Bodies of water are frequent metaphors in poetry, due to their unfathomable depths, unknowable sprawl, and unattainable porpoises. Plumb the enigma of the ocean with today's Groupon: for $13, you get two adult admission tickets to the Shaw Ocean Discovery Centre, located in Sidney (a $26.88 value). The Shaw Ocean Discovery Centre is dedicated to exposing aquanauts of all ages to the marvels of the sea. The Gallery of the Salish Sea re-creates local habitats, structured with air bubbles so visitors can enjoy a panorama of the wolf eels, rock fish, and octopuses that populate the coast. Touch pools provide the opportunity to shake hands with a sea star, tickle an urchin, or arm-wrestle a Kraken, and the Ocean's Heartbeat exhibit allows visitors an up-close look at the tiniest denizens of the deep through the lens of a microscope.
