Large Hoberman Sphere in detail
The story
The Hoberman sphere is a rigid structure that changes size without changing shape. Its inventor, Chuck Hoberman, applied the same principle to retractable arches and roofs.
What you'll see move
One turn of the crank and the sphere opens up to 30 cm across, its 24 arms spreading like a flower. Turn the other way: it folds back. At this scale, you can see every joint at work.
