Eli5: Why can you only fold a paper in half seven times, no matter the size ?
In: 4
It really wants to unfold itself. Each layer has some springiness and when you have 128 layers, it adds up.
However, Mythbusters managed to fold it [11 times](https://blog.thepapermillstore.com/seven-fold-limit-myth-fact-fiction/) using a steamroller and a forklift.
Also, there may be a limit where it becomes too thick to fold without ripping. Apparently that’s more than 7 though.
