Abstract
A soft playing disc is made of a pliable material having a generally disc-cupped shape to provide an aerodynamically stable disc. The material from which the disc is constructed is sufficiently rigid to enable the device to maintain and hold an aerodynamically stable structure and yet is sufficiently soft and resilient to prevent or avoid damage or injury should it strike an individual.
