  Using holographic duality, we present results for both head-on and off-center
collisions of Gaussian shock waves in strongly coupled $\mathcal N = 4$
supersymmetric Yang-Mills theory. The shock waves superficially resemble
Lorentz contracted colliding protons. The collisions results in the formation
of a plasma whose evolution is well described by viscous hydrodynamics. The
size of the produced droplet is $R \sim 1/T_{\rm eff}$ where $T_{\rm eff}$ is
the effective temperature, which is the characteristic microscopic scale in
strongly coupled plasma. These results demonstrate the applicability of
hydrodynamics to microscopically small systems and bolster the notion that
hydrodynamics can be applied to heavy-light ion collisions as well as some
proton-proton collisions.
