      [Don’t try it at home!]

      Take a can of coffee, flour and some flame. Blow the flour into the flame and you create a mini fireball.

      Flour made from the sugar-family, and they burn easily (If you have ever set fire to a marshmallow?) Flour grains are so tiny that they burn instantly. When one grain burns, it lights other grains near it, and the flame front can flash through a dust cloud with explosive force.
