How things work: Submarines 🌊⚓🫧

Author: Sleep Tight Media | Bedtime Science Podcast For Kids & Starglow Media November 5, 2025 Duration: 29:06
In this episode we explore how submarines dive, hover, and rise through the ocean. We'll discover the special ballast tanks that can fill with water or air to make the submarine heavier or lighter, learn about Archimedes' principle—the rule that explains why things float or sink—and find out how dive planes steer the boat up and down while the pressure hull keeps everyone safe from crushing water pressure.Grown-ups: we value your feedback.
