Take any long piece of paper and glue the ends of the paper together. You have made a ring. Take a second long piece of paper, twist(扭转) one of the ends through 180°, and glue the ends together.

Now you have made a Mobius band. The band is named after the German mathematician August Ferdinand Mobius who discovered it in September 1858. It is special because it is single-sided. To prove it, you can draw a line along the middle of a common ring. The line is only on one side of the paper. However, if you draw a line after you make the Mobius band, pay attention not to take the pen off the paper when drawing the line, just keep on going until you return to the starting point. Once you’ve finished, you’ll get an unbroken line which goes along both sides of the paper.

It is also kind of fun to see what happens when you cut the band. If you cut it in half along the middle of the Mobius band, you do not get two Mobius bands. Instead, after you cut the band, it turns into one large twisted ring. Then, if you cut this ring in half along the middle of the band again, you get two connected twisted rings. As an experiment, try cutting around a Mobius band one-third of the way from the edge. What do you get? Make a collection of Mobius bands — fat ones. Mark them in fourths, fifths, sixths, and cut around them. Keep a record of your results.
