It's the original Hoberman toy and it's now a classic and a favorite of kids and adults everywhere. It expands from 9" to 30" in diameter with a magical motion that amazes everyone that sees it. Everyone in the house should have their own, because nobody will want to share. 

All Spheres comes with a pulley, hardware and instructions to hang as a cool, kinetic mobile; an educational booklet about the geometry of the Sphere; and a 21 Cool Things to Do activity sheet. 

Ages 4 and up.
