Overview
Pi Day
Pi Day celebrates the wonders of circles, numbers, and discovery. On March 14, join us for hands-on fun where Pi isn’t just a number – it’s an experience. This family-friendly event is FREE for MOSI members or included in general admission for the day.
First, explore engaging activity stations located throughout the museum. Each station highlights patterns, measurement, and problem-solving. Next, take part in a collaborative Paint-by-Numbers mural that grows throughout the day. Meanwhile, live demos bring big ideas to life and keep the energy high.
In addition, enjoy special themed star tours in the Saunders Planetarium! These immersive shows connect math to space, innovation, and exploration. For an extra treat, specialty upgrades will be available at the door.
Hungry for more? Melt Machine will have melty sandwiches, wraps, and more for sale during the event!
While you’re here, grab a complimentary sample thanks to our sponsors—available while supplies last!
