In 2021 Cas collaborated with Liberty Science Center to design Wobbly World, an immersive exhibition for kids 5 and under that explores balance, motion, and cause and effect in a colorful landscape of moving, spinning parts and stackable pieces.

Designed around the concept of balance, the 2,600-square-foot exhibition draws inspiration from art, physics, and an intrepid toddler's first steps. From the time babies first try to balance their big heads and sit up (and fall over), to toddlers taking their first steps, to preschoolers scaling playground equipment — children are constantly practicing and strengthening their balance skills.

At the center of the gallery is the iconic giant Body Mobile: part carousel, part Calder-style mobile, all powered by play. As young guests hop on colorful seats and surfaces that dangle from the 14-foot-tall center column, they swing, spin, and teeter-totter bringing the giant structure to life. On one side of the gallery, kids explore Balancescape, a fanciful landscape of hills and ledges, testing their balance and agility as they find their footing. Along the opposite wall, young learners can build and explore with a whimsical collection of oversized Balance Blocks. The blocks also form a giant puzzle: each unique block shape fits into a matching slot in the wall.

In addition to the grand-scale kinetic experiences, Wobbly World engages young learners in smaller, hands-on explorations of balance. At the Mobile Building Station, tiny hands can create a tabletop mobile by hanging mini versions of shapes seen around the gallery on a permanent mobile base at the center of a table. At the Scales and Stacking Station, there are tactile wooden shapes to grab, sort, stack, and balance on scales.

Cas's hope for the exhibition is that it becomes a space where children feel comfortable exploring things they aren’t familiar with. Comfort in uncertainty is now more critical than ever, and when children get to exercise this skill early on, it has a lasting impact on how comfortable they are figuring things out as adults.
