Today he figured that he would be giving a lecture to help the older students transfer over to the more advanced spell work. Being the last lesson of the year, he figured that the best use of their time was to create a conversation, talk about poisons and its importance and it's use in the wizarding world. Writing on the board Detecting Poisons he sat down on his desk, waiting for his students to arrive. He already had a feeling that some of them would not take kindly to actually talking and not making a potion, but he wanted to hear their opinions on the subject, show more than just potion work, but their minds and creativity.
Thus the class lacked any cauldrons, the tables clean, shining brightly with no hint of any phials had touched the surface. Today was an experimental idea, seeing if he would want to continue these kinds of lessons.
