Description: Description: These crystallography ball toys display an endless arrangement of 2D hexagonal (and sometimes cubic) crystal grains as you tilt or shake them. They show holes and crystal defects as well as dislocations that form and move as you disturb them. They also show an unexpected behavior. A few seconds of vigorous shaking generates static electricity within the toy and causes the balls to weakly repel each other. The result is a fascinating flow of balls as they levitate and avoid each other while rolling downhill.
