Hoberman Mini Sphere Expanding Universe Glow

The Hoberman Mini Sphere Expanding Universe Glow is the compact version of the classic isokinetic sphere designed by Chuck Hoberman. The mini scale expands and contracts in the same hypnotic motion as the original full-size sphere, with glow-in-the-dark plastic that charges under a lamp and lights up in low-light rooms.

• Mini-scale Hoberman expanding sphere with the original isokinetic motion
• Glow-in-the-dark plastic charges under light and glows in dark rooms
• Smooth open-and-close motion across the full range
• Compact size fits comfortably in smaller hands
• STEM-friendly demonstration of expanding 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 Glow Expanding Universe variant adds visual appeal that pairs naturally with bedtime use or low-light classroom demonstrations. The kinetic-toy category also continues to grow at retail, with parents and teachers picking up Hoberman spheres for STEM learning, fidget play, 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.
