COSI After Dark is a monthly adults-only night (21+) that transforms the museum into a playground for grown-ups, with a fresh theme each time. Expect hands-on activities, games, and interactive experiences throughout the building, plus food, craft beer, and themed cocktails—all without a kid in sight. It’s a chance to explore COSI in a totally different light, with entertainment you won’t find on a regular visit.
