EPICS is a student association of scientific vulgarization which invites the public to show demonstrations in its school. This time, it’s the laboratory which comes to the public of the Cité des Sciences et de l’Industrie. It’s a course through the major themes of the actual research. This exhibition is thinking to awake everyone’s curiosity about stakes of science and maybe encourage some vocations. Each experience is in live and in interaction with people, far from the wrong cold image of the laboratory. Each stand we drew is movable, like the walls that can be assembled in many ways.
