Measures: various

Set-up and Execution:
Eight automatic fire extinguishers are emptied, filled with red paint, and sealed under 6 bar of pressure. They are all hung by steel cables, at the same height and equidistant from one another, from the ceiling of a large room with many windows. Magnifying glasses attached to telescopic poles are positioned under the heat-sensitive ampules. Two full-length mirrors per fire extinguisher are positioned so that they reflect the light from the windows onto the magnifying glasses.

If enough sun shines through the windows, the fire extinguishers will be triggered and will start spraying their contents. On the floor, red circles will appear.
