  Several general arguments indicate that the event horizon behaves as a
stretched membrane. We propose using this relation to understand gravity and
dynamics of black objects in higher dimensions. We provide evidence that (i)
the gravitational Gregory-Laflamme instability has a classical counterpart in
the Rayleigh-Plateau instability of fluids. Each known feature of the
gravitational instability can be accounted for in the fluid model. These
features include threshold mode, dispersion relation, time evolution and
critical dimension of certain phase transitions. Thus, we argue that black
strings break in much the same way as water from a faucet breaks up into small
droplets. (ii) General rotating black holes can also be understood with this
analogy. In particular, instability and bifurcation diagrams for black objects
can easily be inferred. This correspondence can and should be used as a guiding
tool to understand and explore physics of gravity in higher dimensions.
