The Hoberman Micro sphere, invented by Chuck Hoberman (the same man who invented the Switch Pitch) is an amazing expanding ball. Pull on opposite ends and it unfolds to almost twice it's original size. Or, for more fun, toss it in the air with a little spin and it will expand in the air. When you catch it, it shrinks back down again. You can also roll it on the floor and watch as it shrinks, or roll it down stairs to see it grow and shrink over and over. They come in two styles, Rainbow (which has like colors grouped together) and Color Jumble (which has each piece randomly colored). Small Diameter = 2 1/8 inches, Large Diameter = 4 inches.

Choose this option to get four Microspheres for the price of three. You can play toss with more than one, juggle them, or use them as stocking stuffers for your whole family or as a unique gift for your friends. They come in two styles, Rainbow (which has like colors grouped together) and Color Jumble (which has randomly colored pieces). You can choose whether you want two of each style, or four of one type. Small Diameter = 2 1/8 inches, Large Diameter = 4 inches.
