We have observed with high resolution the dense core around IRAS 3282, the exciting source of a highly collimated molecular outflow in the Perseus complex. Our ammonia data, a combination of VLA and 100 m Effelsberg observations, show the dense core has a cavity along which one of the outflow lobes runs. The walls of this cavity show evidence for acceleration by the outflow and present a shear-like velocity field that suggests the cavity has been evacuated by the fast gas moving in its interior. The IRAS source is not located at the center of the core, but displaced to one side, making the two outflow lobes travel through different amounts of dense gas. The one that has more material along its path seems to be composed of slower gas, another signature of the interaction between the outflow and the core. The collimation of the two lobes, however, is very similar, a fact that indicates the collimation is intrinsic to the outflow, and robust enough not to be affected by the dense environment.
