the young audience in the field during recess time
with the participants, and their rockets
First the were rockers flying in the air. Then, the sounds of people shouting and clapping. After that, people were seen running here and there on the field. Nothing serious though, just a bunch of happy students taking part in rockets making competition at the school field.
Everyone looked happy. Lucky people, when I was in school I had nothing else to do but study all the time (exaggeration).
