Inspired by ideas for re-using toilet roll cores.
A Klein Bottle has, theoretically, an infinite surface area, since it has only one surface and a single edge.
Therefore, a toilet roll wound on a Klein Bottle will have a similar infinte surface area.
Therefore it can never run out .....

Oh dear oh dear. No. A Klein bottle has
an unbounded surface, not an infinite one.
In this sense it is no different to a sphere. |
|
|
Also, I suspect that toilet paper wound on
a Klein core would come off in the form a
Möebius strip. Do you really want to wipe
your bottom on something with only one
surface? |
|
|
no-one likes a smart arse! |
|
|
Who's calling me smart??? |
|
|
It's true that puppies also have one
useable surface. But they're much more
absorbent and can be cleaned. |

// A Klein bottle has an unbounded surface, not an infinite one // |
|
|
Yes, we know.... just testing. |
|
|
We find the whole Möebius strip thing deeply disturbing. |
|
|
// and the puppies do what? // |
|
|
Disappear into hyperspace, possibly ..... |
|
|
W further propose a stylish tessseract-based holder for the core. |
|

A Tellytubby..... could be a complement, could be anything .... |
|
|
I shall mull on this mootness. |
|

Now I may be wrong on this, but all of the Klein bottles I've seen only have a single concavity. This would make it impossible to use a standard pass-through mounting. You could mount it gravitationally (i.e., "set it") on a peg, but the concavity will need to be / not be filled with tissue paper as well. I think the only way out would be to have an electromagnetic support in that tesseract, and a ferrous core so that it can be magnetically suspended. However, this would naturally be almost entirely friction-free, so if you gave the endless roll a yank, and it never stops... |
|
|
I shall have to mull on that one too. |
|
|
// Why not use donuts ? // |
|
|
These too have one useable surface .... are you proposing also that they are "cleaned and used again" ? |
|
|
If so, for what function ? |
|
|
Are we talking chocolate-coated ring doughnuts here EEEEEWWWWWWww..... |
|
|
//It's true that puppies also have one useable surface. But they're much more absorbent and can be cleaned// |
|
|
Given cats' proclivity towards constant washing, might I suggest keeping one or two of those handy instead; by the time you need one it will have cleaned itself already, saving you the bother. |

Re: the original suggestion: while useful to the extent that when you come to the end of a Moebian toilet roll you never have to remember if you've used the other side, that roll is of a finite length. |
