Tosy's AFO: Aliens Flying Object is an innovative mash-up of a classic flying ring and a boomerang that, even though it's very simple, delivers tons of can't-put-it-down fun. To launch the AFO, snap the simple plastic disc onto the hand launcher. Pull back on the string and let go. The AFO can travel up to 100 feet in the air thanks to its flexible thin blades. LED lights automatically turn on when the AFO is flying, creating a colorful light show perfect for nighttime play. When the AFO hits the apex of its arc in the air, the AFO turns around and returns to wherever it was launched.
