Friday Fun: Gross Out!

On hot days, your body keeps cool by cranking out a steady supply of clear, salty sweat. As the sweat evaporates, or turns into a gas and rises into the air, the heat on your skin goes along for the ride.

But a turkey vulture can’t make sweat. So it stays cool by peeing on its legs. As the urine evaporates, body heat escapes through the scales on the bird’s legs. What a great trick!
