The video shows a person's hand holding a tube and placing it into a fish tank. The tube is then connected to a machine that starts to pump air into the tank. The fish tank is filled with water and has various types of fish swimming around. The person adjusts the tube and the machine to ensure that the air is being pumped evenly throughout the tank. The fish seem to be enjoying the air bubbles and are swimming around the tank. The video is shot in a well-lit room and the fish tank is placed on a table.
