Product Descriptions

It ís huge, really huge. It opens to over four feet in diameter (that ís taller than your average first-grader!). Six latches safely lock it in the open position to create the perfect playhouse for indoors or outdoors. Roll it around, climb inside' it ís great for the yard, the beach or a birthday party. When the party ís over, it collapses small for easy storage. Activity and Game Sheet included. Ages 6 and up. The Hoberman Sphere combines mathematics, geometry and aesthetics into a magical motion of surprising simplicity, beauty and fun. This polyhedral toy is similar in design to a geodesic dome. A game and activity sheet is included. Everyone who sees these spheres is fascinated. You can use this for physics or astronomy to demonstrate the idea of an expanding universe, for mathematics to show the volume, surface area and diameter relationships of a sphere or for chemistry to model Charles and Gay Lussac's Gas Laws as applied to a soap bubble. Great for a party. Its system of polymer links expands and contracts almost effortlessly, changing in volume 30 times. Hang it from the ceiling and using the pulley, create an expanding mobile you can open and close. No assembly required. Hoberman Associates' work is centered on the fundamental idea that a designed object can transform the way a natural organism does. While the smooth transformation of size and shape is ubiquitous in the natural world, it is rare among man-made objects. Hoberman has extensive experience in building structures that change their form, an ability that can be used for many different functional applications. Instant spaces can be erected for temporary use. Walls and roofs can retract to transform a space from indoors to outdoors. Structures can transform to create exciting venues for performances and entertainment.Ages 6 and up
