Here's what happens if you ignore the mathematical limit and fold it again with a hydraulic press: https://www.youtube.com/watch?v=KuG_CeEZV6w https://www.yout

  What's shown is not a "folding" action, which is reversible, but a "mixing" action. The fabled Japanese sword steels are produced with a similar non-reversible mixing action, increasing the carbon content of the alloy each time.

    Just because the hype around katanas is a pet peeve of mine: although Japanese swords are better known for this technique it's not exclusive to Japan by far. See https://en.wikipedia.org/wiki/Pattern_welding https://en.wikipedia.org/wiki/Pattern_welding

  We can debate the semantics but that's not "paper" anymore.

  Oh my, that Hydraulic Press Channel is quite something! And I thought the Will It Blend guy was crazy...

    I prefer the power hammer [0] over the press, it's a whole different level of crazy. The amount of energy it releases is downright frightening. [0] https://www.youtube.com/watch?v=mhRNO-MpEf4 https://www.youtube.com/watch?v=mhRNO-MpEf4

  You'd find that the n-folded paper is both too tick and to narrow to achieve a n+1 fold. You could still put it in the hydraulic press and apply plenty of force with it, but the points where you apply the force will be too clumped together; the press would not fold the paper, just squeeze it really, really hard, and probably deform it or tear it apart at places.
