If I understand correctly, the surface of a Möbius ring is mathematically speaking endless? Well, then. Take any length of toiletpaper, fashion a Möbius ring out of it and hey presto! Mathematical thriftyness galore! Enjoy!-- Ehrm, Sep 30 2005 I don't think you understand correctly. It is endless in the same way as a piece of string is endless once you have tied the ends together.-- st3f, Sep 30 2005 mind you it would certainly confuse the puppy.-- po, Sep 30 2005 You can't tie a puppy's ends together. That would be cruel.-- st3f, Sep 30 2005 This is a revolting idea.-- wagster, Sep 30 2005 Yes, puppies are so much softer. Plus, their mom licks them clean afterwards anyways.-- Trickytracks, Sep 30 2005 //If I understand correctly// You don't. Bone-- coprocephalous, Sep 30 2005 Better yet, after using your mobius strip of toilet paper, cut it down the middle with a pair of scissors and voila! you now have a ring twice as big and you can continue wiping.-- phundug, Oct 01 2005 [Phundug] understands [coprocephalous] doesn't.-- Ehrm, Oct 01 2005 I'm still stuck on this mental image of a mobius puppy that I keep getting. That's just odd... I'll have to get back to you.-- zigness, Oct 01 2005 That's one sick puppy.-- silverstormer, Oct 01 2005 random, halfbakery
