You would probably enjoy making your own mobius strip.
Much cheaper and
easier to understand. You'll usually get a light going
on expression when
you trace around it and show someone that it only has
one surface.

When I was 13, I was obsessed with Mobius strips in every
fashion, I
made them from paper, plastic. soldered metal, etc. I
tried to make a
Klein Bottle without the "junction" by joining the edge(s)
of a mobius
strip with strips and fastening them together, tried to
make part of a
Projective Plane, etc. My kids do not share this
obsession.
