Trashcans are uniform objects, spread according to density within  public space  and ‘open’ to ‘input’ from the public.

We could give this ‘input’ a twist by adding one more trashcan and providing both cans with a word. Both cans thus become opposite answers to a central question.

The throw-away gesture then becomes a little political or social act, provoking citizens to pause for a moment and consider how they think about certain topics.

These topics can be both light or heavy, trivial or deep.

The overall installation will result in a kind of ‘public opinion barometer’, having no official value but allowing a community to ‘read’ their trashcans and see how the people around them think or feel.

The installation could also be used by local polititians or concerned citizens as a tool to initiate micro referendums around certain issues.


Garbage cans could be placed at underground exits where used tickets could be disposed as ‘voting bills’

Can we materialize

public opinion?

by twisting the gesture of dumping trash into a small political or social act.

Trash becomes a medium to express individual opinions and feelings.

Trashcans become inofficial ‘opinion meters’ within the local neighborhood.
