Janelle took notes as the Professor spoke. She was careful to write down the details of the potion that they would be brewing. Once she was finished writing, Janelle set to work. First she gathered her equipment and began to clean it. She saved her cauldron for last and waved her wand, sending a big "Scourgify" in its direction.

Now it was time to practice the spell. Janelle started with the incantation, as usual. She was careful to say it slowly and precisely at first. "Ap-toh-press-soo-rah, Ap-toh press-soo-rah, Apto pressura." When Janelle was comfortable with the words, she went on to practice the wand movement.

Lifting her wand, Janelle made a vertical line making sure to keep it straight from top to bottom. She repeated the movement several times and then she felt ready to try it for real. First though, she had to start her potion. Janelle took her wand and held it over her cauldron. "Aguamenti", she said as the water flowed from the tip of her wand into the cauldron. When it was half way full, she said, "Finite". Then Janelle took a deep breath. She made another vertical line with her wand and this time said, "Apto pressura" simultaneously.

Janelle hoped tha she had done the spell correctly. She guessed that she would know soon enough. Reaching down, she temperature at 100 degrees celcius and waited. She had to get this spell right.
