Summer’s in full swing and St. Louis is bursting with ways to stay cool, get weird, and have a damn good time. We’ve got vintage nightfests, tie-dye parties, sausage celebrations, pickleball showdowns, and 80s trivia battles. Oh, and the Science Center is throwing a disco. For grown-ups. About sound. (More on that below.)

Clear your schedule. Here’s what’s going down:

🎧 Up Late: Experience Sound!

Sat, July 19 • 6–10PM at the Saint Louis Science Center
An adults-only, after-hours takeover of the Science Center exploring the science of sound. Think silent disco, hands-on exhibits, themed cocktails, and “Two Scientists Walk into a Bar.”
🎟️ $15–$20 tickets

🛍️ Up Late Local Pop-Up Market

Sat, July 19 in Up Late (1904 S Vandeventer) (8 PM - ???)
A shop-local hangout with neighborhood vibes, artisan vendors, and outdoor charm.
