Making a Möbius strip
A Möbius strip is a two-dimensional surface with only one side, invented by the German mathematician and astrologer August Ferdinand Möbius, who was born on November 17 way back in 1790.
Would you like to make your own? Follow these few simple steps.
Step 1: Take a rectangular strip of paper and join the two ends of the strip together so that it has a 180-degree twist.
Step 2: It is now possible to start at a point A on the surface and trace out a path that passes through the point which is apparently on the other side of the surface from A.
