Pi Day and STEM Night Shirt, Mug and Gift Ideas

Pi Day comes on March 14, and STEM night tends to follow within a few weeks, which leaves the math teacher, the robotics coach or the PTA volunteer with a gym full of tables, a pie contest and a few hundred visitors to point in the right direction. Matching shirts make the student helpers easy to spot, and a good formula joke gets more laughs from that crowd than from almost any other.

Every item in our catalog has its own design below, from a pie with a lattice crust to a robotics hoodie, a circuit pun on a mug and a lab notebook cover, so you can see how a symbol, a mascot or an equation sits on each before choosing. Open any one in the designer and ask Remi to change it: your club name, your school colors, a different formula, or an idea that has nothing to do with pie. Youth and adult sizes share one order, and printing takes up to 10 business days, then shipping, so design it in February while the science fair boards are still blank.

Every design here is an illustration made with Remi, our AI designer, and every one can be changed: open it, then ask for your own names, colors or a new idea before anything is ordered.
