First Years, Lesson Five: Learning Flammeus Tailora (match into a needle)
Edward stood at the front of the classroom holding a large box of matches which he casually tossed from one hand to the other. "Good morning! How is everyone?" He asked by way of making conversation as the first years settled for the lesson. He got the attention of the student closest to him and motioned that he was going to throw them the matchbox "Ready?" He asked, then lightly tossed the box of matches for them to catch, "Oooh nice catch, have a house point. I'd like you to take a single match then pass the box along please. Nobody even think about lighting it unless you want to lose several house points and get absolutely drenched when I put out the flame." He told them with a wink, yet his voice was stern enough for his students to know he was being serious.
Once everyone had a match, Professor Pirrip summoned back the box and removed one match for the demonstration. "Today we are turning matches into needles and using the 'three tap' method again. The incantation for this is 'Flammeus Tailora'." He tapped his wand and cast "Flammeus Tailora" at the match. In the blink of an eye the wooden shaft became sleek metal, and the red phosphorus tip shifted into the needle eye for threading. "It is that simple. Well, as always, I will be walking around the room as you work. If you need something, raise your hand. And please turn your needles in for grading once you have finished. You may begin!"
Note: "Finite" is a counter-spell, not Untransfiguration, and shouldn't be used to reverse any transfigurations.
Homework: RP trying to turn your match into a needle! Extra credit to whoever claims the student catching the box of matches. Tag @Professor Edward Pirrip if you would like me to interact with your character!
