Singing. Oh nonononono this was way worse than that squeaking sound that balloon was making. Kevin put his elbows on the desk and placed his fingers in his ears as the Professor passed by him while singing OUT LOUD and then he heard a POP and he looked up to see that the balloon had exploded.

Good.

Taking his fingers out of his ears when the class finally began, Kevin raised an eyebrow when they were told to get up and jog around the classroom. Surprisingly, the second year Gryffindor didn't have any problem with that. He stood up and followed the rest of his classmates as they jogged around the class.

But then the tricky part came, answering questions while they were jogging? Kevin groaned but still listened to the question and his mind went blank after it was asked. Pressure, temperature and volume what? "SOMETHING!" He suddenly blurted out. He had no idea what the answer to the question was but everyone was shouting things and Kevin didn't want to be left out.
