This Weekend & Live Stream event from Wizarding World, the official fan site of the Harry Potter franchise, is hosting a weekend long online back-to-school event through Monday and a live stream event on YouTube and Facebook on Tuesday. Events include a departure of the Hogwarts Express at Kings Cross Station, trivia, and special guest appearances. Since school will be in session soon, the event will also offer online classes, like one that will teach fans how to cast spells from a wand choreographer. There will also be concerts featuring orchestras from all over the world playing music from the movies. Free to participate online at WizardingWorld.com
