container, seawater/variable dimensions
A container, usually used for maritime transportation, has been sealed off and its content has been made inaccessible. Outside, two signs show some values: the composition of human blood and seawater. There is a tight connection between the compositions of two fluids but there is no way to know which is in the container.
My container is a kind of object that travels throughout time, more than through the space, as if it would remind the origins of life.
