BATS: Superheroes of the Night celebrates bats, the new Batman v. Superman movie, and superheroes in general in March. The Malayan Flying Foxes have arrived as part of the new features related to the exhibition. The largest species of bat in the world, weighing around 2 pounds, and boasting 5-6 foot wingspans, these giant fruit-eaters are not to be missed. Starting March 11, we offer science and Superhero fans to own a piece of Batman movie history when bat houses constructed from the set of Batman v. Superman: Dawn of Justice go up for auction on Ebay starting March 11. Superhero Sunday on March 20 offers the opportunity to dress as your favorite Superhero and see comics come alive as the Institute of Science celebrates all things superhero inside and outside the museum on from 1 to 4pm. We'll start by choosing sides and taking a selfie with Batman or Darth Vader to see who registers more Superhero selfie posts on Facebook and then help save the bats through special activities. Learn more about bat events.
