**Race Alert!**

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.


Ride a unicycle through the air...
2 stories up!

It’s all about balance. COSI’s High Wire Unicycle—the only one in the world—challenges you to ride a unicycle across an 84-foot cable while 17 feet above the ground. If your sense of balance isn’t world-class, don’t worry. The Unicycle’s 250-pound counterweight drops the cycle’s center of mass to well below your feet, keeping you safely upright at all times. Ready to ride?
Here's some tips for making the experience enjoyable!


A different experience
every time you visit!

The world changes, you and your family change, and so does COSI. With limited-engagement exhibitions from renowned science centers and museums, an ever-changing lineup of spectacular large-format films, and new science carts and demonstrations, you’ll learn something new about our fascinating planet every time you visit COSI. Planning to come back soon? Purchase a COSI Membership for an entire year’s worth of knowledge.

High Wire Unicycle Tips
You’ll need closed-toe shoes (sorry, no sandals, high heels, or Crocs), weigh under 250 pounds, and have at least a 25-inch inseam. If you’re pregnant, have heart conditions, back conditions, or motor skill disabilities, you’ll have to be happy watching other guests ride. To avoid disappointment, remember the High Wire Unicycle closes a half-hour before COSI does, and to accommodate guests fairly, the line may close earlier.
