In 1893, a world's fair was held in Chicago to celebrate the four hundredth anniversary of Christopher Columbus's discovery of America. To say it was big would be a huge understatement. It was so big it spilled into Lake Michigan, and the Ferris wheel was six stories taller than Chicago's tallest skyscraper.
