This classic copper Moscow Mule mug commemorates the spiral-shaped Pi shrine embedded in the concrete of our very own plaza, a pivotal element to our annual Pi Day celebrations. Ma rch around it 3.14 times every March 14th, sing happy birthday to Albert Einstein—again, it's tradition—and have a sweet, spicy, tangy drink with your pie. The Exploratorium's Pi Shrine 16oz mug is made from solid copper with a brass handle. Show more
