Waldinhalierbar (forest inhalation bar) was a temporary smoking or more specifically a vapour room. In a quiet and ceremonial atmosphere specially developed vapour liquids where provided in inhalators produced by pavillon_35. The visitors where invited to follow a small ritus which included a drink and a small forest-biscuit. Our main questions with this project where how different forms of a social spaces can change the way we communicate or what we exchange and about the role of social rituals in a world of self-optimization.
