In the video, a person is holding a small, white, rectangular object with a black design on it. The person is moving the object in front of a fish tank, which has a green gravel bottom and is filled with water. The fish tank has a variety of fish swimming around, including a large orange fish and a smaller blue fish. The person continues to move the object around, and the fish swim around the tank, occasionally coming up to the glass. The lighting in the room is bright, and the background is blurred, but it appears to be a room with a window.
