Porous stone has the property of housing many microorganisms and purifying water, but because of its many cavities, it is lightweight and moves even with weak water flow. In this work, the sound was collected with a microphone, and the theme of the water being crushed into sand and the rocks being transformed by the crushing was used to create the work. The collected sound is played through a speaker, and since there is a stone above the speaker, the stone is crushed by the sound vibration. The sound of the rocks being crushed is also collected by a microphone, and the ripples are created by the sand in the jar. The change in the thickness of that sand changes the amount of bubbles in the tank, and all of this is a mechanism for circulation.
