Se unirmos fitas (ou faixas) de Möbius,
obteremos uma Klein Bottle.
If we dissecting a Klein bottle into halves along its plane of symmetry we
get two mirror image Möbius
strips, the one with a left-handed half-twist and the other with a
right-handed half-twist. In fact, it is also possible to
cut the Klein bottle into a single Möbius strip.
Otherwise, a Klein bottle can be represented as two Möbius bands connected by an ordinary two-sided
band whose back and front sides are colored white and blue respectively as you
can see at the image below.
