This is not your ordinary sphere, nor your typical toy. This incredible and space-shifting sphere expands and contracts with a magical motion using a combination of geometry, engineering and beauty. By lightly grabbing two ends of the sphere and pulling, you can make it expand from 5.5 inchesin diameter to a whopping 12 inches across in the blink of an eye! Contract two of the lines ranging from the center meeting opposite points on the perimeter of the sphere and you can implode the sphere again and collpase its structure inside itself again! You can also cause the contracted sphere to expand by tossing it into the air. Catch it on your fist and close it around your hand. These amazing toys are tools for teaching and objects of art that are both educational and fun. Hoberman uses technology and unique designs to inspire children to be creative and inventive.
This particular sphere glows in the dark, allowing you to play in the dark and intiutively explore geometry at all hours. Incudes a game and activity sheet to help you explore all kinds of interesting ways to use it!
