Starting Saturday, November 22, 2025, COSI will once again transform into a spectacular winter wonderland where science, imagination, and holiday traditions come together. From twinkling lights to immersive décor, Season of Celebrations is bigger and brighter than ever, inviting guests of all ages to discover festive fun around every corner of the science museum.
A Forest of Community & Creativity
This year, our beloved Forest of Community Trees moves to a new home in COSI’s Traveling Exhibitions Gallery on Level 2. Dozens of trees, decorated by local schools, nonprofits, and organizations, tell unique stories that highlight the rich diversity of the Columbus community. Stroll through this magical gallery and see how creativity and holiday spirit come alive in every branch.
New Holiday Zones & Décor
Season of Celebrations introduces exciting new themed zones throughout COSI, including:
- A life-sized yeti greeting guests in the Traveling Exhibitions Gallery.
- A cozy Winter Chill Speakeasy featuring seasonal food and themed drinks near the Community Forest
- NEW! Exhibit-inspired trees celebrating Pixar, Cracker Jacks, and Wild Kratts.
- Expanded photo opportunities, including dazzling displays at COSI’s main entrance and enhanced décor throughout our public spaces.
A Step Back in Time
The magic extends into COSI’s classic Progress exhibit, where visitors experience holidays as they were in 1898 and 1962. Thanks to a partnership with Columbus Children’s Theatre, actors will bring these streets to life with festive interactions from 12:00–3:00 pm, Wednesday–Sunday.
Science Meets the Season
In addition to the festive sights, COSI will host special science demonstrations, hands-on activities, and themed programming designed to connect the wonders of the season with the world of science and technology.
Join us this holiday season as COSI lights up with joy, imagination, and community during Season of Celebrations 2025!
