Whirligig

A whirligig is an object that spins or whirls, or has at least one member that spins or whirls. Whirligigs are also known as pinwheels, buzzers, comic weathervanes, gee-haws, spinners, whirlyjig, whirlybird, or plain whirly.

Whirligigs are most commonly powered by the wind but can be hand or friction powered or even powered by a motor. They can be used as a kinetic garden ornament. They can be designed to transmit sound and vibration into the ground to repel burrowing rodents in yards, gardens, and backyards.

Whirligigs can be divided into four categories: Button, String, Friction and Wind Driven

Button whirligigsButton whirligigs (also known as button spinners and buzzers) are the oldest known whirligigs, requiring only a piece of clay or bone and a strip of hide.

Native American cultures had their own version of this toy in 500 BC.

Many a child of the Great Depression from the southern Appalachians and Ozarks remembers a button or token, or coin and a string as the primary spinning toy of their youth.

String whirligigs

String powered whirligigs require the operator to wrap the string around a shaft and then pull the string to cause the whirligig’s motion. String Whirligigs have ancient origins.

The bamboo-copter or bamboo butterfly, was invented in China in 400 BC. While the initial invention did not use string to launch a propeller, later Chinese versions did. The first known depictions of whirligigs are string powered versions in tapestries from medieval times.

Friction whirligigs

Friction whirligigs, also called Gee-Haw's, depend on the holder rubbing a stick against a notched shaft resulting in a propeller at the end of the shaft turning, largely as the result of the vibration carried along the shaft. The motion needed to power a friction whirligig is very similar to rubbing sticks together to create fire. Friction whirligigs are another staple of craft shops and souvenir stores in the Appalachian Mountains.

Wind-driven whirligigsA wind-driven whirligig transfers the energy of the wind into either a simple release of kinetic energy through rotation or a more complicated transfer of rotational energy to power a simple or complicated mechanism that produces repetitive motions and/or creates sounds. The wind simply pushes on the whirligig turning one part of it and it then uses inertia.

The simplest and most common example of a wind-driven whirligig is the pinwheel. The pinwheel demonstrates the most important aspect of a whirligig, blade surface. Pinwheels have a large cupped surface area which allows the pinwheel to reach its terminal speed fairly quickly at low wind speed
