Compact Hoberman Sphere in detail
The story
In the late 1980s the American engineer and artist Chuck Hoberman invented structures able to unfold and fold back while keeping their shape. His sphere, which became a famous toy in the 1990s, relies on scissor mechanisms, and the same principle has produced retractable arches and roofs.
What you'll see move
Turn the crank: the sphere grows as all its articulated arms spread out together. Turn the other way: it closes up again. In its compact format, the model fits on a corner of your desk.
