In particular, even without external pressure a self-bound liquid puddle of constant density will form. We investigate the symmetric case of two identical layers, corresponding to a two-component Bose system with equal partial densities. The zero-temperature equation of state $E(\\rho)/N$, where $\\rho$ is the total density, has a minimum, with an equilibrium density that decreases with increasing distance between the layers.
