  • But this slideshow is about a different kind of
    Hidden Mickey. The kind that hide under the
    Magic Kingdom.

19
  • Do you ever wonder how the characters at Disney
    World parks seem to appear as if by, well, magic?
    There is a story behind that.

20
  • One day while strolling through Disneyland, Walt
    Disney saw a Frontierland cowboy walking through
    Tomorrowland. He then decided that for Disney
    World that some needs would have to be hidden.

21
  • Trash, costume characters, etc. had to be out of
    sight.

22
  • To do this, each area, section, or ride was first
    planned out in story boards. Then, the Imagineers
    constructed models, and viewed them in every
    angle.

23
  • To hide the utilities, underground tunnels were
    put in for Walt Disney World. Disney built a nine
    acre network of tunnels so Cast Members would be
    able to move around out of the public view!

26
  • The park was built over a huge underground
    complex. Disney did not dig tunnels under the
    Magic Kingdom. The corridors were built at ground
    level.

27
  • The tunnel complex consists of 15 foot high
    walkways, meeting rooms, computer rooms, etc.
    with all having exposed utilities (it somewhat
    resembled a parking garage).

28
  • The tunnel complex originates from the castle and
    spreads out like spokes from a wheel to the other
    lands. In fact, the bottom two floors of the
    castle consists of the tunnel complex.

29
  • The soil from the excavation of the Seven Seas
    Lagoon, around 5 million square feet, was heaped
    over this complex. Additionally, sand from the
    Seven Seas Lagoon excavation was used to line the
    Lagoon, Bay Lake and many other bodies of water.

30
  • The Seven Seas Lagoon is Walt Disney World's
    man-made lake. Although Bay Lake is a natural
    lake, soil from its bottom was also used to cover
    the complex

31
  • Thus, the pseudo-tunnel system was born. Another
    name for the system of tunnels under the Magic
    Kingdom is Utilidors, even though the internal
    Walt Disney World phone book does use the term
    "tunnels." Utilidor stands for utility corridor.

34
  • No guests under 16 is allowed in the tunnel
    system because it would bother children, seeing
    two Goofys passing each other, Mickey without a
    head, seeing Minnie eating with Snow White, and
    ruin the magic.

35
  • Walt Disney World guests do not realize the
    existence of this underground complex because
    they enter from the monorail. But, the tunnel
    system is considered by Cast Members as the 1st
    floor, and not really a tunnel system.

36
  • The entire Magic Kingdom is technically on the
    second and third floors. While most areas are on
    the 2nd floor, Fantasyland is on the 3rd floor.
    If you notice while in the park you will see how
    Fantasyland and the castle are higher.

  • The tunnel has the costumes for all the
    characters and themed areas hanging for the Cast
    Members.

39
  • With 1.2 millon pieces of clothing, it is the
    largest operating wordrobe department in the
    world. Each Cast Member has 3 costumes. The one
    s/he is wearing, on on the rack and one in the
    wash (or bag as the Cast Members call it).

40
  • From the center, an elevator with a special key,
    goes to the famous "secret" apartment inside the
    castle.

41
  • From various sites inside the octagonal tunnel,
    stairs and elevators go up to points "On Stage."

42

43
  • Usually, elevators go to kitchens, and stairs go
    right out into the park or into a shop. The next
    time you see an unmarked door remember the tunnel
    system.

44
  • There are many hidden entrances throughout the
    park. As an example in Main Street there is a
    door that leads to the back of the bank where
    Cast Members get their checks.

45
  • There is a door besides the carousel. Walk
    through the door and go down some stairs and you
    are in the utilidors.

46
  • Gasoline powered vehicles are not allowed in the
    tunnels for safety reasons.

47
  • Normally, the only exception is the Brinks truck
    which collects money from Cash Control.

48
  • My most memorable joke took place in the
    utilidors, which are simply incredible. We were
    standing in the hallway, below a big 15"-18" tube
    and our guide stopped us and said "ok everybody
    quiet, listen" and we heard something flow
    through the tubes and our guide then explained
    that the tube system above us was actually used
    to transport money from stores and kiosks
    throught the park to a central "Collection room".
    afterwards he explained that it was the trash
    collection system that whisked trash to a
    collection room at (I believe) 35 mph.

49
  • Cash Control is located underneath Pinocchio's
    Village Haus. It never closes. Ambulances are
    allowed to drive in the tunnel, but only in cases
    of extreme emergency.

50
  • As an aside, Epcot and the Disney Studios do not
    have tunnels like the Magic Kingdom does.

51
  • Unless the person is a Cast Member or on the tour
    they are not allowed in.

Geodesic Domes
  • A geodesic dome is an almost spherical structure
    based on a network of struts arranged on great
    circles (geodesics) lying approximately on the
    surface of a sphere.

59
Geodesic Domes
  • The geodesics intersect to form triangular
    elements that have local triangular rigidity and
    yet also distribute the stress across the entire
    structure.

60
Geodesic Domes
  • It is the only man-made structure that gets
    proportionally stronger as it increases in size.

61
Geodesic Domes
  • When completed to form a full sphere, it is known
    as a geodesic sphere.

62
Geodesic Domes
The Montreal Biosphère, formely the American
Pavilion of Expo 67, by R. Buckminster Fuller
63
Geodesic Domes
  • The first dome that could be called "geodesic" in
    every respect was designed just after WWI by
    Walter Bauersfeld, chief engineer of the Carl
    Zeiss optical company, for a planetarium to house
    his new planetarium projector.

64
Geodesic Domes
  • The dome was patented, and constructed on the
    roof of the Zeiss plant in Germany and opened to
    the public in 1922.

65
Geodesic Domes
  • Some thirty years later R. Buckminster Fuller
    apparently came up with the idea independently
    and named the dome "geodesic."

66
Geodesic Domes
  • Although Fuller cannot be said to be the
    inventor, he exploited and developed the idea,
    receiving a U.S. patent.

67
Geodesic Domes
  • The geodesic dome appealed to Fuller because it
    was extremely strong for its weight, its
    "omnitriangulated" surface provided an inherently
    stable structure, and because a sphere encloses
    the greatest volume for the least surface area.
    Fuller had hopes that the geodesic dome would
    help address the postwar housing crisis.

68
Geodesic Domes
  • From an engineering perspective geodesic domes
    are far superior to traditional, right-angle
    post-and-beam constructions. Traditional
    constructions are a far less efficient use of
    materials, are far heavier, are less stable, and
    rely on gravity to stand up.

69
Geodesic Domes
  • However, there are also some notable drawbacks to
    geodesic constructions as well. Although
    extremely strong, domes react to external
    stresses in ways that confound traditional
    engineering.

70
Geodesic Domes
  • Some structures will retain their shape and
    contract evenly when stressed on the outside, and
    some don't.

71
Geodesic Domes
  • For example, a dome built at Princeton, New
    Jersey was hit by a snowplow. The stress was
    transmitted through the structure, and popped out
    struts on the opposite side.

72
Geodesic Domes
  • The dome was successfully adopted for specialized
    industrial use, such as the 1958 Union Tank Car
    Company dome near Baton Rouge, Louisiana and
    specialty buildings like the Henry Kaiser dome,
    auditoriums, weather observatories, and storage
    facilities.

73
Geodesic Domes
  • The dome was introduced to a wider audience at
    Expo '67 the Montreal, Canada World's Fair as
    part of the American Pavilion.

74
Geodesic Domes
  • A dome was constructed at the South Pole in 1975
    where its resistance to snow and wind loads is
    important.
