A mobius strip

A mobius strip is one of the strangest strips of paper in existence, yet it is remarkably easy to create. Just get a strip of paper, loop it in a circle and make one twist on it. This loop only has one side. If you run your finger on the strip, you feel both sides. A piece of paper with only one side. Remarkable! If you carefully cut the mobius strip into 2 down the middle, it turns into a big loop, not 2 loops. This big loop has 4 twists in it. If you cut it another time, it turns into a loop looping around another loop. Mobius strips are definitely a thing of complexity and amazing traits. It is truly an object to explore and ponder about. Strangely, if you twist it an even amount of times, the loop has 2 sides, if odd, 1 side.
