Can we redefine the label “seriousness” when it is attributed to science? Do scientists have a sense of humor? Who would expect that science can actuallybe “hilarious”? The group”Science Reactors” has been created to answer just those questions. . The group consists of young scientists who participated and excelled in the Famelab Competition (an international competition organized by the British Council for the emergence of new talent in science communication), and has progressively been developed over the last three years in order to get knowledge out of the classrooms and laboratories, and develop the interest of young people for science and technology. The group also includes professionals from the field of Stand-up Comedy, who are in fact scientists. The idea is down to Helen Grammatikopoulou, who has been in charge of the “Science Society” program of the National Research Foundation since 1993.
