Hoberman Sphere Expanding Slowly

A Hoberman sphere is a collapsible, geometric toy that expands and contracts in a spherical shape. When expanded slowly, it demonstrates principles of engineering, geometry, and physics, showcasing how a complex structure can transform smoothly from a compact to an extended form. It’s often used as a visual tool to explain concepts like symmetry and transformation. This video is included in the phenomenon section of the Expanding Universe teaching guide.
