Although nowadays we hardly ever part with mobile phones, our knowledge of them is rather limited. The project of a fictional touring exhibition is meant to draw the audience’s attention to the multitude of chemical elements used for the production of these devices and their geological origin. The exhibition is directed to mobile phone users, especially young people. It is supposed to be presented in large cities in Central Europe and in electronic waste disposal points. The key element of the exhibition is a place where visitors may leave their broken smartphones. There is also an interactive element: information boards placed on the container walls. Visitors can also see an installation made of combined national flags, which create individual flags for each chemical element.
