Abstract A stable structure of tennis tower can be formed by stacking tennis balls to a certain structure. This paper will explore the structural stability of stacked tennis tower and the structural limit of the tennis tower and give the factors that limits the height growth of the tennis tower by experiments. It’s proved that the friction coefficient of tennis surface is not a constant but gradually decreases with the increase of the pressure applied. Based on this conclusion and experimental data, it is deduced that the practical stacking limit of tennis tower is about 11 layers.
