Meanwhile, this event has no official connection to Pi Day, but maybe it's true that nothing happens by chance: The Book Stall partners with Bedtime Math, a New Jersey nonprofit aimed at getting kids to embrace arithmetic and beyond, for a math-based party. Kids ages 3-8 get to build geometric creations with glow sticks and foam balls before the lights go out. For more about the organization, visit bedtimemath.org.
