The video shows a group of children standing in front of a glass aquarium tank. They are watching a whale swimming in the water. The whale is moving around the tank, and the children are watching it with interest. The tank is large and has a clear glass wall, allowing the children to see the whale up close. The whale is the only animal in the tank, and it appears to be healthy and active. The children are standing on the other side of the glass, and they seem to be enjoying the experience. The lighting in the room is bright, and the water in the tank is clear, allowing the children to see the whale clearly.
