Hidden in the Desert, This Clever Shrub Has Built-in Air Conditioning!

Deep in Death Valley, one of the hottest places on Earth, an amazing little plant called the Arizona honeysweet stays cool by sweating water from its leaves! This clever trick is called evaporative cooling (using evaporating water droplets to drop the temperature), and it keeps the shrub a whopping 13 degrees Celsius cooler than the baking desert air. Isn't it incredible that a plant figured out how to make its own personal air conditioner?
