Think this place is just for kids? Think again.
The Center of Science and Industry offers all-ages amusement with hands-on displays, elaborate traveling exhibits and amazing documentaries that play in the seven-story Extreme Screen Theater. The expansive museum just west of Downtown does what your junior-high math teacher never could: It makes learning fun and cool.
Those who can't come out to play during the day can check out COSI After Dark, a 21-and-older event that runs 6-9 p.m. every third Thursday of the month.
Runners-up: Columbus Museum of Art, Wexner Center for the Arts
