Exact time-dependent solutions of c=1 string theory are described using thefree fermion formulation. One such class of solutions describes draining of theFermi sea and has a spacetime interpretation as closed string tachyoncondensation. A second class of solutions, corresponding to droplets of Fermiliquid orbiting in phase space, describes closed cosmologies which bouncethrough singularities.Comment: 21 pages, 6 figures, v2: added references, minor additions and correction
