Calling all the brainiacs: A totally “irrational celebration of the brain” is taking over Philly’s premier science museum, The Franklin Institute. Test the limits of the old noggin and show off your smarts with hands-on science activities, engaging demonstrations and expert-led dissections in honor of Pi Day and Brain Awareness Day.
Journey around the universe in an interactive show, Pi in the Sky Tonight; be one of the first 314 braniacs to find the Pi Day cart and win a limited-edition Spiced Apple Pie donut from Federal Donuts; or get up-close-and-personal with the brains of humans, snakes, dolphins and more.
Where: The Franklin Institute, 222 N. 20th Street, Philadelphia, PA
