The next trick I'm going to teach you is the follow up to the Throw Down, it is called the Sleeper. The Sleeper is a trick you use for other tricks. Basically, you start with a Throw Down, and the yo-yo stays spinning. And that is called a Sleeper. With the Sleeper, the stronger you throw, the longer it will stay spinning, or sleeping. With a good, strong throw, the yo-yo can sleep for minutes, up to ten minutes, depending on how strong you throw it. And that's the Sleeper.
