The performer (artist himself) places a plastic cup of milk on the path of an automatic door of UCL Engineering building. The performer laterally runs in front of the automatic door and the sensor picks him up and the door re-opens narrowly missing crushing the plastic cup. The process continues until the inevitable happens and it is repeated by looping system. In the video, the performer should do whole of the process again and again.
