Center of Mass Trajectory

Odd-shaped objects with their centers of mass marked by orange paint are thrown. While the objects appear to follow very wobbly trajectories when viewed under bright lights, under black lights you can see that their centers of mass travel in smooth parabolas.

Then center of mass is not necessarily in the center of an object, as demonstrated by the last object in the video (a weighted disk).
