Lateral Thinking Puzzles
  • The term 'lateral thinking' was coined by Edward
    de Bono to denote a problem-solving style that
    involves looking at the given situation from
    unexpected angles. Sometimes a problem seems
    difficult or insoluble because our assumptions
    about it are wrong.

Lateral Thinking Puzzles
Classic Example
  • The Surgeon... A father and his son are involved
    in a car accident, as a result of which the
    father is very badly injured and his son is
    rushed to hospital for emergency surgery. 
    However, the surgeon takes one look at the boy
    and says "I cannot operate on him". When asked
    why, the surgeon replies "Because he's my
    son...".
  • How could this be the case?
  • Answer The surgeon is the boy's mother...

Edward De Bono's Six Thinking Hats
  • Blue Hat Thinking Managing the thinking
  • White Hat Thinking Just the facts 
  • Green Hat Thinking Creativity. Ideas.
    Possibilities
  • Yellow Hat Thinking Benefits. Pluses
  • Black Hat Thinking Difficulties. Problems
  • Red Hat Thinking Feelings. Gut Instinct.

Puzzle 1
  • Bottleneck 
  • Put a coin in a bottle and then stop the opening
    with a cork. How can you get the coin out of the

Puzzle 3
  • Can You Explain?
  • Question How can you throw a ball as hard as you

Puzzle 4
  • Can You Explain?
  • Question Two students are sitting on opposite
    sides of the same desk. There is nothing in
    between them but the desk. Why can't they see
    each other?
  • Answer The two students have their backs to
    each other.

Puzzle 6
  • Coast to Coast  
  • Train A and train B are crossing the country,
    from coast to coast, over 3,000 miles of railroad
    track. Train A is going from east to west at 80
    miles per hour, and Train B is going from west to
    east at 90 miles per hour. Which train will be
    closer to the west coast when they meet? (Hint
    You dont have to do any math to get the answer.
    Just use your head!)

14
Puzzle 6
  • Answer When the trains meet, they will be at
    exactly the same point. Therefore, they will each
    be the same distance from the west coast.

Puzzle 7
  • Crossing the River 
  • Jake was standing on one side of the river, and
    his dog Scruffy was standing on the other side.
    "Come on Scruffy, come, boy!" shouted Jake.
    Scruffy crossed the river, ran to Jake, and got a
    treat for being a good dog. The amazing thing was
    that Scruffy didn't even get wet! How did Scruffy
    do that?

16
Puzzle 7
  • Possible Answers
  • The river was frozen.
  • There was a bridge over the river, and Scruffy
    crossed the bridge.

    cool himself. As a result, much of the salt
    dissolved into the water, ruining the salt for
    Amir but improving matters for the donkey because
    his load became much lighter. Amir tried to get
    to the market on the following days, but the
    donkey always ruined the salt. Finally, Amir
    decided to teach the donkey a lesson. He once
    again set out with the donkey and the two sacks.

  • If none of the following statements are true, who
    can we conclude broke the vase?Mike Sally

    broke the vase.April Tom, Mike I could not
    have broken the vase.Chris I did not break the

    innocent.

49
Puzzle 31
  • Chris. If the statement "I did not break the
    vase" is definitely false, we can be certain that
    Chris broke the vase. Statements that some
    individuals "couldn't have" broken the vase only
    mean that these individuals could have broken the
    vase, but do not guarantee that they did. Jim's
    statement that "Tom is innocent" is too vague. We
    know that Tom is not innocent, but this does not
    assure us that he broke the vase.
