The cobwebs are getting dusty. The black cats are roaming at night. The lights flicker on and off. That can only mean one thing…OMSI After Dark: Spirits is back. Dust off your favorite costume and spend an evening learning about the spooky science related to Halloween. 

OMSI After Dark is a monthly event for guests 21 and over to explore the museum with a beverage in hand. On top of being able to roam the museum without minors, the added bonus of these events is the curated vendors and lectures relating to the monthly theme. The Planetarium will host four shows, and the Featured Exhibit is open for an additional fee. This month’s vendors and lectures will focus on farming, but there will not be an exhibit on it. Check out the list of vendors below to see who is coming! 

Note: Weapons are not allowed. If masks are part of your costume, they must be removable. 

21+ Only | A valid government-issued ID is required for entry for all attendees
