Cale walked in and sighed at the number of people he saw waiting in line to complete their assignment. After he had waited for what felt like an eternity, he grabbed an empty cup and prepared a label for himself

Then, placing it on the desk gently, he pointed his wand to it and muttered "Aguamenti" and watched as the cup started filling with water. There...easy as pie. He repeated the spell another two times before the cup was completely full, and he left it on the desk with the rest of them. "Here ya go Professor," he said with a grin as he placed it carefully between Anna and Allie's cups.
