  • The dome shape is so resilient that chicken eggs can endure up to 90 pounds of pressure.
  • Giraffes have high blood pressure (280/180) to pump blood to their brains and built-in compression stockings. The tight skin on their lower legs prevents blood from pooling.
  • Insects breathe without lungs! Tracheal tubes move oxygen into every cell in the body.
  • Velcro was inspired when a man struggled to pull plant burrs out of his dog’s fur.
