5 minutes wind

Work realised using the anemometer, an instrument commonly used in meteorology to measure wind speed.
As is commonly the case in my work, I preferred empirical measurement to technological one and so I cut the anemometer’s data transmission cables and instead applied single strands of wool to each cup, which dipped in linseed oil carry, as they rotate, pushed by the wind, the charcoal powder lying on the paper. The anemometer is placed in the centre of the paper and exposed to the natural wind for 5 minutes. The circular pattern that emerges varies depending on the wind speed, its duration, any changes of course, interruptions or complete absence of propulsive thrust.
