Möbius strip

A Möbius strip is a fascinating shape created by taking a strip of paper, giving it a half-twist, and then joining the ends together. This creates a surface with only one side and one edge, meaning if you start drawing a line along its surface, you'll eventually return to the starting point having covered "both sides" without crossing an edge. It exemplifies an intriguing concept in topology, showing how surfaces can be connected in non-intuitive ways. The Möbius strip has applications in science, art, and engineering, illustrating properties of continuous surfaces with just a single boundary.
