# Ship in/out of a bottle

 (+6) [vote for, against]

A Klein bottle made of transparent glass, on a stand.

Balanced somewhere on the bottle is a model sailing ship.

Thus the ship is both inside and outside the bottle simultaneously.

Hmm, it would be interesting who thought of it first. At least there's not a drone in sight.

How can the bottle be on the stand, if the stand is inside the bottle?

That's the wonder of BorgCo advanced topology.

I've never understood the fascination with Klein bottles. I don't see how putting the spout through the bottle makes it special. Sure it's a different topology, but so is a torus-shaped pillow or a mug with a hollow handle. The beer is in the mug but it's NOT IN THE MUG!!!!!!one!!!!

 A torus is just a special case of a sphere. A mug with a hollow handle has a "rim".

The point about Möbius strips and Klein bottles is that you can traverse from any point on its surface to any other point without crossing an "edge"; they are a single, undivided surface. The Klein bottle is interesting because it maps into four dimensions.

Didn't I see an Escher drawing of something like this once?

When I was at school I recall drawing a Klein Blue Bottle during the maths class in which we were supposed to be learning about Mobius etc. I simply added various fly features ie legs wings and compound eyes to a drawing of the main body of the bottle. Thinking of this was a short lived matter of joy for me. I was detected by the teacher, a rotten sadistic bastard called Cassidy, whom we called 'the blinks' on account of a nervous defect that was manifested in an exaggerated regular closing of both eyes. Ever since then, I have always connected Klein bottles with pain, fear and loathing.

 Hmmm, we have a similar reaction when subjects like glacial moraines, hanging valleys, drumlins and erratics are mentioned.

 // the teacher, a rotten sadistic bastard called Cassidy //

 Let's get this right - NOT a geography teacher ?

 Then again, while all Geography teachers are rotten sadistic bastards, there must be rotten sadistic bastards who aren't actually Geography teachers.

 They probably own an atlas, or a road map, or a picture with hills in the background though.
