Coulomb's Explosion can indeed occur at the macroscopic level, particularly with large, visible bodies such as conducting spheres. When the electric field at the surface of a negatively-charged conducting sphere exceeds the work function, electric-field emission is initiated, similar to the field emission observed in RF cavities. Conversely, a positively-charged sphere does not emit electrons but can eject chunks of positively charged material. This phenomenon highlights the significant effects of electrostatic forces on larger scales.
