  We present a simple model of a multi-quark droplet evolution based on the
hydrodynamical description. This model includes collective expansion of the
droplet, effects of the vacuum pressure and surface tension. The hadron
emission from the droplet is described following Weisskopf's statistical model.
We have considered evolution of baryon-free droplets which have different
initial temperatures and expansion rates. As a typical trend we observe an
oscillating behavior of the droplet radius superimposed with a gradual
shrinkage due to the hadron emission. The characteristic life time of droplets
with radii 1.5-2 fm are about 9-16 fm/c.
