New Research Watch What Happens When You Use A Hydraulic-Press To Try To Fold A Piece Of Paper 7 Times


How many times can you fold a piece of paper? There’s a myth that you cannot fold it perfectly in half extra than eight times, but given a large enough piece of paper, and with powerful hydraulic equipment, you could fold a piece of paper as a lot of times as you wanted.
The Hydraulic Press Channel on YouTube determined to use this exact type of equipment to fold a piece of A3-sized paper seven times, amazing that is considerably difficult to do using just human hands. After attempting to fold it for the seventh time, though, it appears to reason the paper to explode, transform the remnants into brittle, fractured pieces.
So why did the paper appear to explode? Well, one option is that it wasn’t the paper at all.
For any bit of paper, after the opening fold, it doubles in thickness. Another fold, and it quadruples in thickness. By the seventh fold, it would have turn into 128 times thicker than it was at first. This is known as exponential growth, and explains why a piece of ordinary paper folded 23 times would be a kilometer (0.62 miles) thick. Forty-two folds will stretch out to the Moon, and 103 folds will get bigger beyond the observable universe.
At the same time, every additional fold is harder to make as it require rapidly increasing amounts of pressure to squash the increasingly thicker bit of paper. On the seventh fold, the hydraulic press is using incredible pressures in order to attain its goal. When the fold breaks the piece of paper, the press suddenly juts forwards, create the explosion noise.

A few years back, the Mythbusters team successfully folded a a great deal larger bit of paper a total of 11 times with the aid of a steamroller – and yet, there was no explosion. This seems to suggest that the hydraulic press is to blame for the bang noise in the now-viral YouTube video.
However, another option is that the "explosion" is down to the crystals of calcium carbonate found within the paper, a common part added during the manufacturing procedure. The stress put on the seventh fold dense these rigid crystals to the point of sudden collapse, which led to the catastrophic breakdown of the paper.
