COSI - Center of Science & Industry

Steve’s take

COSI is about 45 minutes east of I-75 via Columbus, so this is only for families taking the I-71 connector or making a deliberate detour. But if your kids are the 'touch everything' type, this is the best science museum between Detroit and Atlanta. The outdoor adventure park, the planetarium, the giant spinning chairs — you'll get three hours of silence in the car afterward because they'll be asleep. Worth the detour for the right family.
