Hoberman Expanding Sphere

This amazing sphere expands from 9.5

The Hoberman Sphere starts small and grows larger. And vice versa. Made of rainbow-colored plastic links, the sphere expands to 30 inches in diameter and contracts to a compact 9.5 inches. There's a hypnotic fascination in making the sphere expand and contract over and over again, but if kids want to do more with their sphere, a guide (included) lists some possibilities. How about trying the ballerina spin, the flip down, or the hot potato? The sphere can also be a fashion accessory. Think spiked hat or, even better, space helmet. Another option is to hang the sphere as a mobile. A pulley system is included, and a pull of the ring will cause the sphere to contract. Release the ring for expansion. Plenty of fun, the Hoberman Sphere might get kids thinking about mechanical engineering and some folding/unfolding projects of their own. Winner of the Parents' Choice Award. It makes for an interesting game of catch! It's fun to ponder the mathematics and beauty of this expanding sphere.

The Hoberman Sphere is a fascinating and visually captivating toy that engages both children and adults alike. Composed of rainbow-colored plastic links, this geodesic dome-like structure expands and contracts in a mesmerizing display of engineering and art. The seemingly simple act of pulling or pushing on the sphere results in a complex, fluid motion that feels almost magical. Kids can't help but be enthralled as they transform the sphere from a small, compact shape into a much larger, intricate structure. The eye-catching colors further enhance the experience, adding an extra layer of excitement. Beyond its entertainment value, the Hoberman Sphere also provides educational benefits by sparking curiosity about geometry, mechanics, and spatial reasoning. It's a toy that invites exploration, hands-on interaction, and wonder, making it a gateway to understanding more complex scientific principles.
