Yo, man, do you know where yo-yo comes from? No, I'm not asking you to tell me the name of the local toy store. Sorry, let me rephrase it. Can you tell me its history? Friend, do you think the yo-yo was invented by Donald Duncan? Forget it! Yo-yo has a history of nearly 1000 years!

At that time, children all over the world were already playing with a similar toy, but it was not called a yo-yo at that time. Legend has it that the yo-yo originated in China. As early as 500 BC, children in ancient Greece were playing with a small toy similar to a spool, and archaeologists also found the same specimen in other countries, including Egypt.

What does it look like? The early yo-yo was made of wood, metal and even clay and decorated with pigments. It consists of a small round rod connected between two disks. A thin rope is tied to the round rod, and the other end of the rope is tied to the finger. When the disc is thrown, it will roll back and forth around the rope!

Because of its simplicity and fun, yo-yo soon spread from China to Europe. In the Philippines, it began to be called yo-yo! "Liu Liu" means "come back", just like the way it is played.

On April 65, 2002, the yo-yo was sent into space by NASA's space shuttle Discovery. As part of its research plan, it will participate in space experiments.

Although the yo-yo has only repeated its movements back and forth for thousands of years, its popularity in the world will never stop.
