The European Researchers´ Night (ERN) in Slovakia is the biggest science popularisation event for broad audience taking place every year. Since 2007 it is established science event that brings interactive programme and science and innovation closer to citizens and ordinary people. The ERN traditionally takes place in September in unusual places - in shopping centres and public spaces. Innovative formats, direct interactions with scientists and informal setting of the project involves hundreds of researchers and it attracts thousands of visitors every year. Science show within the ERN takes place in unusual places – shopping centres and an old market hall - where it also attracts random visitors and people who normally would not be interested in the topic. Through an interactive programme it invites visitors to participate in science experiments, demonstrations, discussions and lectures and provides an opportunity for dialogue and exchange between science community and the Slovak society. The ERN focuses on young people and students, and it presents them science, and opportunities it provides thus motivating them to embark on research career. The science festival appeals to young audience and showcases research in an unconventional and entertaining way.
