smash 10-20 pounds of neodymium magnets with a hammer until it is nothing but shrapnel and shards. Clump them together and the magically form a spherical shape.

>no it's a toroid

Yes.
Well then take that clump and mount it on a drill and spin it till the centrifugal force makes it form a sphere. Then it will start to fly apart because it no longer has the CAPACITY TO STORE ROTATIONAL ENERGY.
This is why bubbles form spheres and become unstable and may pop when distorted. The sphere is natures most efficient way of storing the most energy but at heart it is really a toroid that is "full". This is why you see spherical shapes in nature.
And there is really no more proof to be shown, everything is purely observational so go observe some spheres.
