  This is what you get off you cut a Möbius strip along its length. And if you were to cut it again now, you’d get two intertwined rings.

    Wait, really? I thought intertwined rings was the first thing you got.

    But I haven’t thought about this for a few decades.

      Here’s a video: youtube.com/shorts/KfbCbYSebW0

      Apparently if you cut it just once, but not along the centerline, off to one side, you then get a normal ring and a twisty one intertwined. Things are weird: youtube.com/shorts/QmrIPBavH8o
