After a long year of hard working PONYS had the pleasure to organize a special event that took place on the department’s rooftop. This our typical event falls on the June’s last two weeks or the first one of July to advertise the group activities and to increase the members unit. During the aperitif, as our tradition, we sell humorous scientific and self-producted t-shirts. On that day we wish even to give students, researchers and professors some relaxing hours drinking fresh beverages and listening to good music. The music accompaniment this year has been left to the neapolitan rockband Hyena Ridens.
