The visitor can now continue walking(carrying the bag) through the exhibition. As the visitor reaches the top floor, he/she should empty the bag into the pipe-system. The spot, where to unload the bag, was marked by two signs, which were also used as a hanging-system for empty bags.

This installation brings back the element of sound – generally associated with the act of labor – into the factory by using the pipe-system together with the indirect (that is to say: less obvious) labor of the visitor. It is a irregular sound of bumping stones and sliding sand , creating a surreal atmosphere for the other visitors still approaching the top floors of the building.
The visitor was not able to contextualize the sound immediately, which is actually produced by other visitors.
The secret reveals reaching the top.
On one hand I find it very important to include the visitor into the reenactment, which they don't know about in the first place. On the other hand I want to re-implement a very important part of the character of a factory: its sound.
