Some of the things we love
the most were an accident
                         Coca-Cola
• In 1886, a pharmacist named
  John Pemberton was trying to
  create a tonic for people who
  were tired, nervous, or had
  sore teeth. In a large kettle, he
  mixed up a medicinal syrup. At
  first, he mixed it with cold
  water, and thought it was
  good. When he went back for
  more, his assistant has
  mistakenly mixed carbonated
  water in the second batch,
  which made it fizzy - just as it
  is today. Although it took a
  while for it to catch on (it cost
  Pemberton more to promote it
  than he made off it), eventually
  Coca-Cola became a beverage
  sold around the world.
             Implantable Pacemaker
•   The Pacemaker was an accident that actually
    saves lives today. Wilson Greatbatch was
    working on a device to record irregular
    heartbeats when he accidentally inserted a
    resistor of the wrong size. He noticed that the
    circuit pulsed, stopped, and pulsed again--
    just like a human heart. He worked with it for
    about two years and eventually made the first
    implantable pacemaker.
•    Before the implantable pacemaker was
    invented, people with irregular heartbeats
    had to control their pulse using a sometimes
    painful external device invented in 1952 by
    Paul Zoll. The external pacemaker was about
    the size of a small television, and
    administered life-saving jolts of electricity,
    which sometimes burned the skin.
•   Greatbatch later invented a corrosion-free
    lithium battery to power the pacemaker.
•   Yes, potato chips were a
    surprise invention, too. In 1853,
    George Crum, a chef at a resort
                                          Potato Chips
    in Saratoga, New York, made
    french-fried potatoes for a
    guest. The guest disapproved
    of the fries and sent them back,
    asking that they be sliced a little
    thinner. This happened twice,
    so the chef got a little miffed, so
    to get even, he sliced the
    potatoes very thin and fried
    them so that the guest would
    not be able to eat them with a
    fork. Well, it turned out that the
    guest was ecstatic about the
    crisp potatoes. Other diners
    began requesting them and
    they soon appeared on the
    menu as Saratoga Chips.
•   In the 1920s, Herman Lay, a
    traveling salesman, began
    selling the chips from the trunk
    of his car. Today, everyone's
    heard of Lays Potato Chips.
Penicillin
     • Penicillin is another
       famous example of a
       mistake turned good. In
       1928, scientist Alexander
       Fleming noticed that mold
       spores had contaminated
       one of the bacteria
       samples he had left by an
       open window. He noticed
       the mold was dissolving
       the harmful bacteria. And
       that's how we got
       penicillin, which helps
       people around the world
       recover from infections.
Velcro
   • The hook and loop fastener
     was invented in 1948 by
     Georges de Mestral, a Swiss
     engineer. The idea came to
     him after he took a close look
     at the seed pod burrs which
     kept sticking to his dog on their
     daily walk in the Alps. De
     Mestral named his invention
     "VELCRO" after the French
     words velours, meaning
     'velvet', and crochet, meaning
     'hook'.
          Chocolate Chip Cookies
• One of the most favorite
  cookies of all time was
  invented (accidentally) by Ruth
  Wakefield, an innkeeper. She
  was baking Butter Drop Do
  cookies one day, using a
  recipe that dated back to
  colonial times. Wanting
  chocolate cookies, she cut up
  a Nestlé chocolate bar and put
  the chunks in the batter. When
  she took them out of the oven,
  she expected to find chocolate-
  flavored cookies. Instead, what
  she got were butter cookies
  with gooey chocolate chips.
  Aren't we glad that happened?
                 Ice cream cones
• Two vendors had their stands
  beside each other at the 1904
  World’s Fair in St. Louis,
  Missouri. One of the vendors
  was selling a wafer-thin
  Persian waffle called
  zalabia. The other vendor was
  selling ice cream. It got so hot
  during the fair that the vendors
  ran out of dishes for the Ice
  cream. The waffle vendor
  rolled a waffle into a cone
  shape he topped it with some
  of his neighbor's ice
  cream. The ice cream cone
  was a total hit at the world’s
  fair.
• Yellow sticky notes (Post-it
                               Post-it notes
  Notes) were about to be
  invented in 1968 when a 3M
  researcher tried to improve
  adhesive tape. He came up
  with a semi-sticky adhesive -
  not suitable for tape, but he
  thought it could have a use for
  something else, he just didn't
  know what.
• A few years later, another 3M
  scientist was needing a way to
  keep his bookmarks from
  falling out of his hymnal while
  he sang with his church
  choir. He needed something
  that would stick without being
  permanent. He remembered
  the weak glue his colleague
  had accidentally created 4
  years before. In 1980 the Post-
  it Note was created.
•   Who didn’t have a Slinky when
    they were a kid? If you didn't have
    one, I'm sure you at least played
    with one at some time. Slinkies
    are part of modern Americana.            Slinky
•   The Slinky was invented by
    accident. In the early 1940s, a
    spring fell off the desk of a marine
    engineer named Richard James. It
    tumbled end over end across the
    floor. This new invention hit toy
    store shelves in 1948, and the rest
    is history.
•   To manufacture his new creation,
    Richard James designed and
    engineered machines to transform
    80 feet of wire into a 2 1/2 inch tall
    stack of 98 coils. Boom, he had a
    Slinky making machine. Today, the
    Hollidaysburg, PA based factory
    churns out 3 million to 4 million
    Slinkies a year. Mrs. James, who
    came up with the name "Slinky"
    has been chief executive officer
    since 1960.
