‘Five Day Locker Piece’ (April 26-30, 1971) by Chris Burden.
At the University of California, Irvine, Chris Burden locked himself in Locker Number 5 for five consecutive days. He rigged the locker above him to hold five gallons of bottled water, while the locker below him held an empty five gallon bottle. His then-wife, Barbara, slept on the floor in front of the locker some nights, “in case I really flipped out or something,” the artist wrote in a 1975 untitled statement.
