Calling all muggles, it's Harry Potter's 39th birthday! Join the Children's Museum in celebrating 'The Boy Who Lived' during the wizard-themed birthday bash. Guests will be able to participate in a youth Quidditch match, and receive acting lessons from TUTS acting classes. The activity-filled day will also feature a live magic show, lessons on how to use a wand, and a cake for Harry. The word is that even Harry, Hermione, and Ron will be making an appearance for pictures, celebration, and more.
