Large Classic Hoberman Sphere

Description

Hoberman spheres are just plain cool. We like showing them to people that have never seen one before. When it's closed, they are unimpressed, but open it up and watch it triple in size and you have their attention. The Hoberman Sphere is the essence of transformation, expanding from 10" diameter to an incredible 32" with one easy motion. It's a combination of mathematics, mechanics, science, and structural engineering. This transforming sphere from Hoberman comes with a pulley, hardware, and instructions to hang as your own kinetic mobile. For ages 4+.
