Clouds form when water vapor condenses into minute droplets or ice crystals, a process often hastened by tiny particles floating in the air known as aerosols, which give water molecules something to cling to. Yet when it comes to releasing that water, people are still in the dark as to why some clouds let loose a torrent while others don't shed a single drop. Ravilious examines the role microbes play in the murky inner lives of clouds.
