A Klein bottle. I ran into this term on the web, and decided to find out what it really meant. I've visited a few pages, and I can't, for the life of me, figure out what it is! It's really hurting trying to understand.

Thanks Matt for submitting the link, that was sure interesting, I had no idea what a Klein Bottle was either.

I remember reading that it can't exist in our world, and that we can only demonstrate it with 3-d models, just as we show 3d objects with 2-d pictures.

Sure it can exist. Just like a mobius strip exists. I think what you might have in mind are higher dimensional objects that we can model in two or three dimensions but can really never percieve (google tesseract).

I think things like mobius strips and klien bottles were only concieved as a dirty trick to give mathematicians a headache.
