Ancient History
Artifacts and paintings depicting yo-yo-like objects date back to 500 B.C. in Greece. Yo-yos were also shown in paintings in ancient Egypt and China. In the 16th century, yo-yo-type objects were used in the Philippines. They were transported from these faraway spots to Europe and America throughout the 18th and 19th centuries.
Modern History
In 1928, Filipino-American Pedro Flores first started a company called the Yo-yo Manufacturing Company, and he began selling yo-yos in the United States. A businessman named Donald Duncan bought the idea and company from Flores in 1929. He trademarked the name "yo-yo" in 1932. With advertising, the "yo-yo" became one of the biggest-selling toys in America in the 20th century and the word "yo-yo" is now a part of common culture and no longer trademarked.
Word Origin
The word "yo-yo" means "come come" or "come back," and is from the Tagalog language in the Philippines.
Function
The yo-yo of today's world is a toy. However, while some ancient forms of yo-yos were used as toys, they were also used as offerings to the gods in some cultures. They have also been used as weapons in the Philippines.
Types
The ancient form of yo-yo was carved from a single piece of wood or crafted from terra-cotta. The inner axle that the string was tied to was stationary. Newer versions have a rotating axle that allows users to do tricks with their yo-yos, such as "walking the dog" or "sleeping."
Fun Fact
Yo-yos have traveled to space in the space shuttles "Discovery" and "Atlantis." The physics of how a yo-yo works were discovered to be quite different in zero gravity.
