The Klein bottle is a fascinating mathematical surface that challenges our everyday understanding of geometry and space. It is a non-orientable surface, meaning it has no distinct “inside” or “outside,” much like the Möbius strip. However, while a Möbius strip has an edge, the Klein bottle does not—it’s a closed surface without boundaries. To construct it properly, you’d need four dimensions, because in three-dimensional space, the surface must pass through itself, which isn’t truly accurate to
