Stories are developed in collective processes. They are pieced together from various perspectives, desires, and fears. In the Puppet Theater Workshop for children and youth offered by Florian Gass and Mirja Reuter an additional contributing factor is the wish to determine or interpret the course of events oneself. Taking place in conjunction with the 11th Berlin Biennale at the ExRotaprint complex, the workshop allows participating children and youth to construct puppets and stage sets as well as apparatuses to project shadows and images as well as fictions and illusions. A movable structure made of scenic components and screens provides a setting for new narratives to unfold on a daily basis. It also facilitates experimental play with the acts showing and concealing, since the participants enact the plays with their own bodies, voices, and self-built puppets.
