[gtazzqyp] Fun with moment of inertia

Create a collection of spheres all with the same size and mass, but very different rotational moments of inertia.  Internal mass distribution is always spherically symmetric, but some have the mass concentrated at the center, some in a shell near the surface.

People can hold, roll, maybe throw them, noticing which are easier or harder to impart spin.
