March 14 isn't just any ordinary day—it's π Pi Day and also marks the birthday of the legendary Albert Einstein! Nearly two decades ago, the Children’s Museum Houston sparked the original international sensation surrounding π Pi Day, and the excitement hasn't stopped since! Join us as we celebrate the infinite, non-repeating number 3.14... by shutting down our street for an epic showdown in a wild, Pi Day-induced frenzy during our 20th Annual Pi Day. The chaos kicks off at 1:59 p.m. (because the numbers follow 3.14159), plunging you headfirst into the heart of the π Pi-Day celebration. Get ready for a day packed with all things π Pi, guaranteed to be filled with laughter, learning, and endless fun!
