Warner Bros. has developed a Parseltongue translator – put in a message and it will be converted into Parseltongue! For non-Potter fans, Parseltongue is the snake language that both Harry and his nemesis, Voldemort, speak. (they’re known as Parselmouths).
Once you’ve typed in a message and it has been translated, you can choose to email the message, post it to Facebook or Twitter or download an mp3 version. Be warned though – Parseltongue is a pretty creepy sounding language!
