Extract from Harry Potter and the Philosopher's Stone
by J.K. Rowling
Professor Flitwick announced in Charms that he thought they were ready to start making objects fly, something they had all been dying to try since they'd seen him make Neville's toad zoom around the classroom. Professor Flitwick put the class into pairs to practise. Harry's partner was Seamus Finnigan (which was a relief, because Neville had been trying to catch his eye). Ron, however, was to be working with Hermione Granger. It was hard to tell whether Ron or Hermione was angrier about this. She hadn't spoken to either of them since the day Harry's broomstick had arrived.
"Now, don't forget that nice wrist movement we've been practising" squeaked Professor Flitwick, perched on top of his pile of books as usual. "Swish and flick, remember, swish and flick. And saying the magic words properly is very important, too - never forget Wizard Baruffio, who said "s" instead of "f" and found himself on the floor with a buffalo on his chest."
It was very difficult. Harry and Seamus swished and flicked, but the feather they were supposed to be sending skywards just lay on the desktop. Seamus got so impatient that he prodded it with his wand and set fire to it. Harry had to put it out with his hat.
Ron, at the next table, wasn't having much more luck.
"Wingardium Leviosa!" he shouted, waving his long arms like a windmill.
"You're saying it wrong," Harry heard Hermione snap. "It's Win-GAR-dium Levi-O-sa, make the "gar" nice and long."
"You do it, then, if you're so clever," Ron snarled.
Hermione rolled up the sleeves of her gown, flicked her wand and said, "Wingardium Leviosa!"
Their feather rose off the desk and hovered about four feet above their heads.
"Oh, well done!" cried Professor Flitwick, clapping. "Everyone see here, Miss Granger's done it!"
