I have read about this study before and I saw the video a long time ago. I seen it differently today, watching the looks in those children's eyes was heart-wrenching. My youngest son took part in a 1-day experiment when he was in first grade. The teacher was teaching about Martin Luther King Jr. and she wanted to show the class what it was like in a schoolroom during segregation, that was the day he learned that having a white dad did not make him white, his mother if Filipina, he along with half of his class had to sit on the floor against the wall and were not allowed to talk as the other kids had their lessons. His teacher said she was in tears because of the experiment, but it helped my son understand what many people continue to go through on a daily basis.
