  • 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
