Abstract
An Euler disc comprises a metal disc body having a maximum radius, an upper surface, a lower surface, a circular polished rounded edge joining the upper surface and the lower surface, and a maximum thickness. The upper surface is formed so that the cross-sectional area of the disc body that is above a horizontal bisector line and outside of a vertical quarter line drawn at one half of the maximum radius is less than 75% of the cross-sectional area of the disc body that is below the horizontal bisector line and outside of the vertical quarter line.
