Yo-yo

A yo-yo is a toy that is made up of two round parts that are connected to each other with a piece of string. When you hold one of the round parts and throw the other one down, it will spin around the string and then come back up when you pull it.

Imagine holding a toy car by a string and swinging it around in a circle. The string keeps the car from flying away and helps it spin in circles. A yo-yo works in a similar way, but you can control it with your hand.

People do different tricks with yo-yos, like making them go up and down multiple times or letting them sleep (spin) for a longer period of time. To make it do tricks, you need to practice and learn different techniques.

Some yo-yos are very simple and cheap, while others have special features and are more expensive. But at the end of the day, it's all about having fun and learning new things with your yo-yo!
