Why did the Philadelphia Exposition of 1876 fail?
assistant
The exposition was a failure because it was too small. It was only a few blocks long. The exposition had many attractions, including a huge Ferris wheel, a zoo, a roller coaster, a merry-go-round, a miniature train, and a lot of other interesting things. The exposition was meant to be a big event, but it was too small and didn't attract enough people.
