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?

The builders of the bridge were inspired to offer a prize to the first person to fly a kite from the American side to the Canadian side. Once the kite string made the crossing, a heavier cord was tied to this string and it was pulled across. This process continued in succession using heavier cords and ropes until the first cable spanned the river.
