Yes - it is possible to label it the surface inner and outer - see my previous comment about paint flying off the outer surface at high RPM. Edit: I guess I have to make it extra simple. 1. Where there's surface paint, that is the effective inner surface. 2. Where there's no surface paint, well guess what, that's the outer surface. 3. There's no other, 3rd possibility. It exists or it doesn't. If you're the ant, you either feel a paint line on the surface or you don't.

> it is possible to label it the surface inner and outer Not in a way that is continuous over the entire surface. You can do it locally on a small patch, but you can't extend any such local labeling over the entire surface.

Where there's no surface paint, well guess what, that's the outer surface. Sure, go ahead, make yourself a Mobius strip and try to paint it this way, without stopping anywhere except an edge. There is no way to do it--you'll end up painting both "surfaces" that you see locally. The only way to not do that is to arbitrarily stop somewhere, not at an edge (and you'll have to choose an arbitrary stopping point this way in both directions from wherever you start painting). It will not work the way painting an ordinary two-sided surface would, where you can indeed paint the entirety of one side, not stopping anywhere that is not an edge, and never reach the other side. You simply do not seem to understand the actual properties of a Mobius strip. Which is strange to me, since you can make one yourself and test whatever claims you want to make. I have one sitting on my desk.
