Once upon a time, a bare soot particle - spat out from a combustion engine in Paris - decided to travel to the high-alpine site Jungfraujoch. While trying to be mixed up to the free troposphere, it got exposed to solar radiation making it sweat. Desperate tries to cool down by forming a cloud droplet failed at first, quite the contrary, adsorbing condensable vapours made it sweat even more. Eventually, the acquired coating showed compassion and absorbed plenty of water in the updraft along the mountain slopes. Passing by the Jungfraujoch as a fully grown cloud droplet, allowed it to annoy the tourists and excite the aerosol-cloud interaction scientists. We don't know whether it even formed an ice crystal, however, it certainly lived happily ever after ... unless it got washed out.
