The surface generated on one complete revolution is the Möbius strip.

There have been several technical applications for the Möbius strip.

Because there is an odd number of them, the mechanism could not actually turn (except as a Möbius strip).

Take two Möbius strips; each has a single loop as a boundary.

Like the Möbius strip, it only has one surface.

The cyclical nature of these early pieces suggested a Möbius strip.

They will also create Möbius strips and learn about their applications.

Last, there are surfaces which do not have a surface normal at each point with consistent results (for example, the Möbius strip).

Möbius strip - An object that has only one surface.

The Möbius strip is a surface with only one "side".
