Telescoping Ball
★Exhibit Content: Hoberman sphere structure principle and universe expansion simulation ★Interaction: Electromechanical interaction ★Operation: Press the start button, observe the automatic expansion and contraction of the sphere, and experience the synchronized color changes of the lighting with the structure. ★Exhibit Description: The exhibit is a suspended Hoberman sphere device, consisting of a foldable mechanical grid sphere, suspension rods, drive mechanism, and gradient lighting system. It is a recommended exhibit from the PopsciCat Exhibit Store. The sphere uses a multi-node linked mechanical folding structure, suspended in the high space of the exhibition hall. When activated, the sphere uniformly expands and contracts under mechanical drive, simulating the dimensional changes of cosmic space expansion and contraction; meanwhile, the gradient lighting dynamically switches colors with the sphere's form, and the grid structure presents rich light and shadow layers under the lighting, allowing visitors to intuitively feel the charm of spatial scale changes in a dreamy visual experience, and concretely understand the astronomical concept of universe expansion. ★Scientific Principle: The Hoberman sphere is based on the principle of spatially deployable linkage mechanisms. Through multiple sets of hinged rods forming a spherical grid structure, the nodes are synchronously linked to achieve telescopic changes in sphere diameter, which is a typical application of deformable spatial structures. This structure is used to analogize the universe expansion model: cosmic space is like a spherical grid, uniformly expanding overall over time, with distances between galaxies increasing, and there is no absolute center of expansion. The exhibit transforms the abstract concept of cosmic space-time expansion into visible spatial morphological changes through dynamic changes in mechanical structure, helping visitors establish an intuitive understanding of cosmic space evolution.
