How can we speak with an ever changing river? This work intended to modify the way we communicate with the main aquatic landscape of the city of Buenos Aires. First, to understand the current state of the river, the work borrowed a technique by Masaru Emoto, who claims water has memory and responds to negative or positive stimuli. He confirms this theory with microscopic photographs of crystallised water drops. Once the first photograph of a crystal of the river was taken, I invited Dr. Mario Draiman, Professor of the 'Argentinean Homeopathic Association', Dr. Alejandra Bustamante, Biologist in charge of 'National Water Investigation Institute', and Historian and Architect Marta Miras, specialised in the history of the Rio de la Plata, to diagnose the actual state of this river and determine an homeopathic treatment according to its symptoms. The resulting diagnosis was published and became part of the exhibition. Dr. Draiman prescribed Nux Vomica. A homeopathic dosing machine was created that it slowly supplied homeopathy into the river. The treatment’s effect on the River was followed by re-taking a crystal photo once a week, which was supervised by Dr. Mario Draiman during the exhibition.
