The camera pans up from a ground-level view of a wall with clear plastic pipes to a view through a large window. Three or four people are gathered and gazing up at the pipes, which carry a dark substance suspended in liquid. The pipes angle horizontally and then drop vertically. The pipes are attached to the wall, which is white with rounded corners. A control panel with lights is near the pipes. The camera pans up, revealing the building's interior, including ceiling fixtures and ductwork. Through the window, a street with buildings and trees is visible. A circular light fixture hangs in the foreground.
