The two minutes were up. Samantha fetched a small metal bowl and cleaned it by aiming her wand inside and saying,
"Scourgify." She used the same spell on her tongs and gloves. Samantha then headed for the teacher's desk and using her tongs grabbed ten ice cubes and placed them into her bowl. She walked back to her cauldron and tipped the ice cubes carefully into her cauldron. She then cleaned the tongs and bowl using,
"Scourgify."
Whilst she was waiting for the ice to melt, Sam grabbed her grater and aimed her wand at it and performed the cleaning spell. She grabbed five carrots and began to grate them carefully so that there were no accidents. After she grated the carrots, Sam added the five whole carrots into the cauldron and then she sprinkled the grated carrot over the potion's surface. She then pointed her wand at her grater and said, "
Scourgify."
Soon (five minutes) the ice had melted and it was time for the next step. Sam cleaned her gloves and tied the wormwood carefully around the knotgrass and dropped the bundle carefully into the cauldron.
