The evolution of spherically symmetric unstable scalar field configurations (``bubbles'') is examined for both symmetric (SDWP) and asymmetric (ADWP) double-well potentials. Bubbles with initial static energies E0\la E\rm crit, where E\rm crit is some critical value, shrink in a time scale determined by their linear dimension, or ``radius''. Bubbles with E0\ga E\rm crit evolve into time-dependent, localized configurations which are \it very long-lived compared to characteristic time-scales in the models examined. The stability of these configurations is investigated and possible applications are briefly discussed.tic time-scales in the models examined.
