Big fun, tiny package. The Mini Hoberman Sphere comes out of the box looking like a futuristic ornament — a cross between a ball and a star, and then boom — pick it up by any of its dozens of plastic points and it expands neatly into a lattice-like globe that's 12 inches in diameter. It's pocket-sized magic that fits in your bag, sits on your desk, and refuses to be put down. Perfect for kids, fidgeters, and anyone who just needs something satisfying to do with their hands.

The one that started it all. The Original Hoberman Sphere is the classic, award-winning geometric wonder that has been mesmerizing kids and adults alike for decades. Made of rainbow-colored plastic links, it expands to 30 inches in diameter and contracts back down to a compact 9.5 inches -- making it perfect for tossing, rolling, spinning, or hanging as a kinetic mobile.
