HTitle: "Why Don’t Penguins’ Feet Freeze?"Opening Line (Hook):"Have you ever wondered how penguins walk on ice without their feet freezing? Let’s solve this chilly mystery!"Main Script:"Penguins have a unique adaptation that keeps their feet from freezing. Their feet are specially designed with a complex network of blood vessels.This system, called countercurrent heat exchange, helps keep their feet at just the right temperature. Warm blood flowing from their bodies heats up the cold blood returning from their feet. This prevents heat loss and keeps their bodies warm while their feet stay cool enough not to freeze.Plus, penguins have thick skin and fat layers that help them survive in icy environments. They are truly nature’s masters of cold-weather survival!"Closing Line (Call-to-Action):"Isn’t that incredible?
