Understanding Blubber and Its Role in Keeping Warm

The video explores how animals in cold climates, like the Arctic and Antarctic, stay warm using blubber, a special fat layer. It explains how blubber acts as insulation, keeping body heat in and cold out. The video includes an experiment using shortening to simulate blubber, demonstrating its insulating properties. The experiment shows that a hand covered in shortening stays warmer in ice water compared to a bare hand. The video concludes with a call to explore more about animals in cold environments.
