Abstract: Relativistic hydrodynamics describes the expansion of the quark-gluon plasma formed in ultrarelativistic heavy-ion collisions. I discuss what experimental observables tell us about the quark-gluon plasma. At LHC energies, the mean transverse momentum of outgoing hadrons is proportional to its temperature. This provides an experimental measure of the equation of state, which is in agreement with lattice QCD calculations. The viscous damping of elliptic and triangular flows is determined by effective viscosities, which I define in terms of the temperature-dependent shear and bulk viscosities. I then briefly review some of the successes of the hydrodynamic picture in describing event-by-event fluctuations, in particular for proton-nucleus collisions. I conclude by listing some open problems.
