This flying ring launcher dramatically illustrates the effect of gyroscopic forces on motion. If the Mini X-Zylo flying ring is launched with the rubber bands pulled back straight, it wiggles through the air chaotically. But by twisting the rubber bands and giving the Mini X-Zylo a spin, gyroscopic forces send the ring flying in a straight line! Launcher includes two Mini-X-Zylo flying rings. Additional Mini X-Zylo flying rings available separately.
