In honor of Harry Potter’s birthday, the Stabler-Leadbeater Apothecary Museum is offering family-friendly tours that explore the Muggle science and medicine behind J.K. Rowling’s “Harry Potter” series. Event partner Hooray for Books! will be selling wizarding merchandise on site, and Dolci Gelati will have Butterbeer gelato available in their shop. Activities include potion-making and a photo booth—don’t forget your camera. Tickets are available starting July 1, and advance purchase is recommended, as this event sells out. Children must be accompanied by a ticketed adult.
