I uploaded a new video Escalator or Stairs.You have to see this.

  Escalator or Stairs Very cool
  Video attached See what clever engineering can do!!

  Watch what a group of engineers did using fun to get people to
  use a long staircase with a moving escalator right next to it...

  At first no one took the stairs almost 97% of the people took
  the escalator...

  Notice how scientists changed how people reacted to climbing a
  long stair case as first choice...66% more people took the
  stairs...^
