This year's opening reception will be unlike any other. COSI is designed to enlighten, entertain, and amaze you. Attendees will experience science, technology and innovation at work through more than 300 interactive exhibitions and more than 100,000 square feet of exhibit space, including the country's only high-wire unicycle. One of the newest exhibits is the Labs in Life, a state-of-the-art laboratory where researchers from The Ohio State University conduct studies on physical activity, nutrition, and body composition using cutting-edge equipment.
