We investigate the existence of stable charged metallic bubbles
using the shell correction method. We find that for a given
mesoscopic system of n atoms of a given metal and 
(positive) elementary charges, a metallic bubble turns out to
have a lower total energy than a compact spherical cluster,
whenever the charge number q is larger than a critical charge
number qc.
For a magic number (
) of free electrons, the spherical
metallic bubble may become stable against fission.
