The video shows a group of people walking through a tunnel that is underwater. The tunnel is made of glass and has a blue carpet on the floor. The people are dressed in casual clothing and seem to be enjoying the experience. The water outside the tunnel is clear and blue, and you can see fish swimming around. The tunnel is surrounded by a wooden deck, and there are tables and chairs set up for people to sit and enjoy the view. The video gives a sense of adventure and exploration as the people move through the tunnel and observe the marine life around them.
