Other activities for the evening include: viewing Penguins 3D in the Digital Adventure Theater: A National Geographic Experience; seeing stars and planets through the 10-inch refractor telescope in the Crosby Observatory (weather permitting); and conducting lab experiments in Dr. Dare’s Laboratory.
