The way the liquid passes through a vessel draws a direction in space, where pouring in, containing and pouring out are different stages in that directed understanding of a space. The relation between the inner space, the inside of the vessel, and the outer space is one of the central conceptions in corpus. The ordinary jug - we have been learned to recognize - is acting out from its inner body. it offers something to the surrounding when being activated by a body. This object is a shadow of this normative expectation and  draws the attention more into itself. It becomes an inverted space.
