This is the U.S. Forest Service Rocky Mountain Research Station Fire Lab in Missoula, Montana. Here, researchers have spent 5 decades studying fire science — literally playing with it — to develop new models for predicting fire behavior, which helps them understand how to put out forest fires. Whether it’s wind speed, slope, air flow, or anything else that influences flames, scientists at this lab study fire in intimate detail. Our friends from Gizmodo joined us to explore the lab and learn about philosophies like the Fire Paradox, partake in fire-based experiments, and walk through a fire wind tunnel.
