A video that caught my attention


Title of video: Is Santa real? (A Scientific Analysis)
This video is about a scientific analysis, whether or not santa claus is real.

From this video, I learnt that:
  • Reindeers and Caribou are the same species, and they shed their antlers during the winter.
  • A reindeer's coat contains 2 kinds of hair, a layer of short, dense hairs, covered with a layer of long, hollow hairs. These 2 kinds of hairs trap a layer of air in between, which insulates them from the cold.
  • Reindeers have 25% more blood vessels packed in their nasal cavities than we do.
