Rattleback Spinning Top

$2.50
A rattleback is a type of spinning top that prefers to spin in one direction due to its unique semi-ellipsoidal shape. When spun in the wrong direction, it will automatically shift the momentum until it spins in the opposite direction. This is caused by an asymmetrical mass distribution and instability between the rotational axes.

As the mass shifts, the rolling axis compensates in the other direction, which in turn causes the mass to shift more. This continues until the top is spinning in the preferred direction. But when spun in the “right” direction, the mass needs no compensation. 

Dimensions: 3 ⅞" x ¾" x ½"
