Black holes in higher dimensions present many properties not shared by their four-dimensional cousins. A very important one is the existence of instabilities. This talk is devoted to the Gregory-Laflamme instability, which has been known for almost 20 years, and for which so far there was only numerical understanding. I will explain how, very similarly to what happens in the AdS/Fluids correspondence, some Ricci-flat black holes in more than four dimensions are "holographically" described by fluid dynamics in lower dimensions. This description gives a very precise and simple analytical account of the Gregory-Laflamme instability.
