I read the book “The Man Who Walked Between Towers” by Mordicai Gerstein to my kindergarten class.  It is the story of Philippe Petit, a tight rope walker, who walked between the Twin Towers in 1974.  I read the story first.  (Warning, I tear-up at the end every time. . .)
Then I showed the children video of Philippe actually walking a tightrope.  They totally gasped with awe!  Today they asked if we could write a letter to Philippe and inquire about how he walked on a rope between two skyscrapers.   We talked about people who trained to do this kind of work -that it took Philippe years upon years of hard daily practice to do it.
