Hoberman Sphere Rainbow

The Original Hoberman Sphere Rainbow is an award-winning, expandable kinetic toy that combines geometry, engineering, and mesmerizing visual play. Constructed with patented scissor-like plastic joints, this colorful geodesic sphere magically expands from a compact 9.5-inch (24cm) ball into a giant 30-inch (76cm) structure with a simple push-pull motion.

Widely used as both a STEM learning tool and a mindfulness breathing aid, the Hoberman Sphere provides a clear visual model for geometric transformations, volume changes, and scissor-hinge mechanics. Therapists and educators frequently use its expanding and contracting motion to guide rhythmic deep-breathing exercises, helping children visually match their inhalation and exhalation to soothe anxiety and self-regulate emotions.

Crafted from durable, lightweight plastic in a rainbow of colors, the sphere includes a hanging pulley and hardware set, allowing it to be suspended from ceilings as a decorative, interactive mobile. Suitable for children aged 4 and up, the Original Hoberman Sphere offers endless tactile, visual, and educational value for homes, classrooms, and therapy spaces.
