The Big Adventure Series: The Big Submarine

In this educational video, children discover how these submersible ships work whilst onboard a Trident submarine. The video answers many kid questions, such as what to do if there's a leak, how long the crew can live underwater, and where they sleep. There's a brief history of the first submarine and footage of a research sub thousands of feet below the water. A great choice for children who are crazy about boats and "things that go."
