The World’s Largest Hoberman Sphere

The world’s largest Hoberman sphere hangs from the ceiling of the AHHAA Science Center in Tartu, Estonia, its form expanding and contracting in a hypnotic display of biomimicry.

In 1992, the American artist, engineer, and architect Chuck Hoberman designed the “Expanding Sphere” for the Liberty Science Center in New Jersey. The isokinetic structure, which is still on show in New Jersey (and remains the world’s second largest), resembles a geodesic dome, but one that can fold down to a fraction of its original size thanks to the scissor-like action of the joints within it.
