About this Product
A small, plain sphericon. It's a wee little thing, maybe the size of a marble, and it rolls in a straight line like one too, but not in a straight line (a sphere or cylinder can roll straight. A cone rolls around in tight circles. A sphericon wobbles, rolling in alternating half-circles as its cone faces take turns, and so follows a more or less straight path by wobbling back and forth)
