Intriguing, isn't it? Would anyone like to venture a guess as to
what is inside? That's a Boggart, that is. Very good, Mr Thomas. Now can anybody tell me what a Boggart looks
like? No one knows. When did she get here? Boggarts are shapeshifters, they take the
shape of whatever particular person fears the most. That's what makes them so - so terrifying,
yes. Luckily, a very simple charm exists to repel
a Boggart. Let's practice it now. Without wands, please. After me - Riddikulus! Riddikulus. Very good, a little louder and very clear,
listen - Riddikulus! Riddikulus! This class is ridiculous. Very good, well so much for the easy part. See the incantation alone is not enough. What really finishes a Boggart is laughter. You need to force it to assume a shape you
find truly amusing. Let me explain. Uh, Neville, will you join me, please? Come on, don't be shy. Come on, come on. Hello. Neville what frightens you most of all? Professor Snape. Yeah, he frightens all. And I believe you live with your grandmother? Yes, but I don't want that Boggart to turn
into her either. No, it's won't. I want you to picture her clothes - only her
clothes, very clearly in your mind. She carries a red handbag. We don't need to hear, as long as you see
it, we'll see it. Now when I open that wardrobe, here's what
I want you to do. Imagine Professor Snape in your grandmother's
clothes. Can you do that? Yes. Wand at the ready - one, two, three. Think, Neville, think. Riddikulus! Wonderful, Neville, wonderful, incredible! Okay, to the back Neville. Everyone form a line. Form a line. I want everyone to picture the thing they
fear the very most and turn it into something funny. Next, Ron! Concentrate... face your fear, be brave. Wand at the ready, Ron, wand at the ready. Riddikulus. Yes, very good, very good! Marvelous, absolutely very, very enjoyable. Parvati, next. Show us what you see. Riddikulus! And next. Step up, step up. Riddikulus! Alright, well, sorry about that. That's enough for today if you'd all like
to collect your books at the back of the class. That's the end of the lesson. Thank you. Sorry!
