Original Expanding Universe Hoberman Sphere Transforming 9.5 to 30 Inches Glows!
The Hoberman Sphere combines mathematics, geometry and aesthetics into a magical motion of surprising simplicity, beauty and fun. This glow in the dark sphere magically transforms from 9.5 inches to 30 inches. Toss it around the dark and watch the glowing fireflies dance, or suspend it from your ceiling and let the fireflies send you off to sleep! 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 - you will not want to put it down. Ages 4 and up.

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. Windbreaks and sunshades can respond to changes in weather or time of day. Expands from 9.5 tp 30in.
