The workshop proposes a playful guide into the materials, connected to different types of infrastructures. Participants are proposed to make imaginary and existing small models, and try to find overlappings, conflicts and ways to (dis)connect them. During the laboratory we will look at the interweaving at different scales: through modeling, tactility and motor inventiveness; adjacency through endoscopic observation; roughness through a microscope; through using different materials connected to infrastructures themselves.
