Paper Clips

• The paper clips was invented in the year 1900 by
  a man from Norway named Johann Vaaler.

  together with pins, or spring operated devices.

  binding together against the Nazis.

Scotch Tape

• Scotch tape was invented in 1925 by a company in
  Minnesota.
• (later known as 3M)
• Originally, tape was used to separate the
  different colors on cars as they were painted,
  but soon it was refined to have sticky glue all
  over the back and was used by painters,
  carpenters, and eventually almost everyone.

• Do you remember having to dip your pen into ink
  every time you wanted to write something?
• Oh thats right, we never had to do that, because
  of the invention of the ballpoint pen.

Ballpoint Pens

• The ballpoint pen replaced dipping pens into ink
  in 1943.
• The Biro Brothers came up with the idea to put
  the ink inside of the pen and in 1944 were used
  by British Air Force pilots because they would
  work at high altitudes, unlike regular ink pens.
