Quantum-critic al strongly correlated systems feature universal collision-dominated colle ctive transport. Viscous electronics is an emerging field dealing with sys tems in which strongly interacting electrons flow like a fluid. We identif ied vorticity as a macroscopic signature of electron viscosity and linked it with a striking macroscopic DC transport behavior: viscous friction can drive electric current against an applied field\, resulting in a negative resistance\, recently measured experimentally in graphene. I shall also d escribe current vortices\, expulsion of electric field\, conductance excee ding the fundamental quantum-ballistic limit and other wonders of viscous electronics. Strongly interacting electron-hole plasma in high-mobility gr aphene affords a unique link between quantum-critical electron transport a nd the wealth of fluid mechanics phenomena.
