ABSTRACT:
This disclosure pertains to a circular lightweight hoop having a hollow circular cross-section, to which is removably attached a flexible wire-like element. One end of the wire-like element is removably fitted to a shaft and thence through a clutch to an output shaft of a motor contained within a portable hand-held housing also containing an operating switch and a battery. The hoop contains a pair of ports fluidly communicating atmospheric air to an otherwise sealed compartment contained within the hoop. A flap panel adjacent one of the ports, directs air into the compartment and out of the remaining port, creating a whistling sound upon the hoop being rotated by the operation of the motor.
