COSI Classics

Hair-raising experiences. Cherished childhood favorites. Demonstrations that seem magical. COSI Classics, like our live stage shows, hallway carts, and most of COSI’s iconic permanent exhibitions, are included with your general admission ticket or Membership. Drive a Mars rover in Space, see real-time research in Life, and lift a car in Big Science Park. Depending on COSI’s daily schedule, you may also find yourself holding a meteorite, rooting for your favorite rat to score another basket, or feeling the heat from an exploding hydrogen balloon. COSI is different every day, but wonder comes standard.

Explore at your own pace.

We all learn at our own speeds, and in our own unique ways. COSI’s spacious hallways and welcoming exhibitions invite you to explore the scientific world at your own pace. With more than 320,000-square-feet of floor space, plus ten major exhibition areas, there’s plenty to see, study, absorb, and do at COSI. Dive into the depths of the seas in Ocean. Time-travel in Progress. Experience the wonders of our Universe through a Giant Screen film. Where to go from here? It’s up to you.
