摘要：
A rotatable performance device, such as a yo-yo, is modifiable such that the device can act as a relatively responsive device for beginners and a relatively stable device for advanced users. Spacers that facilitate these modifications and a method for configuring the spacers to change the device's responsiveness and stability are also disclosed.
