Harry Potter: the famous hero who switched from books to displays of cinema. The Harry Potter series turned twenty years old and to celebrate it Facebook adds magic to posts containing "Harry Potter", "Gryffindor", "Ravenclaw", "Hufflepuff" or "Slytherin".
Try typing a name into your phone's Facebook app and a moving magic wand will appear that casts a spell when hit.
The above news is about those who have nothing better to do naturally.
Both Harry Potter and the Gryffindor appear in red, while Slytherin, Ravenclaw and Hufflepuff are in green.
Unfortunately, the easter egg does not include other remarkable characters from the Harry Potter series, such as Albus Dumbledore, Rubeus Hagrid, Hermione Granger and Ron Weasley.
