Creatures of all kinds can be found at every depth of the ocean – from the surface to the seafloor. At Explorers Club: Sink or Swim, discover how animals move in the water using the principles of buoyancy. Explore buoyancy by meeting some animals, making a diver of your own, and mingling with a diver! For ages 11-14. Pre-registration required. Tickets are $60 for the Public, and $50 for Birch Aquarium Members. Annual memberships are also available. To purchase tickets or for more information, visit aquarium.ucsd.edu or call 858-534-7336.
