By comparing the procedure and result of the experiment of Gardon s board with the characteristics of chaotic motion, we find that the experiment of Gardon s board can be not only the model to illustrate that the particles follow definite statistical regularity in many particles random motions, but also a very good demonstration of the features of chaotic motion.
