Abstract: Recent advances in materials science have made it possible to achieve conditions under which electrons in metals start behaving as highly viscous fluids, "thicker than honey", and exhibit fascinating hydrodynamic effects. In this short review we provide a popular introduction to the emerging field of electron hydrodynamics.<br />Comment: 13 pages, 5 figures, submitted to Physics Today on July 28, 2019
