On the last Friday of every month, after 5pm, COSI offers extended hours and price reduced admission to families so you can visit, learn, and play late! General Admission is $15 per Adult, $10 per Youth, free for COSI Members, and includes all of COSI's permanent exhibitions. Watch and participate in learning about science in a fun way through hands on activities and demonstrations.
To enhance your COSI visit, buy tickets to our unforgettable add-on experiences, including stellar shows in the Planetarium, inspiring National Geographic Giant Screen Theater films, and a rip-roaring ride on the Motion Simulator. Add-on experiences will be available at the Box Office at check-in.
