We're still living the dream.
The official Harry Potter Book Night: A Night of Spells event kit is marvellous. Pity it's on the first week of new school year. I know a class (or two) that would love it.
A PERFECT PATRONUS
In Harry Potter and the Prisoner of Azkaban, Harry learns how to cast a Patronus Charm.
How to cast one:
‘With an incantation, which will work only if you are concentrating, with all your might, on a single, very happy memory.’ Professor Lupin
Incantation: Expecto patronum!
Each person’s Patronus Charm takes the form of a different animal. Harry’s Patronus is a stag, whereas Hermione’s is an otter.
