Answer to Question 1

Gun cotton or nitrocellulose is made from cellulose fibers that have been treated with nitric acid. This material was, perhaps, the first plastic since it was a substantial modification of a natural polymer and it could be shaped or formed. It served as the model for several other acid-derived cellulose products such as rayon, celluloid and cellophane.

Answer to Question 2

One correct answer would be Celluloid, invented by James Wesley Hyatt in 1868 . However, the first truly synthetic plastic that was made to a specification was nylon. The work was sponsored by the DuPont Company

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa.
