After using Scourgify on his pestle and mortar, Adi quickly added the new instructions to his notes. Now to follow them. With the wooden spoon (which he had cast the Cleaning Charm on), he stirred seven times counterclockwise and then turned off the heat. He knew the tricky part was next and he seriously hoped that he won't have to start all over again. Glancing at his watch, Adi began his countdown to five minutes. But he need not worry for coming towards the five minutes, the vapor coming out of the cauldron lessened considerably. Yes! His potion was cool now and it was just a few seconds after the five minutes.

Moving on! "Scourgify!'' the second year said casting the charm on the metal spoon. He put the fire crab shell onto it and carefully and very gently he lowered it into the potion. No splash. Perfect. This was such a tricky potion to make! Right, now for the stirring. One time clockwise for about ten seconds...one stir counter clockwise for about ten seconds...and repeat until twelve stirs were completed. Done now, Adi removed the shell and set it on the tissues on his desk.
