Reverse-Rotation Displays produce unexpected motion. They are especially useful for teaching high school and college students principles of the physical sciences. In addition, these Displays can be used for commercial and noncommercial purposes. Another use involves the design of special purpose flywheels that are capable of storing energy and/or converting rotational speed. The Displays move in the forward direction because of a motor. They move in the reverse direction because of forces that come from magnets embedded in a Display, and the Earth's magnetic field.
