Are you aware that a single droplet of water can cause sun rays focus enough to start a fire? Imagine playing around with magnifying glass. It ain't guaranteed

Are you aware that a single droplet of water can cause sun rays focus enough to start a fire? Imagine playing around with magnifying glass. It ain't guaranteed, but take 1 billion of those drops, a mix of good conditions (no rain, just droplets from morning dew in otherwise dry place) and things will eventually happen naturally. I've seen it caught on camera by BBC team in some african documentary, a single droplet around bird's nest causing significant fire.
