That myth that you can't fold paper in half more than seven times? Turns out it's true(ish).
The man behind the Hydraulic Press Channel decided to test that theory by folding an A3 piece of paper in half seven times using his press and it turns out that paper really can't be folded in half seven times. Like, really, really can't because it shatters.
Yes, paper can shatter as it turns out. You learn something new every day.
Mythbusters once tackled the subject and it turns out if you have a large enough sheet and a steam roller you can get it up to 11 folds but that's not really realistic.
