Mini Hoberman Sphere - Rings
Serious Item Code: 4251
Like the large Hoberman Sphere, this portable version dramatically expands. Pull on the hubs and watch it open from 5-1/2" to 12" —increasing 10 times in volume! Push on any hub, tap it or roll it and it magically closes again. This specific Hoberman sphere has a ring design.
Plenty of fun, the Hoberman Sphere might get kids thinking about mechanical engineering and some folding/unfolding projects of their own.
