Classical gas of one-dimensional rigid spheres (1D Tonks gas) is one of the few examples of exactly solvable interacting many-body systems. The model is known for almost a century, but its properties are still extensively studied. Recently, the interest in the system was revived, because it constitutes the simplest non-trivial example of a model described within the Generalized Hydrodynamics (GHD) framework. The GHD theory describes large-scale behavior of generic classical and quantum integrable models in one dimension. I will review the most important static and dynamic features of the system and give a sketch of present research directions.
