  In this work we present an inflationary mechanism based on fluid dynamics.
Starting with the action for a single barotropic perfect fluid, we outline the
procedure to calculate the power spectrum and the bispectrum of the curvature
perturbation. It is shown that a perfect barotropic fluid naturally gives rise
to a non-attractor inflationary universe in which the curvature perturbation is
not frozen on super-horizon scales. We show that a scale-invariant power
spectrum can be obtained with the local non-Gaussianity parameter $f_{NL}=
5/2$.
