Mobius Strip

Step 4Now what?

Now what?
Well, your Mobius strip is done. Note how it only has one side. Yes, one, not two. (Unless you want to count the thickness of the paper, but that isn't really the point...)
To show it really only has one side, put a pencil on a spot anywhere along the strip and keep drawing in one direction. You will end up where you started. Now that couldn't be if it had two sides, right?
There is more fun to be had if you now cut along the line you just drew, because you will not end up with two strips.

For more info, check out the entry for Mobius Strip on Wikipedia.

Some of Escher's drawings are also based on this concept.
