The wizard world of Harry Potter will be descending on the Ontario Science Centre in Toronto Thursday.

James and Oliver Phelps, who play Fred and George Weasley in the Potter films, kicked off the opening of the exhibition.

Fans can interact with and see first-hand the costumes, props and sets used in the films.

"The science centre seeks out temporary exhibitions that will appeal to our traditional audience and attract new visitors who may never have visited a science centre," said Lesley Lewis, CEO of the centre.

Areas of the exhibit feature vignettes inspired by the film sets, such as the great hall, Hagrid’s hut, and the Gryffindor common room.

Fans will also be able to immerse themselves in activities such as Quidditch and pulling a screaming mandrake from its pot.

The exhibition will run from April 9 to August 22.
