An annual 21+ Halloween bash
21+ Only | A valid government-issued ID is required for entry for all attendees
Don your finest gourd for the biggest party of the year, where folks come from far and wide (the east and west side) to get a little weird at the local science museum. This year we’re making a pivot away from a focus on liquor, moving the spirits from the glass to the stage with more science and entertainment than before.
OMSI After Dark is for guests 21 and over, where you can have a drink and wander the exhibits after hours. We offer science demos, performances, DJ’s, artisan food and beverage vendors to sample their products, community vendors, local educators, and more to help enhance your museum experience. Each event has a different theme, which allows us to shake things up a little each month.
