Hello every body today I am going to talk to you about how paper is made ? *. As we know , you read from it, write on it , draw on it , but you dont know how it's made . First of all paper is made from wood . First the wood is*Chopped into small pecies . Then chemicals are added to these small pecies . This changes them into very thic liquid . Next , This liquid is cleaned with another special kind of chemicals . After that , the liquid is put in " paper- making machine " . It's pressed and dried them to make paper . Finally , it's cut in deffirint sizes . And we use it in books , newspapers and paperbags .
