The Slow Mo Guys Gav and Dan show you just how dangerous water poured on an oil fire can be. Some water splashes the flaming oil around, and the water also evaporates into steam, which expands and pushes more flaming oil vapors everywhere.
The more the oil splashes, the more oil vapor is exposed and combusts, making the fire really big. This might be the most beautiful demonstration of explosive oil fire at 2500fps super slow motion plus water mixed together you have ever seen. But never put out an oil fire with water!
