the english term bottle just appeared to be a bad translation of the german means of "fl�che".

So "fl�che" means plane, not flasche (bottle), not even "surface", which means "oberfl�che", and the corresponding term seems to have made its way into popculture.

Dissecting a Klein bottle into halves along its plane of symmetry results in two mirror image M�bius strips, which is mind blowing for non mathemathicans(can be..)

Now this is real besserwisserism, and i�m praising berlin for its pavement full of dogshit...

Oh, i�m drunk
