Cliff Stoll in case people were wondering: https://en.wikipedia.org/wiki/Clifford_Stoll I have his original book my shelf, it was fascinating when it came out. His Klein Bottle company is here: http://www.kleinbottle.com/

The Copy on Kleinbottle.com is marvelous, its like pouring hot cocoa spiced with love: From http://www.kleinbottle.com/drinking_mug_klein_bottle.htm : "The 7 mm air space separates the inside from the outside, so ice water won't cause condensation. This extends the life of hot or cold drinks, saves energy, and helps stave off the dreaded local thermodynamic equilibrium." But seriously just read the whole page, this i…

  But seriously just read the whole page, this is like a
  bear hug from a friend I didn't knew I had.

I got one of those Klein bottles from him, and it's really beautifully done. If you are careful, you can even store some liquid or other stuff in it. I wonder if the mathematical original could do that, too.

You're not really storing the liquid in it; you're storing the liquid on it.

Earlier quoted context omitted.

But with an ordinary bottle, the edge is the point (if I may), because if a bottle had no edge, couldn't it be said that has just one ordinary surface? So in fact, what I understand so far is: - a (hollow) sphere has two surfaces, one inside and one outside, and you can't connect one to the other (you can't walk from one to the other) - a potato, or a bowl also have the same properties: two distinct surfaces - a bott…

Yeah but last time I heard, a Klein bottle being only a one sided surface can only be rendered in 4D space with the 'passing through' funnel not breaking or intersecting the curved surface and this can't be rendered in 3D space. Unless recently they've decided to relax that restriction. Nice model though and worth getting but I wonder how best to mount it in a display case.
