Sky cast "Scourgify!" on her gloves, mortar and pestle. She was not taking anymore chances. She slipped her gloves on, walked over to the Dransul plant, and plucked three of the leaves. She walked back to her cauldron and placed one of the leaves in her pestle. She crushed it until the acid inside was oozing out. Then she grabbed her dropper, "Scourgify!"-ed it, and used it to add the three drops of the acid. Sky then picked up her stirrer, "Scourgify!"-ed it, and used it to stir the potion three times counter clockwise.
