In the installation cloud cores are produced with a laser printer and in-sucked into the Tropospheric Laboratory equipment. There they are counted with a TSI Particle Counter, and passed on into the spherical cloud chamber. If sufficient cloud core are present, the vacuum cleaner turns on for a few seconds. Within a second and out of the nothing a cloud is appearing inside the chamber, and so as came, it disappears again, as soon as the vacuum is cleaner out.
The cloud machine functions according to the adiabatic principle, which is the same principle how in the sky the clouds develop. The vacuum cleaner produces, by the sudden negative pressure, a drop of temperature in the cloud chamber. Within the laboratory sphere one single cloud core is then explored with the inside CC Scanner. This cloud core is picked out and passed on to the deccelerator for further examination.
Above the desktop of the Tropospheric Laboratory all medialised images and results of cloud core probing are situated: projections, in the monitor and pictures appear in an ?airglass magnifying glass". Underneath the desktop these pictures are generated - from material and physics, without computers.
At the same time many scann and visualization processess take place. Under a floating cloud core of the unusual size of an hen`s egg, a dipstick walks continuously under ago and investigates the state of suspension. On the other side of the lab-construction, a wheel, the ADM Filmbox, rotates and generates scenes under terrestrial conditions.
The TSI Particle Counter counts the amount of existent cloud cores inside the exhibition space. The result of measurement is printed. New cloud cores emerge from the printing process. In the moment where the result of measurement is printed, it is again falsified.
