The video shows a fish tank with a clear glass top. The water inside the tank is green and murky, and there is a tube running through the tank. The tube has a yellow substance inside it, which is being pumped into the water. The substance is being released at a steady pace, and the water in the tank is slightly agitated due to the addition of the substance. The fish tank appears to be placed on a wooden surface, and there is a reflection of a person visible in the glass top of the tank.
