COSI After Dark: PRIDE PROM is your chance to relive—or finally experience—the prom of your dreams, just the way you want it. Kick off PRIDE Weekend with a night of dancing (yes, including delightfully awkward slow dances), dazzling drag performances, and hands-on fun. Hit the dance floor with our DJ and explore the art of natural dyes with Franklin Park Conservatory!
There are plenty of themed activities, plus you’ll enjoy the rest of COSI, ride the High Wire Unicycle, COSI Planetarium, and drinks at the cash bar from 7-10 pm. Buy tickets early!
Tickets for COSI After Dark tickets are $20 in advance, and $30 at the door. This event is for adults ages 21 and over, only. Valid photo ID required.

I’ve attended a few COSI after dark events and I must say that they’re an absolute blast to go to! Not only are you able to view all the exhibits with virtually no lines, but you have the added benefit of cash bars at almost every turn!
