You would probably enjoy making your own mobius strip. Much cheaper and

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.


My son wasn't into this stuff either and it really bothered me until his
mother pointed out that I should wait till he was older than 18 months. I
faced reality at that point, and put away the Marx Brothers movies, kid
science books, .22 caliber rifle, and assorted fishing poles for a later
date. Now, at 212 months, he's interested in every damned thing.

Be patient.
