Billy Club from the Stanford Prison Experiment

1971: Standord University
Psychology Professor Philip Zimbardo ran a social experiment in the basement of the University where he hired 24 males who were randomly assigned the role of either a prisoner or guard. The guards were then told to quote, "You can create in the prisoners feelings of boredom, a sense of fear to some degree, you can create a notion of arbitrariness that their life is totally controlled by us", and were given khaki shirts and pants, as well as mirrored sunglasses and batons to enforce authority. During the experiment, the 'prisoners' decided to 'revolt', which in turn cause the guards to become more and more sadistic towards the guards, using fire extinguisher to punish them as well as removing matresses and forcing the prisoners to be naked.

This is one of the Billy Clubs that was carried by one of the mock guards and saw all of this happen. It wound up absorbing all of the sadistic power that the guards took out on the prisoners.
