Across campus, students are donning their capes and polishing their broomsticks—not for Halloween—but for the opening of the much-anticipated seventh and final installment of the Harry Potter movie series. “Harry Potter and the Deathly Hallows: Part 1” debuts on Nov. 19 in theaters. For those itching to dress as Harry or Hermione long before then, the Harvard Museum of Natural History (HMNH) will be hosting Potter-themed festivities over the next few weeks.

On Oct. 30 from 2 p.m. to 5 p.m., students are invited to come to HMNH dressed as their favorite Harry Potter character and essentially experience Hogwarts in real life. Different stations are placed throughout this magical school of witchcraft and wizardry: Magical Creatures, Wizardly Wands, Life’s Secrets, and Potter’s Potions, where participants can even make their own concoctions.

From Oct. 30 through Nov. 28, the museum will also offer a Harry Potter Scavenger Hunt, featuring specimens “from wolves to wolfsbane and snakes to snowy owls,” according to an HMNH poster.

Best of all, the events are both free for Harvard students—the only thing we love more than wearing costumes.
