1893 Worlds Fair (Columbian Exhibition): What Really Went on There?

In 1893 Chicago was chosen to host the Word's Fair, which was a big deal at the time, unlike today when nobody gives a sh*t.
The Fair was a lot of fun despite there being a serial killer, human beings on display, and a horrible, deadly fire that killed 400 people. There was the first Ferris Wheel, Cracker Jacks, and Pabst Blue Ribbon beer!
