It's all led by the friendly Master of Wizarding, Hogwarts, who's teaching his trainees some tricks of the trade.
There are wizards having their heads cut off, wand-waving and levitating silver balls.
And they even use the Wingardium Leviosa spell, made famous by Hermione in the Potter books, to make things fly.
Order of the Phoenix
OK, so what's really going on?
Waterstone's the book shops are training up loads of actors to play wizards, to keep you amused as you queue up for your copy of Potter book five.
They'll be on hand to show off their tricks and magic while fans wait to get their hands on the Order of the Phoenix.
'Potter gets better and better'
The Master of Wizarding, Hogwarts, told us: "We want to make sure everyone has a great time. Potter fans will realise that magic really, really is real.
"I love the Harry Potter books, I can't put them down."
Head boy at the Wizarding School, magician Boo Hiccup, agreed. "I can't wait for book five to come out, I've been waiting sooo long. They just get better and better."
'Party'
A bookshop spokesman added: "This is going to be huge. The book is over 700 pages long and weighs nearly a kilogram.
"It'll be a real party atmosphere. We can't wait."
