Folding paper in 1/2 13 times.

[RTicUL8]

Have you ever heard that it’s impossible to fold any piece of paper in half more than 7 times.
My daughter and I thought about that for a while and finally figured out how to fold a single piece of paper in half 13 times.

Any guesses on how we did it?

Get a life and dont post about it..... HAHAHAHA

I don't like guessing games.

no clue, please enlighten me

If you cut the paper in half, you can fold it 14 times.

lemme guess.

a piece of .003" paper folded 13 times would be 24.576" in thickness.

as long as the paper is wider/longer than it it "taller" it will be able to be folded.

because i don't have time to figure out the length*X at each fold, since the length around each fold (radius) increases, i will just wild-ass guess that DOUBLE the thickness (24.576) in order for the paper to be physically folded would need to be 33,554.43 feet long in one dimension, assuming the fold occurrs in the same direction. now if you used .003 as your thickness, and used the hypothetical minumum, you may have come up with 16777.216 feet....

its basically just a relationship with exponants.

I have a 30' roll of paper, when unrolled could easily be folded 13 times.

All that thinking/typing, and you still suck at teh funny.

you can fold a sheet as many times as you want. nobody said anything about not unfolding it each time. :moon:

a 30-foot roll of paper, .003" in thickness, folded in half, 13 times would be .0439" in length folded one way, and would be a little over 24" tall. It cannot be folded.

30 feet is 360 inches without being folded

fold it:
once = 180 inches
twice = 90
three times = 45..........
keep working the numbers

yuppiexj got it right.

We used a roll of cash register printer paper (about 250' X 3.5").

if she used paper that was .003" in thickness, and folded it half in one direction 11 times like in the picture, it would be 6.14" high.....

looks about right.

furthermore, those are 8" floor tiles, and since the finished fold-up is 24" long, that fold-up would measure 4096 feet long when it is unfolded.

OMG...my brain hurts. I've always thought that with a long enough piece of paper you could fold it more times, but to make a formula that describes it?!? :shiver:

its just basic math.

google exponants.

mathematically impossible.

if you had 250 feet of paper, .002 thick, and folded it in half in on direction, here are the dimensions after each fold:

0-250ft.-.002"
1-125ft.-.004"
2-
3-
4-31.25-.032"
5-
6-3.90625ft.---.128"
7-
8-.976---.512"
9-
10-.244ft.---2.048"
11-
12-.0610ft.---8.192in.
13-.0305ft (.336inch)----16.380" tall

there is no way you did this

it's not totally impossible.....if you can do the math and it checks out then it's possible.

its impossible to fold a piece of paper, 250ft in length, in half 13 times.

why would one havve so much paper

Actually, it will bulk-up more than the calculable sum. Paper folded in half without allowing the air to escape would include the trapped air.
