A Möbius strip is a one-sided surface created by taking a rectangular strip of paper, giving it a half-twist, and then joining the ends together. This unique shape has fascinating properties, such as having only one boundary and being non-orientable, which means that if you travel along the surface, you can return to your starting point while being on the 'opposite' side. These features make the Möbius strip a classic example in the study of immersions and their properties.
