A small entryway leading to a bathroom stall-sized room was built in the gallery. The only objects in the white room where a porcelain drain set in the floor and the lights attached to the ceiling. As the viewer enters the room, a motion sensor is activated, which after one minute turns off the floodlights that light the space and turns on a fluorescent black light, which reveals a glowing ink, used to test for the contamination of liquids, splattered on the floor and walls.
