Abstract:
A rotatable performance device, such as a yo-yo, is modifiable such that the device can act as both a relatively narrow looping yo-yo and a relatively wide string trick yo-yo. Inner lobe spacers that facilitate these modifications and a method for attaching the spacers to the rotatable performance device to change its play characteristics are also disclosed.
