Utilizing a recently found class of exact, analytic rotating solutions of nonrelativistic fireball hydrodynamics, we calculate analytically the single-particle spectra, the elliptic flows, and two-particle Bose-Einstein correlation functions for rotating and expanding fireballs with spheroidal symmetry. We demonstrate that rotation generates final state momentum anisotropies even for a spatially symmetric, spherical initial geometry of the fireball. The mass dependence of the effective temperatures as well as the Hanbury Brown-Twiss (HBT) radius parameters and the elliptic flow are shown to be sensitive not only to radial flow effects but also to the magnitude of the initial angular momentum.
