"the left-handed, indianrubber, counterclockwise, Lesser Spotted BREADBOX"

Oh! I am so jealous. I've always wanted to see one. I've heard of them, but I've never seen a counterclockwise version. You are so lucky to have one!

And I'm confused. You are supposed to put bread and other doughy stuff in the box?? I always thought it was a unit of measurement! Huh. Imagine that.

(who has the get well card for ES?)

My goodness me, I turn my back for half a second and you folks start talking about Klein bottles without me!

0) It is mineral.

Is it electrical?

0) It is mineral.
1)Is it electrical? No

2) Is it bigger than a Klein bottle?

Sorry VM, but now we've found out that a breadbox isn't actually a measuring device, I thought I'd better improvise.

0) It is mineral.
1)Is it electrical? No
2) Is it bigger than a Klein bottle? No

Is it smaller than the PicoCrumbox (which is about the size of the average pack of 20 (Yuck! Blech! Yucky!) cigarettes?)

3)Is it smaller than the PicoCrumbox (which is about the size of the average pack of 20 (Yuck! Blech! Yucky!) cigarettes?) Not usually.

4) Is it a household object?

Can you buy it in a supermarket?

ok, but I don't know how big a Klein bottle is...

Does it have moving parts?

5)Can you buy it in a supermarket? No (at least I would not expect to be able to buy one in a U.K. supermarket)
6)Does it have moving parts? No

Strictly speaking a Klein bottle, being one-sided, makes no distinction between the inside and the outside. Thus any Klein bottle could be said to contain the universe, thereby implying it has infinite volume. On the other hand, a real Klein bottle requires four dimensions, and no locally-two-dimensional figure in 4-space could be said to contain anything anyway (since the boundary of a four-dimensional subspace would itself be three-dimensional), so a Klein bottle actually has zero volume.

Anyway…
7) Does it contain significant amounts of metal?

7) Does it contain significant amounts of metal? Using your description, yes, using mine , no

Is it manufactured?

(note to self, don't read any posts by MuseSusan before the morning caffeine intake.) (Augh) (Did anyone else ever read Flat Stanley ?)

Does it normally fall into the category of "tool"?
