We were discussing this today,  
folding a piece of paper in half more than seven times is said to be impossible because the paper reaches a thickness 128 times that of what is normally is, however, I seem to remember a test being done by scientists, metioned here perhaps, where they were able to exceed that supposed limit.

Anyone happen to know, or have the links?

Thanks,

I don’t know. You could always try searching the archives of Cecil’s columns, though. Who knows, you might find something useful like [this](http://www.straightdope.com/classics/a910705.html) .

I almost feel like Cecil, in a way, cheated in that column (please don’t smite me oh mighty Cecil). He wasn’t folding a piece of regular paper but rather a massive dropcloth.

I get the impression that the thickness does have to do with it, and all Cecil showed was that thinner sheets reach a “folded” limit sooner. I mean, how easily can you fold an 8.5x11 piece of paper versus the same size piece of cardboard? More folds in the paper, I’ll bet. Now try something thinner, for example, a Kimwipe®.They are pretty thin. I can imagine exceeding the paper by at least one fold.

I know nothing of physics or materials or anything like that, so I can’t begin to suggest WHY this might be, but just that that’s what I’ve observed…

Depends on how strong and thin the paper is. Thin paper is usually not all that strong and tear resistant. I have done this experiment with notebook paper and newspaper and both reach a folding limit fairly quickly because of the squaring inherent in the folding process and simply tear if folded one more time - granted I used the help of a vise to make the last fold.

It’s not possible to truly fold a piece of paper more than once.

Actually that’s not true, in fact it isn’t possible to truly fold a piece of paper at all.

I probably ought to explain now before the men in white suits arrive; when you attempt to fold two sheets of paper together, the inner one folds\* and the outer one _bends_ around the thickness of the inner, folded sheet.

\*It is all a question of degree, however, because the inner fold is only a very tight bend, but this is the nature of the problem; when you get up to the seventh fold, you’re tryng to fold what is effectively 64 sheets of paper together; the outer ones simply won’t fold because of the sheer thickness of paper between them - they just _bend_, the inner ones pucker and pull because the whole thing is constrained at the edges by previous folds.

A couple notes…  
Jack, there is no need to be condescending when you respond, the area I am posting from has banned my access to the archives (don’t ask me, I don’t know why), but left me access to the forums, it’s why I posted here first, yeesh.  
I also agree with some posts, Cecil was using an incredibly thin piece of plastic, note above, I was asking about paper.

So far as I recall Jack, and the boy at the grocery store always notes the difference, paper isn’t plastic.

Mange, way too in depth, but thanks for the information 😃

Last night, I folded a sheet of paper (newsprint), in half 8 times. After the 8th fold, the result was about 1 1/4 by 1 1/2 inches, and about an inch thick. So there ya’ go.
