Frackbox was designed to be covertly placed at the intersections between Pennsylvanian citizens’ homes and nearby fracking sites in the United States. These structures (which at first glance appear to be the standard road-side US mailbox) contain a kit which monitors air pollutants and volatile organic compounds. Members of the Pennsylvanian community, working with the kits in 2014, were able to collect enough evidence to unlock an additional $1.6 million of state funding towards further environmental monitoring.
