product description

Weighted Rattleback: prefers to spin counter clockwise. If spun clockwise, a complicated combination of friction, precession, and instability induced vibrations transforms the rotational energy into into rattling (energy of oscillations) and then into rotational energy in the opposite direction! For this rattleback design, this behavior is related to the asymmetric placement of weights near the ends which are slightly rotated off of the line of symmetry.
