Papers are like an ant. They are super weak when they are alone. However, they can be sill hard when they are many together with each other. This video will describe and show you one of the secrets of science that is a Paper turned to a very strong object as like as solid stone. Some tissue paper was taken into Pressing Die, so drops of methanol were used to make the paper wet. Then the paper is pressed by a hydraulic press at 60-kilonewton force. This huge amount of force brings the paper molecule close enough to make a tight bonding resulting in a very hard object like solid stone. This hydraulic pressed toilet paper is the hardest paper in the world. Vickers hardness test was done and the hardness of this paper made solid stone was very close to still. This might be the hardest paper ever so-called paper made a pellet. From the result, it is clear that hydraulic press action can make some amazing things that are behind our imagination, sometimes reality and science do not match together.
