axis of the platform. This well transfer the most angular momentum to the rotating platform to make the platform and person rotate the opposite direction of the spinning bicycle wheel. ||attachment:RotatingPlatform-02-250.jpg||attachment:RotatingPlatform-03-250.jpg||attachment:BicycleWheel-01-250.jpg|| '''References:''' 1.
