Energy-converting machine For a toy that looks so simple, yo-yos have a fair bit of science governing their operation. It is the physics that is going on that makes it keep spinning for a long time, sleep or hang at the end of the string and climb back up again. Putting it simply, yo-yos are energy-converting machines.

China history of toys … in a Greek reference to yo-yos made from wood, metal, or painted terra-cotta. It is believed, however, that the yo-yo originated in China at a much earlier date.

A yo-yo (also spelled yoyo) is a toy consisting of an axle connected to two disks, and a string looped around the axle, similar to a spool. It is an ancient toy with proof of existence since 500 BCE. The yo-yo was also called a bandalore in the 17th century.

Versions of the yo-yo are said to have originated in ancient Greece or even earlier in China, but the first yo-yo craze seized Americans in the mid-19th century when several manufacturers patented improvements to the toy. At the beginning of the 20th century, Scientific American published directions for making yo-yos.

Made of two disks connected by an axle that has a string attached to it, the yo-yo falls and rises back to the hand by unwinding and rewinding on the string. The disks are of equal size and weight and are made of plastic, wood, or metal. As a person drops the yo-yo, the string that is wound around the axle releases.

Pedro Edralin Flores Pedro Edralin Flores (26 April 1896 – 3 January 1964) was a Filipino businessman and yo-yo maker who has been credited with popularizing yo-yos in the United States. He patented an innovation to yo-yos that used a loop instead of a knot around the axle, allowing for new tricks such as the ability to "sleep."

Yo-yos weren't made out of plastic until the 1960s. Originally, they were made out of wood. This meant some yo-yos had an uneven spin because of the type of wood! In the 1990s, they began to make them out of metal.
