Between 17th and 18th of May, our group was present at Astrofest, an outreach event which aims to bring people of all ages closer to science. It took place in Parcul Crangasi from Bucharest, where we prepared space-themed hands-on activities.  We’ve welcome visitors with a guided virtual tour of the Solar System and a SpaceQuizz for those who wanted to test their knowledge and learn new information. Moreover, we presented an optical module prototype that was placed on the bottom of the Mediterranean Sea as a part of a neutrino detecting experiment.
