Exploratorium Community Free Days | 2020

The Exploratorium is a twenty-first-century learning laboratory, an eye-opening, always-changing, playful place to explore and tinker featuring hundreds of science, art, and human perception exhibits.

While they don’t have monthly community days, they do host certain special events throughout the year offering “pay-what-you-can” admission for all.

Please note, in past years, there were 4-6 free community days, but in 2020 there is only one. Enjoy free admission on Mother’s Day (May 10, 2020).

Please note in past years Pi Day was free admission. But in 2020 it looks like Pi Day is just a normal admission day.

To honor Pi Day, Exploratorium opens its door to offer free admission to all.

Welcome to the 33rd annual Pi Day, the mathematical holiday founded at the Exploratorium and celebrated by number lovers around the world. To honor the never-ending number 3.14159… (and Einstein’s birthday), participate in π-related activities, and enjoy a piece of pie.
