The perfect texture for running you say? We couldn’t agree more. OMSI After Dark: Chill Out dives into cold weather science and how to relax during the slow, dark months of winter. Slip into your flannel pajamas and cozy up for a night of hot cocoa and snowflakes.

What to Expect: 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 are the curated vendors, lectures relating to the monthly theme, and the Planetarium will be hosting four shows. This month’s vendors and lectures will relate to winter science but there will not be an exhibit about it. Check out the list of vendors below to see who is coming!

Visit the Theory Restaurant during happy hour! Happy Hour is from 5-6pm for ticket holders in the Theory Restaurant. Grab a beverage or a bite to eat and once the doors to the event open at 6pm, you’re free to leave Theory and explore the event! This is for folks who pre-purchased a ticket for the event. Last entry to Happy Hour is 5:45pm.
