1veritasium's video shows a disc with a hole cut out of it on one side, spinning. The heavier side will prefer going to the top when spun. The reason this happens is due to the change in angular momentum. As angular momentum decreases, the disc will experience a torque orthogonal to L so that the angular momentum will change direction instead of decreasing. Because the center of mass is unbalanced in the disc, the heavier side will prefer the top as the disc can get much more torque per angle of declination in order to conserve its angular momentum.
