From the website: Come play, build, and create in our very temporary 3,000-square-foot Cardboard Gallery. Assemble small forts for your toys or big forts for yourself! Create creatures, design mazes, and construct rocket ships in a gallery filled with cardboard to build and explore with. Hundreds of cardboard boxes will be available as well as an assortment of tools and connectors to help you turn your cardboard ideas into cardboard reality in this giant free build!

This event is free with the purchase of admission or membership.
