This paper describes our experiment as artists, concerned by scientific investigations. Considering Gibson’s ecology of perception, Maintier, Rybak, Zinke’s experiments and theories, we have also described our performances and cross studied what a practice of Art performance and scientific experimentation can tell each other and how they could most probably give their take one another. The main point is here the place of the body, its perceptions and actions, its breathing, its interactions with the environment, we develop the theme of the spiral as a fundamental pattern for our investigations as well as the turbulences of the air, around and exhaling from the body.
