The 2017 European Researchers' Night in Thessaloniki was organized by CERTH in Megaro Mousikis Thessalonikis. The organizers reserved a special spot for the MSCA fellows to enable them to promote their research and MSCA in general. This was a great experience since we had the opportunity to directly interact with the general public. It was really intriguing to explain research concepts without jargon, but at the same time this was a refreshing experience. The participation of the general public was overwhelming and we really enjoyed it. Thank you very much for the invitation, it was a pleasure. Hope to see you there again next year!
