slant. Its lift depends on its speed relative to the air. Therefore, throwing into the wind makes it fly higher. Throwing with the wind makes it fly lower. Advantages The Aerobie's ring shape allows it to be caught in a variety of different ways. For example, it can be caught by thrusting a forearm, the head (when the ring is thrown high), or even a foot through the middle. Games such as "Aerosticks" and Aerogoal are designed specifically for the Aerobie. Disadvantages, special care An Aerobie ring does not float in water. It can be easier to lose than a flying disc, especially over long distances: its low profile can make it hard to spot on the ground, and, in particular, it gets caught on tree branches more easily. The Aerobie is best thrown in a wide open area such as a football or soccer field, away from bodies of water, roofs, trees, roads, etc. Adequate light is important. World records The Aerobie Pro was used to set the Guinness World Record twice for the "longest throw of an object without any velocity-aiding feature". The Aerobie's first Guinness World Record was set by Scott Zimmerman at in 1986 at Fort Funston, San Francisco. The 1986 record was broken by Erin Hemmings with a throw of on July 14, 2003 at Fort Funston. Hemmings' Aerobie was airborne for 30 seconds (not an official measurement) and was the first thrown object to break the quarter-mile barrier (402 meters or 1,320 feet). Previous to the 1986 record, the Aerobie held the world record at . It does not appear that this was recorded by Guinness. On June 7, 1988, the Aerobie became the first object to be thrown across Niagara Falls with a throw by Scott Zimmerman. In April 1987, Zimmerman threw a silver dollar taped to an Aerobie across the Potomac River. Since the introduction of the Aerobie, Superflight has offered reward money for various landmark throws. While details of the earlier rewards are unclear, the current reward is $1,000 to anyone who sets the Guinness World Distance Record.
