The "Dissabtes de la Física" included an experimental part with the students, in which they could expereince the properties of the superconducting materials, such as the levitating phenomena, or the zero resistance to electrical current. Some members of the SUMAN group were in charge of these experiments (Dr. Xavier Granados, Dra. Cornelia Pop, Dr. Joffre Gutiérrez, Dr. Pedro Barosco and Dr. Max Sieger).
