It is a well-known fact that a little fine dust in a glass tube containing a vibrating column of air disposes itself in recurring patterns. These striped dust patterns are called as “Kundt's Dust Figures” in honor of his discovery. The purpose of the present study is to apply the Kundt's method to solid-liquid mixtures for making concentrated solid clusters in a tube. Ultrasonic wave was used as a source of vibration. Two types of polystyrene particles and fine titanium oxide particles (powder) were used for the experiments.<BR>As the results of the experiments, the neutraly buoyant polystyrene particles formed regular stripes of concentrated clusters in salt water. With increasing the particle concentration, the stripes of the clusters disappeared and a massive cluster was gradually formed at the upper part of the tube. The particles slightly heavier than liquid also made a massive cluster in the middle of the tube. The fine titanium oxide particles did not show clear cluster patterns, however, after draining the mixture, the particles remaining on the inside wall of the tube indicated the formation of weak stripes.
