During Rio’s Carnival both tourists and locals always face the same problem when visiting a street “bloco” (parade party): where to piss? The lack of public toilets makes that the city becomes impregnated with urine for days. The situation became so serious that last year the local authorities decided to detain people who were caught urinating out in the open. Afro Reggae, an NGO and musical group linked to the “favela” culture, asked JWT Sao Paulo to solve this problem in a more friendly way. The result is symbolic, but distinctive: ‘Electric Pee,’ a urinal turning pee into electric energy through a hydro-electric dynamo. The urinal working as a battery fed right into Afro Reggae’s Trio Eléctrico, parading down the street along the famous Ipanema Beach.
