Jacques Piccard’s Deep Dive

from Let's Rewind! - Heroes Who Changed Everything - Little Thinkers!

Dive into an incredible true ocean adventure! Join Ben & Pia as we rewind to January 1960, when Jacques Piccard and Lieutenant Don Walsh climbed into the bathyscaphe Trieste and descended nearly seven miles to the Challenger Deep. This is a story of calm thinking, clever machines, and a tiny steel sphere facing the weight of the sea. Why this story is special: It shows real science in action, brave teamwork, and how small details saved a historic mission. Perfect for young explorers who love mystery, invention, and amazing discoveries! Historical Fun Fact: The bathyscaphe Trieste used gasoline for buoyancy and iron shot as ballast that could be released by magnets to make it rise again. Did you know? Could two people survive and return from nearly seven miles below the ocean surface inside a seven-foot steel sphere? Which story do you want to hear next? Tell Ben & Pia in the comments and we'll rewind together! #LetsRewind #JacquesPiccard #DonWalsh #Trieste #DeepSea #History #Exploration #STEM
