Christy got up and retrieved a plant with some healthy looking. She took the plant back to her desk and walked to the back of the room. She got a pair of tweezers and a rock from one of the shelves, she returned to her seat and picked one of the leaves carefully, leaving it on the top of the rock. Then, Christy placed her wand above the rock and with a spell, she started heating up the rock. She made sure the temperature was warm and not too hot or too cold to avoid burning the leaf.
