Pizza and Pajamas

Step into an exclusive evening event designed just for you and your smallest scientists! COSI’s Pizza and Pajamas invites you and your little learner to “learn through play” in highlighted COSI exhibitions with children their own age. Plus, you’ll get hands-on with can’t-miss experiences developed just for scientists ages 2 through 6. And it wouldn’t be a “Pizza and Pajamas” party without pizza for dinner and a dance party to end the night! Laugh, learn, and play together in your pajamas!
