Hoberman Mini Sphere Rings Expanding Toy

The Hoberman Mini Sphere Rings delivers the classic isokinetic sphere motion in a compact size, with colorful ring segments that catch the eye as the sphere expands and contracts. The Mini Sphere keeps the original Hoberman design accessible to younger kids and travel-friendly for backpacks and toy bins.

• Mini-scale Hoberman expanding sphere with the original isokinetic motion
• Colorful ring segments rotate visibly as the sphere opens and closes
• Smooth open-and-close motion across the full range
• Compact size fits comfortably in smaller hands
• STEM-friendly demonstration of expandable geometric structures

Chuck Hoberman invented the original Hoberman Sphere as a demonstration of expandable geometric structures, and the design has anchored the kinetic-toy category for decades. The Mini Sphere variant gives kids a smaller, easier-to-handle version of the original at a more accessible price point. The Rings variant specifically swaps the standard solid color pattern for a more visually striking ring-segment design, which keeps the sphere interesting to look at even when not in motion. The kinetic-toy category also continues to grow at retail, with parents and teachers picking up Hoberman spheres for STEM learning and general curiosity-building. The sphere also makes a credible birthday or holiday gift for kids who lean into science-themed toys. The format also pairs well in classroom STEM kits.
