This is an installation that moves house dust with static electricity. We define house dust as an artificial life on two sides of the same coin with human activity. Fear of invisible substances such as radioactivity and the new coronavirus is only increasing. There is also violence in chemistry, such as when over-sterilizing kills the indigenous bacteria needed for our skin, making the skin rough. We also know that 45% of human genetic information is a virus or something like a virus. An invisible substance may be said to be a substance that is not trying to see its substance due to lack of knowledge or prejudice. We focused on a substance called dust, which is always generated in the environment where people are present but tends to be avoided.
