Admission Resize text Who doesn’t love monsters and things that go bump in the night? Campers explore all things spooky at the Smithsonian. Is the Smithsonian Castle haunted? Can you spot real monsters at the National Zoo? Can a field trip help us learn the secrets of mad scientists? Campers visit the museums, explore entomology, chemistry, electricity, and learn the history of some real "spooky science." They throw a Friday "Mad Monster Party" to celebrate what they’ve learned.
