In the video, a person is seen holding a red ball above a fish tank. The fish tank is filled with water and there are several fish swimming inside. The person drops the ball into the water and the fish immediately swarm around it, trying to catch it. The ball is bright red and contrasts sharply with the blue and green colors of the fish and the water. The fish are of various sizes and shapes, but all seem to be attracted to the ball. The person's hand is visible as they hold the ball above the tank, but they do not enter the frame. The video is shot from above the tank, giving a clear view of the action.
