Imagine a not so distant future where rogue nation states are harnessing human biomaterials to create explosives. This work attempts to produce ammonium nitrate from breast milk. Using a process called deamination to extract ammonia from breast milk, the work interrogates popular perceptions around ‘good’ and ‘bad’ material. Staged as a failed experiment, the work draws attention to the constraining logic of utility that frames scientific research. Milk donated by The Human Milk Bank, Irvinestown, Co Fermanagh.
