COSI Columbus Review
More than 18 million people have come through COSI's doors since it opened in 1964. Interactive exhibits at this first-class science center allow you to explore underwater shipwrecks, discover hidden treasures, or join an archaeological dig. Find the country's only high-wire unicycle at the outdoor Big Science Park. You'll also be able to time travel in "Progress," leaping from 1889 to 1962 in the blink of an eye.
