OAD: Sparkling Soirée

December 3, 2025 | 6-10 pm

For 21+ Only
The Museum

A 21+ year-end celebration at the museum

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

As we approach the longest night of the year, OMSI wants to throw a little sparkle and glow your way. Combination holiday party, new year’s party, and solstice gathering, Sparkling Soirée is a chance to dress up and celebrate the OMSI way, with science! And of course, sparkling wine, which you can sip with your own commemorative glass that comes with entry to the event.

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.
