November 2006: Afghan Bands (solution)

To create the belts for the Siamese twins, take a standard Möbius band (with one half twist), then, as before, cut down the length of the strip. But instead of cutting along the centerline, cut the strip in thirds (as you will see, this will only require one cut). The procedure is demonstrated in Experiment #3 in the following video.

Solution to the bonus puzzle: To get the strip tied around the ring, put the strip through the ring and give the strip three half twists before taping. Then cut down the centerline.
