Aerobie

An Aerobie is a flying ring used in a manner similar to a flying disc (Frisbee), for recreational catches between two or more individuals. The Aerobie is a ring, rather than a disc. An Aerobie is also lighter, and is more stable in flight. It can be bent to tune it for straighter flight. Since it has very low drag and good stability, it can be thrown much farther than a flying disc. The ring is only about 1/8 of an inch (3 mm) thick. The Aerobie was used to set two former world records for thrown objects.

Designed in 1984 by Stanford engineering lecturer Alan Adler, the Aerobie has a polycarbonate core with soft rubber bumpers molded onto the inner and outer rims. The outer rim has a spoiler designed to impart stability.

"Aerobie" also refers to other products made by Aerobie, Inc.
