But she felt pleased with her effort. This was her first time trying anything like this, and she had at least slightly mastered it. She took a deep breath and raised her hand. "Professor, once we've turned our gecko into a goblet no matter how imperfect," she stated pointing to her particuarly imperfect water goblet, "do we have to wait for it to change itself back or do we need a spell for that?" She asked with a nervous smile.
