There was a video of some people dumping cinnamon powder on someone in northern Europe as part of some tradition and the cloud spontaneously ignited.Īs an aside, those old cellulose ping pong balls could spontaneously combust if many of them rubbed against each other like perhaps in a box. This happens most commonly with grain, flour and sawdust, but any dry, organic powder could potentially burst into flame if you get the mix right. Because the dust is so dense, the heat from the specks bursting into flame sets fire to nearby specks and within seconds you have a mighty conflagration. When you have a large amount of small granules thrown into the air, they mix with the air and the friction from the grains rubbing together can trigger combustion.
