Consider the flying toilet. The term comes from the Kibera slum in Nairobi, Kenya. Within the slum, there is often less than one latrine per 50 shacks, with each 12-foot by 12-foot shack containing, on average, eight people. Kibera sits on government land that never fully transferred legally to its pre-independence residents, and, as such, the government treats residents as squatters with no right or entitlement to legal, social, or economic protection. A complete lack of governmental presence within the slum means that at night, with no street lights and collections of roving thugs (and, at times, predatory policemen looking for a shakedown), using toilets can become dangerous. In response, shacks stock up on plastic bags, defecate or urinate into them after dark, and fling them from their windows out into the streets to bake in the morning sun.
