COSI After Dark - a 21+ Event (August 7, 2014)

Geek out with grown-ups and fly a quadcopter inside COSI! Log some hands-on flight time with radio-controlled multirotor helicopters and be one of the first to try out COSI's quadcopter Aerial Battle Arena. Plus, explore classic COSI exhibitions, get lost in Adventure, check out special themed activities, and enjoy a cash bar. Plus, this is your last chance to investigate The International Exhibition of Sherlock Holmes at COSI without kids. Also enjoy live music: Columbus' Alt Pop band, Kid Runner at 8pm. Please note that sell-outs are possible. Walk-up COSI After Dark tickets will be available at the COSI Box Office for $16 ($10 for COSI Members). Timed admission tickets to The International Exhibition of Sherlock Holmes are $6 for COSI Members, $8 for nonmembers and can be purchased at the COSI Box Office on your arrival.
