How can we speak with a 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 stimulus. He confirms this with microscopic photographs of crystallised drops of water. Once the first photograph of a crystal of the river was taken, I invited Dr Mario Draiman, Professor of the Argentinean Homeopathic Association, Dra Alejandra Bustamante, Biologist in charge of National Water Investigation Institute, and Historian and Architect Marta Miras, specialised in the history of Rio de la Plata, to diagnose the actual state of Rio de la Plata and determine an homeopathic treatment according to its symptoms. The resulting diagnose was published and became a part of the exhibition. Dr Draiman prescribed Nux Vomica. A homeopathic dosing machine was created for which 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 for the time of the exhibition.
