OverviewHigh Quality Content by WIKIPEDIA articles! A Hoberman sphere is a structure that resembles a geodesic dome, but is capable of folding down to a fraction of its normal size by the scissor-like action of its joints. Colorful plastic versions have become popular as a child's toy: several toy sizes exist, with the original design capable of expanding from 15 cm (6 inches) in diameter to 76 cm (30 inches). A Hoberman sphere is not a true sphere, but a polyhedron known as an icosidodecahedron. The Hoberman sphere can be unfolded by allowing certain members to spread apart. This can be accomplished by feeding out a string or cable in the larger models. The operation of each joint is linked to all the others in a manner conceptually similar to the extension arm on a wall-mounted shaving mirror. Full Product DetailsAuthor: Lambert M.
