The video is taken from publicly available sex education materials with opening and closing credits and chapter headings/inscriptions removed, displayed on a 5-inch plasma screen fitted on the wall 1.3m from the floor with speakers on 2 sides. A sensor is installed to keep audiences at a 5-metre distance: the video image will be disrupted and disappear if an audience member is detected crossing the 5-metre restriction; the image is only clear outside the sensing area. The sensor and the computer connecting to the screen are placed on an exposed shelf below the screen, about 10cm high from the floor.

Length of video: 14 minutes 42 seconds
