Hoberman Spheres — Great Office Stress Relievers!
Relieve stress and stimulate curiosity with a Hoberman Sphere. This colorful ball expands to create an interesting geometric sphere and easily folds back into its original shape. A great teaching tool and novelty item, a Hoberman Sphere is a unique addition to any workspace. Hoberman Spheres are isokinetic structures that typically consist of six great circles that correspond to the edges of an icosidodecahedron (a polyhedron with twenty pentagonal faces and twenty triangular faces). The Hoberman Sphere can fold down to a fraction of its normal size by the scissor-like folding of its joints. The largest Hoberman Sphere, housed at the AHHAA Science Center in Estonia, has a diameter of 19 feet when fully expanded! The largest Hobermen Spheres we have here at Office Playground are a tiny bit smaller, expanding to 32 inches in diameter. Chuck Hoberman calls himself an "accidental toy maker". He initially created his spheres to exist as installations at science museums. When he noticed how engaged kids were by his creations, he turned his sphere into a toy. Hoberman Spheres also have many other practical applications. The Precision Expendable Radar Calibration System (PERCS) is a satellite in development that is a giant Hoberman Sphere! In orbit it would expand from 1 meter to 10 meters. Bring these exceptional Spheres into your own orbit - they make fantastic stress relievers. A blend of mathematics, mechanics, and structural engineering, it's bound to fascinate you and the crowds of co-workers that will inevitably gather about to see it in action.
