The document summarizes an in-class experiment called the Angry Eye Experiment. Green-eyed students sat in the middle while blue-eyed students sat around the outside. The experiment aimed to show green-eyed students what it can be like for people of different ethnicities or orientations through stern treatment by the instructor of the green-eyed students. Several green-eyed students became upset by the experience, demonstrating how the experiment effectively conveyed its message about discrimination.
