Kamri introduces a video on how submarines work, featuring marine biologist David Gruber. They discuss the structure of submarines, which have two hulls and ballast tanks that control buoyancy. By filling these tanks with water or air, submarines can dive or rise. David explains that submarines use SONAR, a system of sound waves, to navigate underwater. The video concludes with a recap of the submarine's functions and an invitation to watch more episodes.
