She smiled to herself, but it was hidden from the world by her hand which was rested on her chin. Unlike the others who seemed to be bored, Ophelia was indeed trying to think with the teacher. And as she was praised, hopefully she'd get some points for Ravenclaw at the end of the lesson for participating too, she did not dare to look around.
"Generally speaking we'd need some water, bottles into which we'd pour our potions into later and a brewing stand. And of course fire to heat the whole thing up."
Well, the professor had asked for the Basic things and Ophelia delivered the answer. Again, she did so quietly so only the teacher could have heard her.
"You add water to the cauldron, heat it up and add a primary ingredient. This has no effect whatsoever. By adding the second ingredient you will finally get something, but you also need to be careful of the instructions: as in you have to make sure you twist and turn the ingredients clockwise or counter-clockwise."
Those words, too, were mumbled more to herself than to anyone else besides the teacher, but who knew, maybe someone else wanted to say something.
