This strange band was first made in the 1800s by a German man named August Mobius. Mr Mobius studied math. He wanted to find a way to show how this band worked with math. Understand it or not, this band has only one surface. You can find this out for yourself.
If you draw a line on the surface of the paper before you twist and glue it, the line is only on one side of the paper. The paper has two surfaces. However, if you draw a line after you make the Mobius band, you can follow the line around aoo sides of the paper. In other words, the Mobius band must have only one surface.
It is also very interesting to see what happens when you cut the band. If you cut the Mobius band in half once down the line you drew, you do not get two Mobius bands. Instead, agter 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 Mobius bands.
