Enya Burger. Residual Unit
MUR BRUT 35
23.5. – 10.8.2025

What’s in the air? What do we breathe?

For the 35th edition of MUR BRUT, Enya Burger captures the invisible – not as a snapshot, but as a slow-moving trace.
Within a square aluminium grid, sheets of pH-sensitive paper treated with Bromophenol Blue begin to change colour: a gradual process triggered by the air circulating through the car park.

The paper reacts to CO₂ and NO₂ – invisible residues of traffic. These gases form acids that lower the pH value, causing the deep blue hue to shift slowly towards a luminous yellow. Sealed areas remain unaffected, preserved in blue. Over time, an image emerges: a chemical imprint of the ambient air, a technical fossil.

The title Residual Unit speaks to what remains – the leftover, the measurable, the quietly persistent.
Burger installs a question that resonates both ecologically and politically: What’s in the air? This work resists control. It evolves over time. The car park becomes a chamber of resonance, of measurement – and the artwork, a sensitive membrane, documenting environmental transformation: visible, quiet, subversive.
