ABSTRACT:
A flying amusement device including first and second rotary elements separated by a hub. Each of the rotary elements includes a set of lift members which provide lift in a common direction when the device is rotated about the hub. A length of flexible line is connected to the hub and wound thereabout prior to use. The device is held in the user's hand with the free end of the flexible line connected to the user's throwing hand. The device is then thrown outwardly from the body of the user with a snapping motion of the wrist to impart rotation to the device. This rotation produces lift, and further rotation is imparted to the device due to the device unwinding from the flexible line as it travels away from the user. Upon fully unwinding the flexible line from the hub, the continued rotation of the device causes the flexible line to be rewound upon the hub, thus drawing the device back towards the user. During the travel of the device away from and towards the user, the continued rotation of the device produces lift which causes the device to fly through the air.
