Launches flying rings 100'! A must have for this holiday season, especially if you like the Z-Curve Bow. The Zyclone allows you to launch the included 6" dia. foam rubber ring across the living room or soccer field. You decide how far to launch it by pulling it back half way or full bore! Lots of science behind this flying gadget. Many people buy 2, so they can play catch with their friends. You can launch the ring back and forth for hours with your friends. Try to catch the ring on your arm or foot! Too much fun!
