How were the problems and promises of technology addressed in the heightened public awareness of environmental issues during the 1970s? ARARAT provides insight here. It was an exhibition arranged at Moderna Museet in Stockholm in 1976. Its goal was to inform visitors about the interconnections between humans, society, and the environment and, on the basis of such knowledge, empower people to seek less wasteful ways of life.To this end, the exhibition invitedvisitors to become actively involved in experiments and get acquainted with everyday technologies that were less expensive to make, easier to repair, and more transparent in terms of production and life cycle. Previous research on ARARAT has focused on its relevance for current practices in art and architecture. The presentarticle, by contrast, aims to situate ARARAT in contexts that are both more general and more specific than previous work has been able to show.The study argues, first, that ARARAT can be understood as pioneering the field of practical knowledge (“praktisk kunskap”) before it was more formally established around 1980 in Sweden; second, that the ARARAT undertaking amounted to a new kind of popular education(“folkbildning”) with its combination of science, politics, and hands-on experimentation; and, third, that the ARARAT project was a demonstration of the exhibition format as an environing mediumwhereby it actively took part in changing the environment by empowering the population in an era with significant collective challenges.
