It wouldnt be a ball if it was small enough. Youre fucking thick, dantes.
Really? What more must I do?
It would probably be a bucky-ball (https://en.wikipedia.org/wiki/Buckminsterfullerene), isolated from the environment by some arrangement of a Faraday cage and a vacuum, so as to ensure it's wavefunction remained coherent and protected from Einselection (https://en.wikipedia.org/wiki/Einselection).
