The mini Hoberman sphere, patented by Chuck Hoberman, is an isokinetic structure that resembles a geodesic dome. Through scissor-like action of its numerous joints the sphere is capable of folding down to a fraction of its normal size. The largest existing Hoberman sphere is in the AHHAA Science Centre in Tartu, Estonia. Fully expanded, it is 5.9 metres (19 ft) in diameter.
