In case you were wondering...

I found this useless trivia (unless you plan on being on Jeopardy or Millionaire) and thought I would share -
The pencil which most of us have used at one time or another has been around since at least 1565, when it was first described in a book about fossils.
The bottle cap was first invented by Willaim Painter in 1892 because beverages sealed with cork loss their fizz.
The paper clip idea came from Samuel B. Fay in 1867. In the 1890's the double oval design was first produced in England.
