Superfluidity is a remarkable property of quantum matter. Superfluids are quantum fluids which flow without viscosity, conduct heat in unusual ways, do not rotate like classical fluids, etc. I will show some of these properties with video sequences of liquid helium and present the main ideas which allow their understanding. Thanks to the recent discovery of superfluid gases, it is also possible now to see the link between superfluidity and Bose-Einstein condensation. As we shall see, the existence of this link has been a matter of controversy from 1938 until now.
