Abstract A Mobius band type amusement device comprising an initially flat rectangular elongated strip of flexible material having its ends joined after giving it a half twist (180*) or an odd number of half twists. A length of tubing, preferably transparent, is mounted on or integrally formed with both side surfaces of the Mobius strip, with its ends joined to form an endless tube which contains a ball or plurality of balls for travel in the tubing in a path which is continuous without going around an edge. Preferably the strip and tubing are made of flexible plastic material, not necessarily the same material, and the ball or balls are steel. Movement of the balls in the tubing may produce an audible sound which adds to the interest of the observer handling the device.
A Mobius band type amusement device comprising a. a Mobius band made of an initially flat rectangular strip of flexible material having its ends joined after giving the strip a half twist or an odd number of half twists, b. a length of flexible tubing mounted on opposite side surfaces of the Mobius band and having its ends connected together to provide an endless bore in the tubing, and c. a ball movable in the tubing in a continuous endless path without passing around an edge of the strip.
