For my 4th year degree project I made an artificial rain machine which induces corrosion on sample material in order to visualise precipitation (rain) chemistry data of major cities around the world. RUST. simulates precipitation chemistry by varying acidity, salinity and volume in accordance to meteorological data from the World Data Centre for Precipitation Chemistry. In doing so, RUST. challenges the conventional perception of place identity by expressing places through quantifiable geo-chemistry data as opposed to qualitative social-cultural values such as culture, heritage or history.

The rain machine is controlled through a geographical interface. Users can choose a city on the map by pressing one of twenty buttons, this controls the acidity, salinity and duration in accordance with the annual rainfall. The rain is cycled continuously to rust the steel houses throughout the duration of the cycle.


This machine was designed and fabricated under 5 different subsystems: static (structural), dynamic (water), electronic, software and chemical. Moreover, there was a heavy visual focus on the aesthetic and theatrical element of the rain resulting in many clear components such as the main body and shower-head as well as the curved anodised aluminium chassis.
