In this episode, the facilitator sets up the space with chairs representing key “actors” of air pollution, pollutants, odour, filters, flammable gases, the polluted environment, and hazy air. The facilitator frames the exercise as an imaginary conference in which these elements are not abstract concepts but active delegates who have gathered with one goal: to “suffocate” the residents of Eleusis. Participants are invited to step into the role of these delegates and speak from their perspective, as if they are experts arriving with years of research, scientific authority, and prepared “papers.” Through this role-play frame, the facilitator encourages participants to articulate how each factor operates, how they relate to one another (e.g., filters versus pollutants, odour as a constant presence, flammable gases as danger, hazy air as a lived condition), and how together they create an oppressive atmosphere, turning technical realities into a vivid, collective narrative grounded in everyday experience.
