ABSTRACT:
In one embodiment a device is provided for visually demonstrating stagger. In this embodiment, the device includes first and second tires coaxially mounted on an axle, wherein the first tire has a smaller diameter than the second tire. The device also includes a member configured to be pushed or pulled by a person. The device may be pushed or pulled on a flat surface, such as a paved road. When the device is pushed or pulled in a forward direction, the first and second tires will rotate at the same rotational speed, but because the second tire has a larger diameter than the first tire, the second tire will travel a greater distance than the first tire during each tire rotation. Thus, the device will move in a curved path.
