The Center for Science and Industry (COSI) in downtown Columbus has been a great place to visit for close to four decades! Enjoy three tickets to COSI, which features more than 300 interactive exhibits throughout several discovery-based and themed exhibition areas -- Gadgets, Life, Little Kidspace, Ocean, Space, Progress and outdoor Big Science Park -- an Extreme Screen Theater, a restaurant, and a retail shop. The exhibition areas provide experiences for all age levels to creatively combine science facts and learning through play.
