Abstract
A racket for playing ball games especially with foam balls. An ankh (without the cross) shaped inner inflatable portion is covered by an outer racket shaped envelope. The toroidal portion of the ankh stretches the outer envelope to develop a rigid racket. The outer, stretched, envelope's surfaces are used as the ball striking surfaces. A squeezable pump located in the handle is used for inflating the racket. A manually operated valve located in the handle is used to deflate the racket for convenient storage.
