Penn State hosted their annual Halloween Science Event “Haunted-U” that spanned out events all over campus. The ASA student chapter hosted a classroom that included a spooky “Stranger Things” decoration theme with fun acoustic demonstrations like the Ghost String (vibrating string with a strobe light), Possessed Plate, and Monster Modulator where children’s voices were filtered to sound like a ghost, demon, robot, and more. The night was a hit, and we are already excited to volunteer again next year!
