Hold a Hoberman ball in your hand and you’ll be completely fascinated! These expanding spheres hold an allure for everyone from toddlers to grandparents and you can’t help but pull it out and push it back together like an accordian to see it expand and collapse over and over again!
The Hoberman ball is actually an icosidodecahedron made from six concentric circles and the complicated structure works thanks to the scissor joint at each intersection. It is sort of like how a folding chair works, except there are many more joints involved.
Chuck Hoberman is the inventor of the Hoberman sphere. Mr. Hoberman is famous for being an architect, artist and engineer as well as a toy inventor! What’s clear is that he has a very special kind of mind that was able to come up with a toy this complex, yet simple at the same time.
The largest Hoberman sphere in the world is in a museum in Estonia and measures a whopping 5.9 metres in diameter. Your Hoberman sphere, while not quite as large as that, will still be an impressive 76cm across.
Order a Hoberman sphere for the kids in your family! They are awesome “just because” gifts, party favour gifts or something to keep your child occupied during the summer holidays.
