Scott Mavers Möbius strips did have a practical application back in the days of tape recording: tape with a half-twist (continuous loop tapes) could double the playing or recording time without having to stop and run the tape in the other direction (even when stop and rerun was automatic, there would still be a small temporal discontinuity). Also typewriter ribbons with a half-twist could use ink from both sides of the ribbon and not have to be replaced as often. Some contemporary higher-tech applications are mentioned here:

The Mobius strip is a fundamental structure in the study of surfaces. You'll find many surfaces can be constructed from it. It's the simplest non-orientable surface.
