20 years ago Harry Potter's first book was was released. To mark and celebrate the 20th anniversary of Harry Potter social media giant Facebook added a cute Easter egg for posts.
Mentioning the words “Harry Potter,” “Gryffindor,” “Ravenclaw,” “Hufflepuff,” or “Slytherin,” in a text post will cause the words to light up in their respective house colors (Harry and Gryffindor in red, Ravenclaw in blue, Hufflepuff in yellow, and Slytherin in green). As an added bonus: tapping on the Potter-related words causes a magic want to appear and shoot out sparks, just like in the books.
Here it is:
The number that Arthur Weasley enters in the phone booth to get to the Ministry of Magic with Harry is 6-2-4-4-2. The letters underneath those numbers on a standard telephone keypad spell out "magic."
When Voldemort died in the Battle of Hogwarts, he was 71 years old.
Professor Snape is based in large part on J.K. Rowling's old chemistry teacher.
