What Is a Whirlygig?
Although there is no clear record of when the first whirligig appeared, the devices were considered to be a child's spinning toy for many years. Store displays were full of the colorful plastic or foil devices. Attached to a thin, flexible, plastic rod, children would pull their arms back and forth and watch the whirligig spin as the air moved through it. Today whirligigs have more uses and come in a variety of designs.
