OMSI After Dark: Bogs and Swamps is the April Earth Day theme, with a marshy twist. Vendors and lectures will revolve around the world’s bogs, swamps, marshes, and wetlands — so come embrace Rot Girl Spring.

Unfamiliar with the event? OMSI After Dark is for guests 21 and over, where you can have a drink and wander the exhibits after hours. Interact with hands-on science experiments, live performances, local educational groups, lectures, food and beverage samplers, and more. Each event has a different theme, which means a new set of people and entertainment to engage with each month!
