Abstract: We will present a model of pinned balls with gravity. A finite number of balls are arranged along a vertical line. The balls have pseudo-velocities and pseudo-collisions. We address the questions of neighborhood irreducibility and the existence of stationary probability for the process representing the balls. The proofs involve boundedness in probability on average and the weak  Feller property.
