Giant Aquarium

Start with the tank: a twenty foot ring of cardboard with a blue-tinted plastic ceiling.  Paint the inside like an undersea landscape.  Create puppets of fish, squids, whales, sharks and urchins to populate the aquarium.  Make diving gear to explore. Last, but not least, attach an observation room with windows to look in the tank; we’ll take tickets from friends and parents to visit and watch the action.
