Blue World - Shark's "tonic Immobility" In The Bahamas + Diving

In a shark-filled adventure, Jonathan travels to the Bahamas to meet Neal Harvey, a world-renown shark handler who will attempt to teach Jonathan how to put Caribbean Reef sharks into a relaxed state known as tonic immobility! Then, Jonathan heads to NASA's Neutral Buoyancy Lab in Houston, Texas (USA), where astronauts train for space walking underwater, in a giant pool about half the size of a soccer field. Jonathan gets a rare and fascinating look into this high-tech diving as he ventures underwater with the astronauts.
