Problem - How did they build the first suspension bridge across the Niagra Falls in 1848?
Constraints - The waters are too rough; the narrowest point is a gorge that is 800m (244m) across. You need to get the first cable across but a boat crossing is not feasible; the distance is beyond the bow-and-arrow range.

The solution? A kite-flying competition!
The engineer, Charles Ellet Jr. announced a prize of $5 for the first person to fly a kite across the gorge. A young boy named Homan Walsh won the prize. His kit string was used to pull a cord across, which was followed by an iron-wire cable and then steel cables, until a configuration strong enough was put together for building a suspension bridge!
