Mobius Strip

The simplest geometric shape, a one-sided surface. The paradox is that it is 3-dimensional, so it may be used to explain Black Holes. It has the mathematical property of being non-orientable. A model can easily be created by taking a paper strip and giving it a half-twist, and then merging the ends of the strip together to form a single strip. The Mobius strip has several curious properties. If you try to split the strip in half by cutting it down the middle along a line parallel to its edge, instead of getting two separate strips, it becomes one long strip with two half-twists in it (not a Mobius strip). If you cut this one down the middle, you get two strips wound around each other. Learn more about Mobius Strips on wikipedia.
