COSI brings hands-on science to a large building beside the Scioto River in downtown Columbus.
Exhibits explore scientific ideas through activities and environments that encourage visitors to test, compare, and investigate. The museum works especially well when a group can spend time on its preferred subjects rather than trying every activity in rapid succession.
Allow several hours and consult the current exhibition list before booking. Planetarium shows, films, and special exhibitions can have separate ticket or timing requirements, so build the day's route around the experiences you most want to see.
