Why Does Vinegar Erase Stains? | Acids, Bases & Kitchen Chemistry
How do animals survive freezing solid in winter? Discover natural antifreeze chemistry in this educational STEM science podcast for homeschool kids.
Deep beneath the frozen forest leaves, a tiny wood frog turns as hard as a popsicle. Its heartbeat completely stops, its breathing pauses, and ice forms through its tissues—yet when spring warms the forest, it thaws from the inside out and hops away! Meet nature's ice chemists, remarkable creatures that brew their own sugary antifreeze to keep sharp ice crystals from tearing their cells apart.
