A Möbius strip has only one edge and one side. It is created by taking a strip of paper, giving it a half-twist, and then joining the ends together. If you trace the edge with a pencil, you will return to your starting point after traversing the entire length of both the "top" and "bottom" sides, which are in fact a single surface. | 𝑶𝒑𝒆𝒏𝑴𝒂𝒕𝒉𝑪𝒊𝒓𝒄𝒍𝒆
