The video shows a person's hand holding a red balloon underwater. The balloon is then released and floats away, while a squid swims by. The squid is white and has a long body with a pointed head and a short tail. The water is dark and the lighting is dim, making it difficult to see the details of the squid and the balloon. The squid moves slowly and gracefully through the water, while the balloon drifts away from the person's hand.
