What is the Mariana Trench?

Have you ever wondered how deep the ocean really goes? In 1960, two explorers named Jacques Piccard and Don Walsh decided to find out! They squeezed into a tiny, freezing cold steel ball attached to a giant underwater blimp called the Trieste. Together, they sank nearly 7 miles down to the deepest, darkest place on Earth: the Mariana Trench! It took almost five hours to slowly descend through pitch-black water. The crushing weight of the ocean was so heavy that a window suddenly cracked with a terrifying BANG! But they didn't give up! When they finally touched the ocean floor, they found something completely shocking: actual living sea creatures swimming where scientists thought absolutely nothing could survive! Their incredible discovery proved the deep ocean was full of amazing mysteries and completely stopped dangerous plans to dump toxic waste down there! Believe it or not, no human returned to this extreme depth for another 52 years! Join Mira and Finn as they eat chocolate bars and sink to the very bottom of the sea!
