How fire scientists see through flames

Researchers have figured out how to see through flames: it just takes blue LED theater lights, a camera filter, and a research facility where you can light test buildings on fire.The scientists tasked with understanding how fire destroys structures and devours our possessions need to watch these things burn — in the laboratory, that is. This research is key for keeping people safe, but it’s not easy: there’s soot, there’s smoke, and there are the flames to contend with.
