Please observe at the internal structure of this artwork which is vacuum and filled with atmospheric pressure. When the artist heated a glass tube that has a large atmospheric pressure difference between the inside and outside, it softened a glass making it bumpy. And when the internal structure is filled with neon gas, luminous discharge phenomenon occurs. Since the glass tube has narrow and wide areas, the discharge becomes unstable and the light fluctuates (Waves). Due to this phenomenon, the light visualizes the pressure of the atmosphere which cannot be directly perceived.
