The Wobblo is a strange and singular toy that seems to defy the laws of physics. It looks like a plastic doughnut, but this casing contains a weighted metal ball that generates unpredictable patterns of movement. When you rotate the Wobblo in your hand, the ball starts spinning, creating some really magical movements. Place it on a table or leave it in your hand, and watch as it lurches about, falls on its side, only to right itself the next moment, then spins off to the side. Prepare to be amazed! Makes for an excellent desk toy, and the bright colors and mesmerizing movement makes the Wobblo friendly as a therapy toy for children with autism.
