Abstract
The evolution of a plasmoid (fireball) ejected by localized microwaves from a solid substrate is presented. The plasmoid is first fed by the substrate material (glass in this case) through a plasma column, which is detached from the substrate, and then evolves as a stable fireball buoyant in the air atmosphere. The experimental characterization of these fireballs is presented, and their resemblance to the ball lightning in nature is indicated.
