Students from the third grade of the 201st Primary School St St Kiril and Metodiy visited the Sofia Science Festival in Sofia Tech Park. There they were able to create luminous 3D cards, make their racing car, make Leonardo's flying machine and learn how it helped create modern aircraft, as well as curious facts about the discoverer's life and achievements. They then watched many demonstrations of different fields of science and took part in many interesting experiments. Briefly, they had a rich and exciting day.
