Flagstaff Festival of Science: Busy Builders

Put on your hard hats because it’s time to stack, stick, and build together!

Explore the world of building with big blocks, foamy friends, and tasty graham cracker castles. Hands-on, imagination-packed fun – designed for little learners (ages 3-4).

Part of Flagstaff Festival of Science, a free annual 10-day event wholly designed to promote awareness and enthusiasm for science in and about northern Arizona and beyond, and is fondly known as the Best 10 Days of the Year. Established in 1990, it is the longest, continuously running, entirely free science festival in the world.
