Whoa.

Remind her to never get on Professor Noble's bad side. She watched as points were docked and masks were banished to the table by the door. Maddie glanced down and tried not to meet anybody's gaze. It was one of those awkward moments in class when the professor is suddenly in a terrible, points-taking mood, and she didn't want to get involved in any way whatsoever.

Ahem.

...and now they had to collect urine?! What was with Herbology and Potions class today? Between the stench and the collection of urine, she'd secretly be glad when they wrapped all this up. Without a word, she collected the urine, a medium clove of garlic, and a glug of castor oil. Thanks, Emmalyn, for clueing her in as to what a glug even was. After making sure her cauldron was good and clean and nothing had trickled its way inside, the third year added the castor oil to her cauldron.

As the lesson continued, Maddie picked up her cauldron and swirled the oil up the sides a few times. When it was back on the tripod, she turned the burner to low then measured out five tablespoons of beetle eyes. When that was done, she collected five whole beetles, put them in her mortar, and then began to grind them with her pestle.
