Möbius strip band

A Möbius strip band is a surface created by taking a long strip of paper, giving it a half-twist, and then joining the ends together. This results in a one-sided surface with only one boundary edge, meaning if you trace along the band, you'll find yourself on both "sides" without crossing an edge. Its unique geometry demonstrates properties of non-orientable surfaces, making it a fascinating object in mathematics and topology. The Möbius strip challenges our intuition about sides and edges, illustrating how a simple twist can create a surface with unusual and intriguing properties.
