Re: Why does folding paper make it stronger?

OK, here goes:

A piece of paper is of a certain strength. If you fold paper, you do not
increase the strength of the paper, but by there being two sheets (through
folding), each can hold at least the same amount and so the folded sheet
can hold more.

This happens however many times you fold the sheet or if you add more sheets.

The top sheet will hold as much as it can, if that is too much for it,
instead of tearing, the next sheet down will try to hold it.
