Today is the official 20th anniversary of the Harry Potter franchise. The first book, Harry Potter and the Philosopher’s Stone (later retitled “the Sorcerer’s Stone” in America), was released 20 years ago, on June 26th, 1997. To celebrate, Facebook has added a cute Easter egg for posts on the social media service, as spotted by The Next Web.
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.
