When we approach a table we mainly pay attention to the table surface based upon a functionalistic definition of the term function. The surface derives its value from the role of supporting  other objects, and as a surface for social actions. This jug makes another agreement with the table: instead of standing on the surface, it has grabbed the edge. By this we are forced to look at the encounter between jug and table in a new way, which also makes us aware of the edge of the table and not only the surface. the table edge  becomes the most important part on the table for this unruly jug. The hierarchies that build up the way we look at things have, hopefully, by this been ‘deconstructed’. Through this  we might also see the table more as a whole object and part of the environment - not classified according to a normative hierarchic way of looking at things. Perhaps as we once understood it as small children when we also saw the underneath of the table.
