Paper is made by pulping wood chips or recycled paper, adding water, and pressing the mixture into sheets. The sheets are then dried and smoothed, resulting in thin, flexible, and writable material.
Over the years, paper has become an indispensable product in the daily lives of many people, like newspapers, toilet paper, books, magazines and works of art. But, the history of paper started many years ago. Even before paper came into existence, people used caves and other natural surfaces to engrave and paint symbols, like in the caves of Lascaux in France.
