I understand your logic … and you’re right … there is a certain symmetry to the situation … and one could argue that there OUGHT to be no difference to the separation dynamics. HOWEVER … there is. REALLY!

Well … there is for me. I’ll hypothesize that it depends on the direction of the yank (upwards, downwards, outwards) and perhaps even the grip (whether the paper comes out of the top of your hand or the bottom of your hand as it heads back to the roll might be an issue … maybe even the choice of using your right or left hand makes a difference). I haven’t checked anything other than this: With MY grip and MY particular directional yank of the paper there is a clear and significant difference in the results for the two orientations of the paper. (All of this assumes a roll that can rotate freely … don’t even get me started on the solidly-in-place rolls in some public restrooms.)

So … has ANYONE tried the experiment? Report in! (And … notice that I have not yet said which orientation I use … only that I chose mine for a specific reason.)

I think the angle issue with tearing toilet paper off the roll is incorrect. If you think about it, the angle that you come off of the circle is always going to be the same, i.e. if you pull in any direction, you will always end up with equal friction on the spool.

I think it’s an illusion of sorts. Imagine a ball bearing rolling around a circle, or a discus being thrown by an olympian. When the release takes place, it’s always going to come off at a tangent to the circle.

So here’s my point. There isn’t a “tighter tangent” when pulling off toilet paper. If you pull from a different angle (trying to generate more friction somehow), all you’re going to do is change the release point on the roll — hence giving you the same exact amount of friction as if you had just torn it straight down while it was facing forward.

If I’m way off, feel free to pummel me.
