RAINBOW HOBERMAN SPHERE   - This multicolored mini sphere will amaze kids and their friends. The Hoberman Sphere combines mathematics, geometry, and esthetics into a magical motion of surprising simplicity.
Inside the box is a collapsed sphere , a mere 5.5" in diameter.
But when it's pulled, it expands to 12" - more than double its original size!
It shrinks back when pushed, to make a perfect table- or desktop decoration.
Comes fully assembled, with a selection of game ideas.
