Before airplanes were invented, a suspension bridge was being planned to span the gorge near Niagara Falls. There was no way a boat could carry the necessary suspension cables across the violent water, and the bridge could not be built until the cables spanned the river. One day the builders staged a contest open to the public that solved their problem. The contest was won by a young boy. Shortly thereafter, the cables spanned the water. What countries did they stage and how did they use it to solve their problem?
