What is the Guinness Book of Origami Crane Records?

A sheet of paper can be folded in half up to 13 times.

In 2011, teachers and students at St. Mark's High School in Texas folded a 10,000-foot-long (nearly 4-kilometer) piece of toilet paper in half 13 times, and in order to complete the experiment, they placed the toilet paper in a corridor of more than 200 meters at the Massachusetts Institute of Technology and folded it collectively for more than four hours. After folding it in half 13 times, the toilet paper reached 8,192 layers.

Let's assume a sheet of paper is thick and start folding. The thickness is doubled with each fold.

So the thickness of the paper after folding n times is: 2 to the nth power.

If folded nine times, the thickness of the paper is about: about one centimeter.

Approximately, the area of the paper after being folded n times can be calculated.

Okay, let's get to the point.

It is possible that it will not move after folding seven times.

1.It's because the paper area is too small to fold.

2.The thickness is relatively large, and it is not easy to fold.

3.If you look closely, you can't "fold it in half" at all. I think that as the thickness of the paper increases, the longer the "corner" you fold back, the larger the "corner" will be, and when you fold it seven times, this "corner" will be very large, and it is impossible to "fold it in half".

Unless you tear the paper open. However, when you fold it, you don't even want to tear the paper, and you don't even want to break it. So it's not a lot of force.

If the force is strong enough, then it is because you do not have the idea of tearing the paper when you tear it, and the paper is not easy to break in the way of force. In addition you want to "fold in half" so, so this doesn't go down. (Actually, you can't "fold the paper" without tearing it).

Feel free to ask.

Using an endless corridor of toilet paper and MIT that is more than 2 miles long, a group of 15 MIT students and faculty set a new world record for paper folded in half in a row — 13 times, breaking the old record in 2002 — 12 times.

In fact, it can be folded 13 times, and the United States can fold it alone.

A piece of paper can be folded in half up to 100 times.

It can be folded nine times, no more than ten times, and of course there is no Guinness World Record.

The world record seems to be 7 times.

You can take a look at Kamiya's fold history, he seems to have folded fourteen times.

After the number of folds increased to 7 times, it is really difficult to increase the number of folds in half. But it also depends on personal skills, I used the paper torn out of the general magazine (taken from the middle page, in fact, the left and right pages are two pages in a row), and after folding it horizontally 8 times, I now fold it vertically 1 time, a total of 9 times. The previous answers are mostly theoretical calculations and the like, and I have not tried my own hands to answer others.
